EMSEAL AST Hi-Acrylic Closure Sealant Tape

AST is a self-adhering tape seal made from resilient, open-cell polyurethane foam impregnated with a water-based acrylic-modified asphalt emulsion. It replaces and outperforms liquid and butyl tape sealant and closed-cell closures.

AST sealant tapes are preformed, resilient, self-adhesive, expanding tape seals made from an open-cell foam that has been impregnated with a water-based, acrylic-modified asphalt emulsion and then compressed to a sealing density level appropriate to the application. Typically, higher compression levels are required for water-tightness in water run-off applications; lower compression can be used, for example, for snow seals at roof ridges.
