專業(yè)銷售EMSEAL密封膠
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.
