Ultra Light-Weld® FIP/CIP Gasketing Resin

Dymax Ultra Light-Weld® GA-120 is a UV/Visible curable Form-In-Place/Cure-In-Place (FIP/CIP) Gasket formulated for speaker assembly, sound dampening, and automotive enclosure applications which require a soft, tacky, flexible gasket with good deflection and self-leveling viscosity. This gasketing material has good adhesion to plastic and metal surfaces. This resin can be dispensed into intricate and complex component configurations with the added benefit of curing in-line allowing for increased production speed, greater output, and reduced inventories.

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.
