MAKING MANUFACTURERS MORE EFFICIENT Realizing the tremendous opportunity for cost savings, expanded design capabilities, and environmentally “friendly” bonding and sealing solutions, Dymax introduced UV lightcurable adhesives and coatings to manufacturers in the early 1980’s. Since that time the company has specialized in lightcuring assembly solutions and now offers the broadest range of light-curable materials available and a complete line of lightcuring equipment. Our materials and curing equipment are used in a wide range of medical, electronic, industrial, aerospace, optical, auto-motive, packaging, and appliance applications. Visit the Dymax Web site at www.dymax.com to learn more about our light-curing systems and compatible adhesives. 2 Overview of Light-Curing Systems SPOT-LAMP SYSTEMS Dymax spot-lamp systems provide high intensity (up to 17,000 mW/cm2 (320-395 nm)) curing over a small area (typically <½", 5 mm diameter). These intensities usually result in a 0.5-5 second cure time. Available in both UV, visible, and LED light-curing models, Dymax spot-curing systems utilize an integral timed/manual shutter and typically require little external shielding. An intensity adjustment feature aids users in both validating and controlling a light-curing process. Spot-lamp systems are ideal for curing small areas quickly and can be easily integrated into an automated assembly process or used as a turnkey bench-top systems. Learn more about Dymax spot-curing lamps on pages 7-10. BlueWave® 200 Spot-Curing System with Intensity Adjustment SPOT/FLOOD-LAMP SYSTEMS Dymax offers flexible LED light-curing systems which can be easily configured as a spot lamp or a flood lamp. These units provides all the benefits of Dymax’s advanced LED light-curing technology in a flexible system design that can adapt to meet changing business and application needs. Learn more about Dymax spot/flood curing systems on pages 11-12. BlueWave® LED DX-1000 Spot/Flood Lamp System LIGHT-CURING FLOOD-LAMP SYSTEMS Dymax light-curing flood-lamp systems offer moderate to high intensity (75-225 mW/cm2) over a larger area (typically 5" x 5" or 8" x 8" (127 mm x 127 mm or 203 mm x 203 mm)). UV, visible, and LED light-curing models are available. These lamps are ideal for curing areas larger than ½" (12.7 mm) in diameter or curing many small parts simultaneously. Dymax light-curing flood-lamp systems can be incorporated into conveyors, automated assembly systems, or used as turnkey bench-top units. Learn more about Dymax light-curing flood-lamp systems on pages 15-17 of this guide. 3 ECE 2000 Flood Lamp with Light Shield and Shutter Overview of Light-Curing Systems CONVEYORS Dymax conveyors incorporate either flood or focused-beam curing systems. The benefits of light-curing conveyors include consistent cure times and the ability to cure larger parts. Conveyors also completely shield operators from UV light. Dymax conveyors have 12" wide belts, and can be configured for 6" and 12" width curing with UV flood lamps or 5" and 10" with LED flood arrays. Conveyor speed is tightly controlled and typically ranges from 1-32 feet per minute. Dymax light-curing conveyors can be outfitted with different types of lamps and up to four lamps on a single conveyor. Learn more about Dymax light-curing conveyors on pages 20-24. RADIOMETERS A radiometer is a device that measures the intensity and/or dose associated with light of specified wavelengths. UV light is, by definition, not visible and so a radiometer is required to determine UV intensity. Dymax’s ACCU-CAL™ radiometers are ideal for measuring the intensity of spot lamps, flood lamps, and conveyors. These radiometers measures intensity and dose in the UVA (320-395 nm) range. The ability to measure light intensity is useful for three reasons: maintaining a controlled light-curing process, providing a “worker friendly” light-curing process, and measuring light-transmission rates through substrates. Learn more about Dymax radiometers on pages 25-26 of this guide. UVCS 12" Wide UV Light-Curing Conveyor with Two Dymax 5000-EC Flood Lamps ADDITIONAL CUSTOM EQUIPMENT This guide contains the most popular Dymax light-curing systems and radiometers. Additional turnkey equipment and accessories are available including additional conveyors (wider, shorter, faster, or higher clearance), dispensing systems (time/pressure syringe dispensers, and valve/ pressure pot systems), dispensing needles, and more. In some cases, Dymax will custom design a light-curing system to fit your specific needs. Contact Dymax directly for more information regarding custom equipment or additional equipment not contained in this guide. ACCU-CAL™ 50 Radiometer 30" Wide UV Light-Curing Conveyor 4 Fundamentals of Light Curing Developing a successful light-curing process requires knowledge of the following key concepts. Higher Intensity = Faster Cures – Intensity is the light energy reaching a surface per time and it is often measured in mW/cm2. Higher intensity light (of the proper wavelengths) will