<p>Diorganopolysiloxane release compositions, the release properties of which are modified by the incorporation of a copolymer of average general formula A3SiO(Me2SiO)x(MeRSiO)y(MeHSiO)zSiA3 where A and R are selected from specified groups x and z are numbers from 0-950, y is a number from 1 to 1000, x + y + z is not less than 20 and not greater than 1000, y/(x+y+z) is not less than 0.05 and the total ratio of R:Si in the composition is not less than 1:2000.</p> |
