Gasket Sealant

GA-120

Light-Curable, Self-Leveling Form-in-Place Gasket


Dymax GA-120 gasket sealant forms and then cures in place upon exposure to UV/Visible light to help speed up production speeds and increase throughput. The material is designed for speaker assembly, sound damping, and automotive enclosure applications, features a self-leveling viscosity, and forms a soft, tacky, flexible gasket with good deflection.

This liquid gasket exhibits good adhesion to nylons and metal surfaces and dispenses easily into intricate and complex configurations. GA-120 is silicone- and solvent-free and one-component, making it a good choice for environmentally conscious manufacturers.

Dymax materials have no solvents added 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.

GA-120 is in full compliance with the RoHS2 Directives 2015/863/EU.

Property Values
Viscosity (nominal) 1,000 cP
Cured durometer hardness 00-50
Cured compression set (85°C, 22 hr.) * 0.17%
Recommended 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.
