Silicone compositions for making of cured release coatings.

摘要

This disclosure introduces silicone compositions that form cured release coatings which exhibit excellent release properties against tacky substances and which do not impair the residual adhesion of tacky substances. Our silicone composition comprises: (A) 100 weight parts of a coat-forming silicone composition into which there is admixed (B) 0.5 to 500 weight parts of an organosilicon polymer with the following average unit formula wherein R represents C1 to C10 monovalent hydrocarbon groups that are free of aliphatic unsaturation; R<1> represents organic groups selected from C2 to C20 alkylene groups or organic groups with the formulas -R<3>(OR<3>)y- and -R<3>-(R2SiO)zR2Si-R<3>-, R<3> denotes C2 to C20 alkylene groups which may be the same or different, y is an integer with a value of 1 or more, and z is zero or an integer with a value of 1 or more; R<2> represents groups selected from C1 to C10 monovalent hydrocarbon groups, the hydrogen atom, C1 to C10 alkoxy groups, and the hydroxyl group; n = 3 to 20; x = 1 to 13; and n >/= x.
