Ultra Light-Weld 3099 Adhesive for Bonding Acrylic

Product code: Dymax 3099

Manufacturer: Dymax

Package size: 1L

Shelf Life: 18 months

Dymax Ultra Light-Weld 3099 is designed for rapid bonding of PMMA, polycacsbonate, glass and other plastic substrate. The product is formulated with a UV/Visible light and secondary ambient moisture-cure system for curing in shadow areas and fluoresces blue for in-line inspection under low-intensity “black light” (365 nm). Dymax Ultra Light-Weld materials contain no nonreactive solvents and cure upon exposure to light. 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, supplemented by secondary moisture cure, they deliver optimum speed and performance for plastic bonding, sealing, and encapsulation. 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.
