Tremco will debut its new sealant, the EnerSEAL 340R. The product is a reactive, warm-applied sealant. The modified polyurethane insulating glass perimeter barrier sealant combines the ease of handling and speed of a single-component hot melt with the shear and heat resistance of a reactive polyurethane. EnerSEAL 340R has excellent adhesion to glass, say officials, foam spacer barrier films, plus aluminum, plated-steel, stainless-steel and composite IG spacers. Booth #3207
