3M 7100028366 Foam Insulation Spray Adhesive 78 Ht

Product Description

The 3M 7100028366 is an industrial-grade, high-temperature spray adhesive engineered for bonding polystyrene foam and roofing membrane materials in demanding construction and insulation applications. Sold as the 3M Scotch-Weld Hi-Temperature Polystyrene Foam Insulation 78 HT, this adhesive delivers a strong, heat-resistant bond with a long open time that allows for accurate positioning of large panels before the bond sets. The pre-pressurized canister design provides a maintenance-free delivery system, eliminating the need for separate spray equipment on the job site. It is well suited for contractors and insulation professionals who require consistent adhesive coverage across wide surface areas.

This adhesive is intended for commercial and industrial roofing projects and insulation panel installations where polystyrene foam boards must be bonded to substrates or where roofing membranes require adhesive attachment. The high-temperature resistance makes it appropriate for roofing assemblies exposed to elevated ambient and surface temperatures. Insulation contractors, commercial roofers, and building envelope specialists are the primary installers of this product.
