Phenolic & Filled Plastics, Glass, and Metal Adhesive with Secondary Heat Cure

Multi-Cure® 6-621-VT adhesive quickly bonds parts made of metal, ceramic, glass, phenolic plastics, polyamide (filled/unfilled), and other substrate materials. 6-621-T cures with UV/Visible light, heat, or pre-applied activator. The product features secondary heat cure for applications where shadow areas on components exists. Industrial applications include coil winding, metal-to-glass bonding, as well as potting.

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. Multi-Cure® 6-621-VT is in full compliance with RoHS2 Directives 2015/863/EC.