generally provide faster cure. Shortwave and Longwave Bulbs – Dymax UV light-curing systems can be outfitted with either shortwave bulbs (emphasizing UVB and UVC) or longwave bulbs (emphasizing UVA and visible light). Longwave bulbs are recommended for curing most Dymax (and similar) light-curing materials due to their superior depth of cure and substantial visible-light intensity. The chart at the bottom of this page describes the portion of the electromagnetic spectrum emitted by standard Dymax longwave bulbs. Distance and Substrates Affect Intensity – Distance from a light-curing lamp always affects intensity. Intensity decreases with increasing distance from both spot lamps and floodcuring systems, especially spot lamps. Intensity decreases with increasing distance from the focal point for focused-beam systems. Intensity is also reduced when curing through substrates that transmit less than 100% of the light used for curing. Advances in light-curable adhesive technology now allow curing through most translucent substrates, even those that block UV completely. that curing is complete when further light exposure no longer improves product properties. Quantitative testing of cured specimens can be used to determine the minimum exposure time and/or minimum intensity required for complete cure. The graph on page 28 shows how this method could be used in a bonding application. Shadows – Light-curable materials will not cure unless exposed to light of appropriate wavelength, intensity, and duration. For applications where shadowed areas may be an issue, Dymax offers a line of light-curable materials that are formulated to also cure over time with heat or moisture. Oxygen Inhibition – In some cases, light-curable adhesive surfaces exposed to oxygen during curing may remain tacky after cure. This is caused by oxygen inhibition. Oxygen in the air actually slows the cure at the top-most layer of an airexposed coating surface. This tackiness does not necessarily indicate incomplete cure and can be observed with some materials, even after complete cure. In general, there are four ways to minimize or eliminate the tackiness associated with oxygen inhibition: ■ Longer and/or Higher Intensity Cure – In many cases, curing longer or with higher intensity will minimize or eliminate a tacky surface. ■ Use of “Shortwave” Bulb – Use of a UVB (shortwave) bulb instead of a UVA (longwave) bulb may also help to eliminate surface tack. A UVB bulb may, however, result in a limited depth of cure. Limited Depth of Cure – Since light-curable materials themselves absorb light, each has a maximum depth of cure. For most Dymax products, this depth is between ¼" (6.35 mm) and ½" (12.7 mm). ■ Choose an Alternate Dymax Material – An alternate formulation may cure “tack free” more readily. ■ Blanket with Inert Gas – Blanketing exposed resin surfaces with inert gas (like nitrogen or argon) during cure can often eliminate the problem of oxygen inhibition completely. Determining Complete Cure – Changing from a liquid to a solid is a simple definition of cure. A more complete definition is 5 Designing a Light-Curing Process There are several factors to consider when designing a lightcuring process. beneath three separate lamps. Brief interruptions during cure are acceptable. Intensity – A well-designed light-curing process incorporates a curing system with excess intensity. Excess intensity provides both a safety margin and long bulb life. See page 28 “Setting Up and Monitoring a Light-Curing Process” for specific intensity and safety margin guidelines. Safety – Proper equipment set-up and operator training are the keys to developing a safe light-curing process. Always follow the operation manual to ensure safe installation. Proper shielding, protective equipment, and eye protection are required to ensure a safe light-curing process. Spectral Output – It is important to match the spectral output of the lamp to the material and application. Dymax supplies both shortwave bulbs (also called Mercury or “H”) and longwave bulbs (also called Metal Halide or “D” bulbs). In general, longwave bulbs emit primarily UVA providing superior depth of cure, while shortwave bulbs emit primarily UVB/UVC providing superior surface cure for coatings and inks. Longwave bulbs are recommended for most applications involving Dymax materials. Controls – Unless exposed to light of sufficient wavelength, intensity, and duration, most light-curing materials will remain uncured. To insure a consistent exposure time, timed shutters are standard on spot lamps and available for most flood and focused-beam systems. A digital speed controller on Dymax conveyors insures consistent exposure times. Curing Area – The size of the area to be cured may dictate which type of lamp is appropriate. Spot lamps are typically used to cure areas less than ½" (12 mm) in diameter. Flood or focused-beam lamps are used when curing large areas (up to 8" x 8" (203 mm x 203 mm)). Multiple flood lamps or conveyors can be used to cure even larger