Adhesive KTA SECTION* Installation instructions
Installation instructions ISERMATIC thanks you for choosing CRYSTAL: the frame and illuminated sign fabric tensioning system with many advantages. SIMPLICITY No make up No eyelets No ropes No welded edges CONTINUOUS TENSION No clamps No clips No screw system No strings AESTHETIC No joints No plates Adhesive KTA SECTION* for fixed frames glued to a rigid structure Product informati information & methods of o installation possible LIGHT No heavy rigid plates EASY TO INSTALL ing No need for heavy handling equipment. SAFETY /ml Tear proof up to 1360Kg/ml Can be bent manually in one axis to take on the shape pe of the support (under certain conditions, con nditions, please consult us) * Adhesive aluminium section e ection using a high performance adhesive hesive h i of the VHB™ type developed loped by 3M’s industrial gluess and adhesives department. 3M carried out various tearing and nd shearing tests at different stages of ageing as well as at different temperatures tures in order to validate the section’s adhesive dhesive strength. Facing strip The conta contact ct zone should alw always ways be on the ins inside ide of the frame Edging strip Directly D on th the ssupportt See details on the last page. Possibility of connection at rightangles SOLUTIONS POUR L'ENSEIGNE, LA COMMUNICATION, L'ARCHITECTURE The adhesive area should be in contact with the support for its whole width Installation of a adhesive KTA frame 1 These instructions give you details of how to assemble frames at right-angles directly by gluing to a surface that is rigid, flat and smooth such as natural or lacquered aluminium, lacquered Gel Coat, Alucobond, glass ... The adhesive section can of course be applied to other supports but we always recommend carrying out tests first. Under no circumstances can it be applied to the following surfaces: • Polyamide (PA), • Polyethylene (PE), • Polyacethal (POM), • Polypropylene (PP), • Polytetrafluorethylene (PTFE), • Silicones. For any special use, we invite you therefore, to contact our technical teams on: (+33) 4 74 86 69 90 PREPARING THE SURFACES When cleaning is possible, use ScotchBriteTM PURPLE to slightly abrade the support to give the best adhesion. - In all cases, clean the support using isopropyl alcohol. If cleaning is not possible, 3M recommends using wipes impregnated with an adhesive “primer”. This “delustres” the medium and gives the adhesive a better hold. Gluing surfaces must be clean, dry and free from dust. 2 INSTALLING THE SECTION - Heat the support using a heat gun. Heat enough but gently so as not to burn the support Remove the protective strip from the section and apply the adhesive KTA, exerting strong uniform pressure. Position the section correctly right from the start because gluing is instantaneous ! Pressure to be exerted is 2 kg/cm2. To accentuate and distribute pressure uniformly* during gluing, use manual pressure. * (use a piece of KTA, turning it over and applying it to the section to be fixed). To accentuate and distribute pressure uniformly during gluing, use strong manual pressure*. * Use the special tool to fit into the KTA profile distributing ideally the exerted pressure. - The profile has absolutely to be glued uniformly on all its back! It is important to check the gluing on all its length and to correct the eventual defects with a strong pressure using again the heat gun avoiding softening the glue. 3 VERY IMPORTANT: WAIT BEFORE INSTALLING THE FABRIC Minimal 36h In normal conditions, at ambient temperature (23°C), performance of the product’s adhesive reaches 90% after 24 hours. 72 hours are required to reach 100%. To reduce this time of 24 hours, the materials can be heated while maintaining uniform pressure. It is important to wait 36 hours at least before stretching the banner. The adhesive performance of this product is only guaranteed in the context of a minimum ambient temperature of 16°C during installation. 4 D ÉPOSE É VENTUELLE D UP RODUIT DÉPOSE ÉVENTUELLE DU PRODUIT Using a flat screw driver or scissors, raise one end of the section with a levering action. Repeat the same operation for the whole length to be lifted. To remove any marks left by the VHB adhesive, use a spatula or a sharp knife to peel off the residue. Installing and tensioning the fabric 1 • INSERTING THE FABRIC Installing and tensioning the fabric are central to the CRYSTAL system. It is for this reason that the method of assembly summarized below should be followed to the letter. It is also essential to use the tools recommended and chosen by ISERMATIC. *1 • FASTENERS The fasteners are pieces of facing about b 10 cm llong, cut with ih a bevel to avoid piercing the fabric during positioning. Your fabric must be larger than your frame by about 10 cm all round.. Install the positioning and pretensioning fasteners on the top part. Repeat the same operation on the bottom and sides, exerting moderate pressure on the fabric. Grip the fabric by engaging the outside facing to start with. C D C D B 3 • INSTALLING THE FACING *2 A *2 • PRINCIPLE OF INSTALLING THE FACING A 2 • INSERTING THE FASTENERS *1 Now fix and tension the fabric by installing the facing, following the same order as the fasteners were inserted. Remove the fasteners as you proceed (see video on the web site). B 4 • TENSIONING THE FABRIC Using the anti-rebound mallet, drive in the facing to create the tension until it finally clips. Thanks to the mechanical effect of the facing installation principle, the fabric stretches automatically for a perfect fit. 5 • TRIMMING THE FABRIC Once the fabric has been tightened correctly and the corner cuts made, excess fabric should be removed using a sharp knife, generally along the outside edge of the facing strip.
