摘要：
in which each R'', which may be identical or different, represents an alkyl group with 1 to 5 carbon atoms or a vinyl group, n is zero or 1 and R is as defined above and 5 to 25 parts of an organic derivative of titanium which is selected from an alkyl polytitanate, which is soluble in hydrocarbon solvents, having the average general formula TibOc(OR'''')d in which R'''' represents an alkyl group with 3 to 8 carbon atoms, b represents an integer of at least 2, c represents an integer of at least 1 and d represents an integer of at least 4, and a mixture consisting of at least 5 percent of a said aklyl polytitanate with an alkyl titanate, the alkyl group having 3 to 10 carbon atoms, and/or a titanium chelate.
Non-stick coating compositions are provided which are capable of being applied to a very wide range of substrates and which are stable in the atmosphere for 24 hours, the compositions being based on a dimethylpolysiloxane polymer and containing, per 100 parts by weight of the polymer, 1 to 15 parts of a silicate ester which is selected from an alkoxyalkyl silicate of the formula: Si((OCH2CH2)aOR)4 in which R represents an alkyl radical with 1 to 4 carbon atoms and a is 1 or 2, and a cyclic silicate of the formula:
