- Fits All Large Hot Melt Butyl Dispensers
CRL Hot Melt Butyl Insulating Glass Sealant is a 100 percent solids, hot applied butyl-based sealant designed to give tenacious adhesion to glass and aluminum, for a moisture-proof seal in I.G. units. The product is a one-component sealant system with lower moisture vapor transmission rates than current polysulfide, silicone, or polyurethane systems. It features low residual tack and excellent corner knitting. CRL Hot Melt Butyl applies with any hot melt pumping system, and is available in different forms for use with various system types. Chunk packaging is for larger dispensers, such as CRL Aztech Mini and Aztech II .
Hot melt butyl is dispensed at operating temperatures in excess of 400°F. Wear the proper safety gear including gloves, arm guards and protective eyewear to avoid burns and other injuries.
