WATERPROOFING MEMBRANE

摘要

Disclosed is a waterproofing membrane that comprises a carrier sheet, a pressure sensitive adhesive layer on one surface of the carrier sheet, and a protective coating layer on the adhesive layer. The protective coating layer comprises a vinyl acetate copolymer (i.e., a copolymer of vinyl acetate and a comonomer) having a Tg of 10°C to 35°C. The protective coating layer protects the membrane against weather exposure, tolerates foot traffic and strongly adheres to concrete cast against it.
