Designed for panel joints, lap sealing, metal-to-metal bonding, bedding non-porous components, and PEMB (Pre-Engineered Metal Building) panel joints, this versatile sealant serves as an excellent alternative to traditional butyl tape. Its gunnable formulation eliminates the need for preformed tape shapes while providing more consistent seal thickness and faster installation, particularly in complex joints and lap seal applications. It can also be applied between dissimilar metals to help prevent galvanic corrosion.
TREMPRO® JS-773+ provides excellent adhesion to a wide variety of metal substrates and finishes, including hot-dip galvanized steel, Galvalume®, Kynar® 500, stainless steel, PVDF, aluminum, and fiberglass. With no mixing required, it is ready for immediate application using conventional caulking equipment or standard pump systems, making it ideal for production-line fabrication and field installation.