areas. Avoid Creating a “Bottleneck” – Ideally, the light-curing process is designed to be faster than the limiting or “bottleneck” step in the overall manufacturing process. Dispensing, assembling, testing, or packaging parts while other parts are curing will maximize efficiency. Lamp intensity should be regularly monitored with a radiometer. Bulb replacement and/or appropriate lamp maintenance should be conducted when intensity dips below a pre-determined minimum value. Bulb Life – The cost of replacement parts can be an important consideration when selecting a light-curing system. Generally, low bulb-replacement costs are achieved by selecting a lamp with intensity to spare, thereby extending allowable bulb life. Price Per Bulb x Frequency = Bulb Replacement Cost Curing Multiple Parts Simultaneously – In some cases, it is more efficient to cure many small parts simultaneously using a flood or conveyor than to cure each part individually. For example, a spot lamp may cure one small part every three seconds (or 20 parts-per-minute) whereas a flood lamp may cure 20 small parts every 15 seconds (or 80 parts-per-minute). Multiple Cure Stations – On an automated production line where the required cure time exceeds the index/cycle time, multiple cure stations can be used. For example, if a part requires nine seconds to cure and the index/cycle time is only three seconds, each part can be cured for three seconds Dymax Light-Curing Spot Lamps are Ideal for Automation! 6 Light-Curing Spot-Lamp Systems BLUEWAVE® 75 WITH INTENSITY ADJUSTMENT The BlueWave® 75 UV light-curing spot lamp is simple to operate and is designed for use with light-curable adhesives, coatings, and encapsulants.

There are several factors to consider when choosing a lightguide. Length – Lightguides are commonly one meter long although other lengths are available. Curing Area/Intensity vs. Distance – The UV and visible light emitted from a lightguide diverges. As a result, intensity decreases and curing area increases with distance from the end of the light guide. The chart below describes this relationship clearly for the 5-mm liquid lightguide. Diameter – Single-pole lightguides are available with 3-mm, 5-mm, or 8-mm inside diameters. Although the 5-mm lightguide will register a higher intensity, the 8-mm lightguide provides more curing power (intensity x area) because a larger lightguide opening captures more of the light emitted from the bulb. Each pole of a multi-pole lightguide has an inside diameter of 3 mm. Multiple Poles – Light emitting from a spot lamp can be channeled through a single lightguide (single pole) or split between multiple lightguides (multiple poles). Each pole of a multi-pole lightguide emits equal intensity (typically 10% for liquid-filled lightguides) and all share a common shutter. Both liquid-filled and quartz-fiber multi-pole lightguides are available from Dymax. Connection – There are basically two types of connectors used in the spot lamp industry, “Wolf” and “D” connectors. Dymax provides lightguides with both connector types, although “D” connectors are an industry standard and compatible with current Dymax lamp designs (older Dymax designs utilized “Wolf” connectors).

LEDs offer many advantages over conventional bulbs including constant intensity, no required warm-up time, and a life span of over 20,000 hours. The relatively narrow frequency band produced by LEDs also generates cooler curing temperatures making this unit ideal for use with thermally sensitive substrates. 17 BlueWave® LED Flood Lamp System Shown with VisiCure™ Array and Standard Mounting Stand When compared to other LED units, the BlueWave® LED Flood provides much higher intensity and more overall uniformity across the active area. These benefits allow shorter cure times, and in turn, faster manufacturing throughput. The following graph illustrates the Dymax BlueWave® LED Flood’s high uniformity when multiple arrays are positioned next to each other. This is especially important in conveyor applications to ensure a consistent cure across the entire substrate. BlueWave® LED Flood with Two VisiCure™ Arrays (Mounted Face-to-Face) Accessories for Flood Lamp Systems Dymax light-curing flood lamps can be outfitted with the shutters and shielding shown below. Additional shutters, enclosures, and accessories may be available. SHUTTERS MOUNTING STANDS Standard Mounting Stand Kit – A simple and cost effective mounting stand with adjustable height. For use with the BlueWave® LED Flood. PN 41268 Turning a bulb off and on between cycles is not practical since each off/on cycle shortens bulb life and requires a 5-minute warm-up period. A shutter, however, can be used to shield a flood system between cycles. Shutters control exposure time, reduce heat on the work surface, and shield operators from exposure to UV light. There are two types of shutters pictured below. Both ZIP™ and manual shutters are compatible with Dymax flood lamps. ZIP™ Shutter – Timed and manual modes. Foot pedal or PLC controlled.

