Ultra Light-Weld® Tack-Free, Moisture- and Chemical-Resistant FIP Gasketing Resin

Dymax GA-201 is a UV/Visible light-curable Form-In-Place/Cure-In-Place (FIP/CIP) Gasket formulated for sealing plastic enclosures, glass enclosures, metal enclosures, and plated surfaces for automotive door handle, appliance housing, and critical electronic assembly and device applications which require a soft, tack-free, flexible gasket. GA-201 gasketing material acts as a barrier to moisture to prevent absorption or penetration of air, dust, noise, liquids, gaseous substances, or dirt.

Dymax GA-201 gasketing resin can be dispensed into intricate and complex configurations with the added benefit of curing in-line which allows for increased production speed 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. This product is in full compliance with the RoHS2 Directives 2015/863/EU.


Durometer Hardness:  A35

Compression Set % (85°C, 22 hr)* :  26

Surfaces: Plastics; Glass; Aluminum; Stainless Steel; Plated Surfaces

*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.
