Flexible Form-in-Place Gasket Adhesive

Ultra Light-Weld® GA-142 is a UV/Visible light-curable form-in-place, cure-in-place gasketing material. This soft, sticky gasket adhesive is ideal for electrical enclosures, HVAC ductwork, and automotive casing applications which require low-compression set. GA-142 has good adhesion to plastic, metal, and also ceramic surfaces. Easily dispense the material into intricate and complex configurations with the benefit of curing in-line, which allows for increased production speed, greater output, lower processing costs, 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. Ultra Light-Weld® GA-142 is in full compliance with the RoHS2 Directives 2015/863/EU.


Durometer Hardness:  00-50

Compression Set % (85°C, 22 hr)* : 31

Substrates: Plastics (ABS, PC, PET, PP); Metals; Nylon 6/6

*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.