These are typical output intensities measured with the ACCU-CAL™ 50-LED Radiometer. 2 Intensity 24 Radiometers for Light-Curing Systems A radiometer is a device that measures the intensity and/or energy associated with light of specified wavelengths. UV light is, by definition, not visible and so a radiometer is required to determine UV intensity. Dymax offers the ACCU-CAL™ 50 for spots, floods, and conveyors. The ability to measure light intensity is useful for three reasons: 1. 2. 3. Maintaining a light-curing process – A radiometer can measure whether a light-curing system is providing intensity above the “bulb change” intensity. A radiometer is to a light-curing process what a thermometer is to a heat-curing process. Providing a worker-friendly light-curing process – A radiometer is required to determine if any UV light is reaching operators or bystanders. Measuring transmission rates through substrates – A radiometer can be used to measure the transmission rates of various wavelengths through substrates that absorb UV and/or visible light. To assure an effective curing process it is critical to measure the light intensity reaching the light-curable material below the intervening substrate. ACCU-CAL™ 50 RADIOMETER Dymax’s ACCU-CAL 50 is capable of measuring both the UV intensity (mW/cm2) and dose (J/cm2) emitted from spot lamps*, flood lamps, and conveyors. This easy-to-use radiometer is compatible with 3-mm, 5-mm and 8-mm lightguides and only requires re-calibration once per year. Please refer to Dymax literature #Lit159 for more information. ACCU-CAL™ 50 RADIOMETER Part Number Measures Intensity Resolution Battery Life 39561 – UVA; compatible with all lamps except spot lamps* ACCU-CAL™ 50 Radiometer ACCU-CAL™ 50-LED RADIOMETER Dymax’s ACCU-CAL 50-LED can measure energy levels emitted from 3-mm, 5-mm, and 8-mm lightguides and LED flood lamps. This radiometer has a spectral sensitivity range of 350-450 nm and an intensity measurement from 1 W/cm2 to 40 W/cm2, making it ideal for measuring LED curing-source energy levels. A specially designed photo-sensor assembly provides repeatable measurements and protection from high temperatures associated with some LED systems on the market.

ACCU-CAL™ 50-LED Radiometer 25 Radiometers for Light-Curing Systems ACCU-CAL™ 50-V RADIOMETER ACCU-CAL™ 150 RADIOMETER The ACCU-CAL 50V radiometer is simple to operate and offers repeatable measurement of visible light. The ACCU-CAL 50V can measure visible light energy emitted from lightguides (3 mm, 5 mm, and 8 mm), flood systems, and conveyors. With a spectral sensitivity from 395 to 465 nm (blue portion of the visible spectrum), the ACCU-CAL 50V measures intensities from 1 mW/cm2 to 40 W/cm2. A specially designed photo sensor assembly protects the photo sensor from the high temperatures sometimes associated with today’s highintensity spot lamps. Please refer to Dymax literature #Lit236 for more information. Dymax’s ACCU-CAL 150 can measure UV light up to 10 W/cm2 emitted from stationary light-curing flood lamps or lamps used in conveyorized processes. This radiometer can be used to determine intensity (mW/cm2) or total energy as derived from intensity and exposure time (mJ/cm2). Calibration is recommended every six months to ensure proper operation of the radiometer. Please refer to Dymax literature #Lit290 for more information.

