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.
- Will not dry out and become hard or brittle
- The seals are UV-stable and highly resistant to aging and vermin (bugs, rodents, birds, etc.)
- Will not extrude from between joints when squeezed, which is a possibility with caulk or butyl-type tapes
- May be used in non-moving gasket-type applications as well as in moving expansion/contraction-type joints.
Dimensions: 1" x 12' roll
