Ultra Light-Weld® FIP/CIP Gasket Adhesive

Ultra Light-Weld® GA-120 form-in-place gasket resin cures in place with UV/Visible light for immediate parts processing and increased throughput. The product is ideal 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 as well as metal surfaces. Easily dispense this resin into intricate and complex component configurations. The added benefit of curing in-line allowing for increased production speed and greater output, as well as 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. Ultra Light-Weld® GA-120 is in full compliance with the RoHS2 Directives 2015/863/EU.


Durometer Hardness:  00-50

Compression Set % (85°C, 22 hr)* : 0.17

Substrates: Plastics; Metals

*Compression set is expressed as percentage of deflection per ASTM D395 Method B at 25% deflection. To determine percent recovery, subtract 1/4 of the value from 100%. For example, the recovery is 98.8% with a 5% compression set.