The fast cure, one-component nature of our UV light-curing technology has made it the process of choice for many manufacturers requiring a “Cure on Demand” assembly process. There are three common questions/concerns related to UV light-curing systems: UV exposure, ozone, and bright visible light. SHIELDING THE SOURCE OF UV Any substrate that blocks UV light can be used as a shield to protect workers from stray UV light. The following materials can be used to create simple shielding structures or blind corners: ■ Sheet Metal – Aluminum, steel, stainless steel, etc. Sheet metal should be coated black or black anodized to minimize reflection of UV and visible light. ■ Rigid Plastic Film – Transparent, UV-blocking plastics (typically polycarbonate or acrylic) are commonly used to create shielding where transparency is also desired. These rigid plastic films are available either water-clear or tinted, (to reduce visible light glare). ■ Flexible Film – UV-blocking, flexible urethane films can be used to quickly create workstation shielding. This UVblocking, flexible urethane film is available from Dymax. UV EXPOSURE Standard Dymax UV light-curing systems and bulbs have been designed to primarily emit UVA light1. UVA light is generally considered the safest of the three UV ranges: UVA, UVB, and UVC. Although OSHA does not currently regulate ultraviolet light exposure in the workplace, the American Conference of Governmental Industrial Hygienists (ACGIH) does recommend Threshold Limit Values (TLVs) for ultraviolet light. The strictest interpretation of the TLV (over the UVA range) for workers’ eyes and skin is 1 mW/cm2 (intensity), continuous exposure. Unless workers are placing bare hands into the curing area, it is unusual to exceed these limits. To put 1 mW/cm2 limit into perspective, cloudless summer days in Connecticut regularly exceed 3 mW/cm2 of UVA light and also include the more dangerous UVB light (primarily responsible for sun burns) as well. The human eye cannot detect “pure” UV light, only visible light. A radiometer should be used to measure stray UV light to confirm the safety of a UV light-curing process. A workstation that exposes an operator to more than 1 mW/cm2 of UVA continuously should be redesigned. UV adhesive light curing can be a regulatory-compliant, “worker-friendly” manufacturing process when the proper safety equipment and operator training is utilized. There are two ways to protect operators from UV exposure: Shield the operator and/or shield the source. SHIELDING THE OPERATOR ■ UV-Blocking Eye Protection – UV-blocking eye protection is recommended when operating UV light-curing systems. Both clear and tinted UV-blocking eye protection is available from Dymax. ■ UV-Blocking Skin Protection – Where the potential exists for UV exposure upon skin, opaque, UV-blocking clothing, gloves, and full face shields are recommended. 27 OZONE Standard Dymax bulbs (UVA type) generate an insignificant amount of UVC and therefore essentially no ozone1. Some UV light-curing systems, like those used to cure UV inks, emit primarily “shortwave” (UVB and UVC) energy. Upon exposure to UVC light (specifically <240 nm), oxygen molecules (O 2) split into oxygen atoms (O) and recombine with O2 to create Ozone (O3). The current, long-term ozone concentration limit recommended by ACGIH, NIOSH, and OSHA is 0.1 ppm (0.2mg/m3). BRIGHT, VISIBLE LIGHT The bright, visible light emitted by some UV light-curing systems may be objectionable to some workers and may cause eyestrain. Tinted eye protection and/or opaque/tinted shielding can be utilized to address this concern. SUMMARY UV light sources can be more “worker friendly” than many commonly accepted industrial processes, provided the potential concerns are addressed. Contact your Dymax representative for information regarding the proper use of Dymax UV light-curing systems. 1Dymax also provides special order “shortwave” bulbs that emit primarily UVB and UVC light. Contact Dymax directly for information regarding the use of “shortwave” bulbs. Setting Up & Monitoring a Light-Curing Process There are two parameters that must be considered to ensure a successful light-curing process, 1) intensity at the curing location and 2) cure time. Dymax recommends setting up and monitoring a UV light-curing process as follows: 1. Choose a Light-Curing Material (LCM) – Select an LCM that satisfies the performance requirements of the application. 2. Determine available light-cure time – Determine the cure time available so that the UV curing process is not a “bottleneck” in the manufacturing process. For example, if dispensing and assembly requires 12 seconds per part in a one piece flow process, the maximum available cure time is 12 seconds. For a light-curing conveyor, determine the minimum line speed required. 3. Choose a light-curing system – Choose the appropriate light-curing system that will fully cure the LCM within the cure time available. Dymax Applications Engineering can help you identify the best light-curing system for a specific application. 