Introduction
The entire Spectrum of Innovative Solutions
Ever since the commercialisation of ultraviolet light curing products
over three decades ago, Henkel has remained at the forefront of the
development of light curing adhesives, sealants and coatings for industrial
applications ranging from glass assemblies to plastic bonding and medical
device manufacturing. Adhesives that cure quickly on exposure to light
have swept across the industrial spectrum, gaining widespread acceptance
because of their compelling process cost reduction benefits and wide
range of properties.
Originally, light cure adhesives were formulated to be cured with ultraviolet (UV) light
sources, followed by UV/visible light curing systems. The latest generation of light
cure adhesives offered by Henkel relies solely upon the visible light spectrum to
deliver safe, efficient, immediate cure for a broad range of assembly applications.

Light Cure Technology – Your Benefits
Light cure technology offers a unique combination of performance,
design and processing benefits:
Cure on demand
• Material remains liquid until exposed to light
systems, then cures in seconds
• Allows time to align parts precisely prior to cure
• Choice of cure system determines cure time
Speed of cure
• Achieves high process speeds for maximum
throughput
• Fast cycling to subsequent process steps
Quality assurance
• Product presence monitoring by fluorescence
• Fast snap cure allows 100% in-line inspection
• Monitoring functions for cure parameters such as
intensity, exposure time, etc.
One part systems
• Automated accurate dispensing
• No need to measure or mix, no pot life concerns
• Solvent-free – 100% solid
Optical clarity
• Ideal for bonding clear and transparent
substrates with perfect aesthetic finish
• Greatly expand your design options

Loctite INDIGO™ Light Cure Adhesives
This revolutionary technology can rely solely on low energy light in the visible spectrum
to deliver all of the benefits of traditional light curing. It is ideal for a wide range of
applications and exceeds both industry and environmental sustainable standards –
ensuring a safer working environment, eliminating venting, reducing unnecessary energy
usage, and saving money through less replacement, maintenance, repair, and capital
investment costs. The products are designed for use on UV-blocking clear and selected
coloured substrates including translucent variations of blue, purple, grey, white and green.
®
Loctite Light Cure Adhesive Technologies
• Light curing acrylics, offering the most extensive variety of properties of all light cure
chemistries. A transparency equal to glass and clear plastics, as well as versatile
adhesion characteristics are their most notable properties
• Light curing silicones, which cure into soft, flexible thermoset elastomers and are
excellent for elastic bonding, sealing and leakproofing
• Light curing cyanoacrylates, offering outstanding plastic bonding capabilities
combined with rapid cure by low intensity light irradiation
• Light curing anaerobics with excellent metal bonding capabilities and outstanding
chemical resistance combined with shadow cure
®
Loctite Light Cure Solutions with Shadow Cure
Dual cure capability, effected by heat or activator, as moisture or anaerobic cure, can also
be provided to cure adhesives in shadowed areas. Dual cure expands the benefits of light
cure technology to non-transparent substrates, other adhesive technologies and application
areas.

Light cure adhesives offer clear advantages for glass applications and have been
the preferred option for many years.
• They achieve high transparency and show excellent stability even after long term ageing in hostile
environmental conditions including moisture, sunlight and dishwashers
• Their refractive index matches that of float glass, creating a virtually invisible bond line
• They create high strength bonds on all types of glass including float glass, crystal glass, fibre glass and
ceramic glass. They are particularly effective when bonding metal to glass
• The product range goes all the way from high strength grades for structural bonds to highly flexible types
for stress absorption within the bond line
• They greatly improve the ease of assembly and range of design options, eliminating the need for
drilling holes, or for mechanical fasteners to avoid stress peaks, and achieve a clean, modern design
with perfect cosmetic appearance

Plastic bonding adhesives can be cured
by UV and visible light and achieve low
stress, ultra clear bonds, making them
particularly suitable for bonding modern plastics.
• Transparency equal to the plastic substrate obtains invisible bond lines
• Temperature resistance and deformation behaviour match that of plastics, providing
for a high degree of long-term durability
• Capable of bonding transparent plastics, e.g. PC, acrylic, PBT, PVC and plasticised PVC,
most opaque plastics, e.g. PA, as well as most non-transparent or coloured plastics
• Various light cure technologies for adaptation to the wavelengths passing through clear
or UV-stabilised or translucent pigmented plastics
Applications
• Bonding and sealing of housing assemblies, lids, shells, windows into frames, sunglasses …
• Display cases and shelves, point of sale material …
• Medical device industry – needles, housings, adapters, connectors …

A large number of substrates are not transparent to light at all because
they are made of a material that does not allow light to transmit (e.g. metals,
ceramics, ferrites), or because they contain a non transparent additive
(e.g. black, colour additives).
The versatility of light curable adhesives for use in bonding and tacking, potting
and encapsulating, coating and sealing applications is further enhanced by products which
have a secondary cure mechanism to ensure residual or complete cure in shadowed areas not
reached by UV or visible light. For such joint configurations, light cure adhesives are available
with secondary cure capability. This secondary curing options include heat, moisture, activator or
as anaerobic cure.
Light cure adhesives offer benefits even when
non transparent substrates are involved:
•
•
•
•
10
Precise positional fixturing of parts to be bonded
Fast cure for high processing speeds and in-line quality control capability
Reliable cure of exposed excess adhesive fillets or squeeze-out
Cure in shadowed areas over time by secondary cure
Applications
Wherever fast cure of adhesive in fillets accessible by light offers a process benefit, e.g. for
• Fast fixturing of magnets, ferrites, ceramic parts …
• Fast positioning of parts in retaining joints …
• Fillet or surface cure, e.g. of post-applied product outside the bond area …

Equipment for Light Curing
Four major factors must be taken into consideration when designing a successful light cure application: emission spectrum
of the cure system, light intensity, transmission properties of substrate, and the required cure characteristics. As a
manufacturer of both the chemistry and the curing equipment, Henkel knows how to match light cure adhesives to the
correct dispensing and curing system.
