Emseal AST Hi-Acrylic 12' 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 is suitable for use against metal, plastic, wood, concrete and other materials common in metal building structures.
