| abstract |
The present invention relates to the use, as an anti-adherent and / or water-repellent, of grafted functionalized polyorganosiloxanes consisting of grafted copolymer units derived from at least one ethylenically unsaturated monomer capable of radical polymerization and of a polyorganosiloxane. functionalized containing similar or different units of formula (I): Ra Yb Xc Si O (4-abc) / 2 (I) formula in which: R = C1 -C18 alkyl, X = epoxyfunctional residue C1 -C20 alkylated, Y = acrylate, and a, b, c = 0.1, 2 or 3 with a + b + c = 0, 1, 2 or 3. These grafted functionalized POSs are used in the form of an aqueous dispersion for the production of a non-stick coating on a solid support, preferably chosen from sheets of polymer material or of paper, cardboard or the like, from adhesive tapes on their non-adhesive face, from interlayer films of double-sided adhesive tapes or from supports fibrous woven or not and / or co mposites or not. |
