Gasketing resin for plastics

Intertronics has introduced a tack-free, soft gasket material for sealing fuel cells, appliance housings, and electronic assemblies and devices.

Light Weld GA-140 is described as an ultra-violet/visible light-curable form-in-place and cure-in-place gasket developed by the company's sales partner, Dymax, for applications requiring low compression set, tack-free surface, and durable sealing. "It is a soft gasket material with high adhesion to plastics which provides a barrier to prevent absorption or penetration of air, dust, moisture, liquids, and gaseous substances", says Peter Swanson, Intertronics.

"GA-140 can be dispensed into intricate and complex configurations with the benefit of in-line curing. It is a silicone-free, one-part resin that does not require mixing. It is low out-gassing, cures in seconds, and has a viscosity that allows for varying bead heights."
