Patent ID: 7153581

Claim:
An abhesive coated substrate comprising paper, wood, cork, polymer film, woven fabric, or non-woven fabric, said abhesive coating comprising an extrudable, thermoplastic organic silicone copolymer, solid at 25° C. comprising: a) an organic polymer component comprising from 30 to 99% by weight, based on the total weight of components a) and b), of moieties derived from one or more monomers selected from the group consisting of vinylaromatics, (meth)acrylic esters of C 1-15 alcohols, vinyl esters of branched or unbranched C 1-15 alkylcarboxylic acids, olefins, dienes, and vinyl halides, and b) a silicone component comprising from 1 to 70% by weight, based on the total weight of components a) and b), of moieties derived from a mixture of at least two diorganopolysiloxanes having the general formula R 1 a R 3-a SiO(SiR 2 O) n SiR 3-a R 1 a , in which each R is identical or different and denotes a monovalent, optionally substituted, C 1-18 alkyl or C 1-18 alkoxy radical, R 1 denotes a polymerizable group, a is identical or different and denotes 0 or 1, at least one a being 1, and n is an integer, where b1) from 5 to 65% by weight of the silicone component b) is composed of one or more diorganopolysiloxanes with n≦30 and only one terminal polymerizable group R 1 , and b2) from 35 to 95% by weight of the silicone component b) is composed of one or more diorganopolysiloxanes with n≧55 and with one or two terminal polymerizable groups R 1 , wherein said abhesive coating is a water repellant hydrophobic coating.
