Flexible See-Cure Adhesive for Bonding Multiple Plastics

Ultra Light-Weld® 3221-SC is designed for rapid bonding and laminating of PC, PVC, PMMA, PA, PU, and other plastic substrates. Dymax adhesives formulated with See-Cure color-change technology start out bright blue in their uncured state, making them very visible when dispensed onto substrates. The blue color of See-Cure products disappears when the adhesive is fully cured. Typical applications include plastics assembly, plastics lamination, metal-to-plastic bonding, and appliance assembly.

Dymax materials are solvent free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.
