Patent ID: 7695818

Claim:
A double-sided tape comprising a) a substrate having a first major surface and a second major surface opposite the first major surface; b) a pressure sensitive adhesive layer disposed on the first major surface of the substrate, the pressure sensitive adhesive layer comprising a pressure sensitive adhesive composition comprising 1) a silicone tackifying resin; 2) a polydiorganosiloxane polyurea copolymer that is the reaction product of a polydiorganosiloxane polyamine and a polyisocyanate; and 3) a permanent plasticizer chosen from the group consisting of: glycol ethers, esters, alcohols, hydrocarbons, ketones, amines and oils wherein the silicone tackifying resin is present in an amount of at least about 55 wt-% based on the weight of the silicone tackifying resin and the polydiorganosiloxane polyurea copolymer and wherein the plasticizer is present in an amount to provide a generally uniform distribution of the polydiorganosiloxane polyurea copolymer and the silicone tackifying resin; and c) a second adhesive layer disposed on the second major surface of the substrate, wherein the second adhesive is acrylic based.
