Claim 0:
1. A waterproof and weatherproof pressure sensitive adhesive tape comprising:
a. a substrate layer;
b. a co-binding layer comprising a polyorganosiloxane on one or both sides of the substrate layer to be coated with a pressure sensitive adhesive layer; and
c. the pressure sensitive adhesive layer contiguous with the co-binding layer comprising a crosslinker and an acrylate, terminated with a reactable group comprising a hydroxyl group that is obtained by reacting the acrylate with a superheated partially ionized steam in the presence of a catalyst after the coating of the substrate layer, wherein the hydroxyl group of the acrylate impregnates the pressure sensitive adhesive layer to solidify a pressure sensitive adhesive composition of the pressure sensitive adhesive layer.
