Tack-free gasket material
Intertronics has introduced a new tack-free, soft gasket material from sales partner, Dymax, for sealing fuel cells, appliance housings, and critical electronic assemblies and devices. Light Weld GA-140 is a UV/visible light-curable form-in-place (FIP) and cure-in-place (CIP) 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 plastics which provides a barrier to prevent absorption or penetration of air, dust, moisture, liquids and gaseous substances.
GA-140 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. It is a silicone-free, one-part resin requiring no mixing. It is low out-gassing, cures in seconds, and with a viscosity that allows for varying bead heights. It conforms to intricate channels or recesses and has excellent tear resistance for serviceable and limited-service applications.
Intertronics' experience across many industries confirms that the FIP gaskets cure completely in seconds even in 1/4in-thick beads. This eliminates the racking, stacking, waiting, and un-racking as required with traditional FIP gaskets. Light-curing FIP gaskets offer the ultimate in gasket design flexibility - designed for flat flanges or wide shallow grooves, permanent FIP gaskets can eliminate the delay experienced with slow-curing resins as well as the design, inventory, and labour expense associated with pre-cut gaskets.
