Light-Curable Form-in-Place Black Gasket Adhesive

Replace labor-intensive die-cut gaskets and slow-cure RTV sealants with Ultra Light-Weld® GA-108 form-in-place gasket adhesive that cures with UV/Visible light in seconds. GA-108 is ideal for electrical enclosures, HVAC ductwork, and automotive casing applications which require a soft, sticky, flexible gasket with low compression set. This black gasket material has good adhesion to plastic and metal, as well as ceramic surfaces. Easily dispense the resin into intricate and complex component configurations with the added benefit of curing in-line, increasing production speed and reducing 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-108 is in full compliance with the RoHS2 Directives 2015/863/EU.


Durometer Hardness:  00-65

Compression Set % (85°C, 22 hr)* : 41.1

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.