4. Determine the lowest acceptable intensity – The lowest acceptable intensity is that which fully cures the LCM in the available cure time (determined above). The lowest acceptable intensity can be determined through quantitative testing of parts cured at various intensities as shown in the diagram to the right. In the case of a focused-beam lamp on a conveyor, determine the lowest acceptable dose‡, not intensity. 5. Monitor and maintain intensity – Using a radiometer, monitor the UV light intensity at the bond line. If the intensity reaches the “bulb change” intensity, install a new bulb or conduct appropriate maintenance (see page 29 “Maximizing Lamp Performance”). In the case of a conveyor, dose (not intensity) should be monitored. If the resulting cure process is causing heat damage, a cooling fan or shorter cure time is recommended. If the resulting bulb life is too short, a longer cure time or higher intensity lamp is recommended. ‡Both residence time and intensity varies with lamp height on conveyors with focused-beam lamps. For this reason, it is better to monitor dose (J/cm2) on these systems rather than intensity. The most practical way to artificially lower the dose on these systems is to adjust the line speed. The following techniques may be used to artificially modify intensity to facilitate determining the lowest acceptable intensity. ■ Increase distance – Since light emitting from lightcuring lamps diverges, the intensity decreases as the distance from the lamp increases. This is especially useful for flood lamps. ■ Adjust Intensity – Some UV light-curing systems (like the BlueWave® 200 with intensity adjustment feature) allow users to adjust intensity. Note: As with any manufacturing process, it is advisable to operate with a safety factor. Dymax recommends a “bulb change” intensity that is 50-100% higher than the “lowest acceptable intensity”. 28 Maximizing Light-Curing Lamp Performance There are three ways to maximize lamp performance: 1. Proper Set-Up – The first key to maximizing lamp performance is proper set-up. Reference the operation manual provided with each Dymax lamp for instructions on proper set-up. After ignition, wait five (5) minutes before use to allow the lamp to reach full intensity. Then, use the following techniques to maximize intensity at the curing location. ■ Spot-Cure Systems – Maximize curing intensity by minimizing distance from the end of the lightguide to the light-curable material, while still covering the curing area. Positive airflow can prevent those vapors commonly emitted during cure from condensing on the end of a lightguide. Be aware that excessive bending, clamping, or set-screw tightening can damage lightguides. The minimum bend radii for standard lightguide diameters are as follows: ■ ■ ■ 2. 3-mm lightguides – 40-mm bend radius 5-mm lightguides – 60-mm bend radius 8-mm lightguides – 100-mm bend radius ■ Flood Lamps – Minimize distance from the bottom of the flood housing to the light-curable material. Note that distances 3" (76.2 mm) or more from the lamp housing provide the most uniform intensity across the curing area. ■ Focused-Beam Lamps – Place light-curable material at the focal point of the focused-beam lamp for maximum intensity. The focal distance for the Fusion® F300S is 2.1" (53.34 mm) below the lamp housing. Optimizing Bulb Life – The intensity of light being emitted from UV bulbs gradually decreases with usage (except in the Fusion F300S). This degradation cannot be avoided, but it can be minimized through proper operation. The longest bulb life is obtained by simply using the lamp continuously (not turning it off). The more often the lamp is cycled on and off, the more quickly the bulb degrades. The general rule of thumb is to leave the lamp on if it will be used again within an hour. 29 Once ignited, do not turn the lamp off for at least five minutes. Turning the lamp off before it has reached its operating temperature can damage the bulb. In addition, do not attempt to re-start a UV light-curing system until it has been allowed to cool for five (5) minutes. 3. Proper Maintenance – As with all production equipment, routine maintenance will optimize performance. In the case of a spot lamp, keep the end of the lightguide clean and replace it if it no longer transmits enough light (a lightguide simulator is available from Dymax to help determine lightguide transmission). See Lit#069 Lightguide Simulator for more information on lightguide and bulb maintenance. In the case of a flood lamp, the reflector and lamp base (sockets that the bulb fit into) should be cleaned and/or replaced as necessary. Please refer to the user guide for each light-curing system for further guidance on proper maintenance. 30 FREE DYMAX EQUIPMENT EVALUATION Contact your Dymax representative to initiate rental of Dymax UV light-curing equipment.
