PERMABOND® UV639 is a UV-curing adhesive developed for use on plastics. It has superb adhesion to acrylic, polycarbonate and PETG. This adhesive can also be used to bond glass, metals and other materials. UV639 cures to give a colourless bond so is ideal for applications where aesthetic appearance is vitally important Additional Information This product is not recommended for use in contact with strong oxidizing materials. Information regarding the safe handling of this material may be obtained from the Safety Data Sheet. Users are reminded that all materials, whether innocuous or not, should be handled in accordance with the principles of good industrial hygiene. Surface Preparation Surfaces should be clean, dry and grease-free before applying the adhesive. Particular care should be taken to remove silicone based cleaning agents which may have been used previously to clean glass. Some metals such as aluminium, copper and its alloys, will benefit from light abrasion with emery cloth (or similar) to remove the oxide layer. Isopropanol can be used to degrease most surfaces. Where thermoplastic surfaces are involved we recommend tests are done to ensure compatibility, mold release agents may affect bond strength. Directions for Use 1) Adhesive can either be applied directly from the bottle or dispensed via automated dispensing equipment for more accurate dosing. Minimise exposure of product to ambient light. 2) It is important to try to prevent air entrapment within the joint as this could be detrimental to the finished appearance of the adhesive.
