Moisture-resistant gasketing is light curable

Ultra Light-Weld GA-111 from Dymax is a UV/visible light-curable form-in-place (FIP) gasket developed for applications requiring low compression set, tack-free surface, and durable, reliable sealing. It is a soft gasket material with high adhesion to metals while providing a barrier to prevent absorption or penetration of air, dust, moisture, liquids and gaseous substances. "This material can be dispensed into intricate and complex configurations with the benefit of in-line curing which allows for increased production speed, greater output, lower processing costs, and reduced inventories," explained Intertronics managing director Peter Swanson. Being a one-part resin, the material requires no mixing. "It is low out-gassing, cures in seconds, and its viscosity allows for varying bead heights," advised Swanson. "This is an exceptional advantage in so many of the UK's technologically advanced manufacturing industries." Light-curing FIP gaskets offer flexibility in gasket design as they cure completely in seconds even in 6mm thick beads. This removes the need for racking, stacking, waiting, and un-racking as required with traditional FIP gaskets.
