Single-Component, General Purpose, Textured Polyurethane Sealant

TREMPRO® 626 is a one-part, medium modulus, gun-grade polyurethane sealant designed for use in many applications, including lap joints on semi-truck trailers, shipping containers, RV trailers, and rail cars. The unique natural texture of TREMPRO 626 also makes it an ideal perimeter sealant for window and door installation where texture complements the stucco façade.
