PRODUCT DESCRIPTION
Dymax Multi-Cure® 6-621-GEL adhesive cures upon exposure to light and is designed for rapid assembling of parts made of metal, glass, ceramic, phenolic, filled polyamide, and other materials. Dymax 6-621-GEL adhesive is specially formulated to cure with heat in applications where shadow areas exist. Dymax Multi- Cure materials contain no nonreactive solvents. Their ability to cure in seconds enables faster processing, greater output, and lower processing costs. When cured with Dymax light-curing spot lamps, focused-beam lamps, or flood lamps, they deliver optimum speed and performance for industrial product assembly. Dymax lamps offer the ideal balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with RoHS directives 2015/863/EU.
