Gasket Sealant

GA-103

Moisture- and Chemical-Resistant Form-in-Place Gasket


Dymax GA-103 is a form-in-place, cure-in-place gasketing sealant formulated for fuel cells, underwater enclosures, and high-temperature sealing applications requiring a low compression set. GA-103 has good adhesion to plastics, electroplated plastics, and metal surfaces and exhibits superior heat, water, and chemical resistance.

 This silicone-free liquid gasket is one component and can be dispensed into intricate and complex configurations. Its ability to quickly cure in line with UV/Visible light helps improve production speeds, increase output, lower processing costs, and reduce inventories.

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.

This product is in full compliance with the RoHS2 Directives 2015/863/EU.

Property Values
Viscosity (nominal) 60,000 cP
Cured durometer hardness 00-75
Cured compression set (85°C, 22 hr.) * 14.9%
Recommended substrates Plastics; Electroplated 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.
