Compositions capable of being cured under UV, comprising a photoinitiator and the product of the reaction of an alpha , omega -dihydroxypolydimethylorganosiloxane oil and of a hydroxylated polysiloxane resin with a silane of formula CHX=C(R')COO=G-Si(Ra)Q3-a or formula: HS-G-Si(Ra)Q3-a, in which formulae: - G is a C1-C8 alkylene group, - R' is a hydrogen or methyl group, - R is a C1-C4 alkyl group, - X is a hydrogen group or a phenyl group, - Q is a C1-C8 alkoxy group, - A is 0, 1 or 2. Use of this composition as a thin layer for antiadhesive paper, but also as a thick layer for sheathing optical fibres or protection of printed circuits in electronics. |
