PRODUCT DESCRIPTION
Dymax Multi-Cure® 6-621-GEL-F Blue Fluorescing Adhesive for Metal, Glass and many Plastics is designed for rapid assembly of parts made of metal, glass, ceramic, or a variety of plastics. 6-621-GEL-F is a material specially formulated to cure primarily with UV/Visible light and include a secondary heat or activator curing function in applications where shadow areas exist. This product also fluoresces blue for in-line inspection under low-intensity “black” light (365 nm). 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 optimum balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with RoHS directives 2015/863/EU.
