摘要

1279786 Fluoroalkyl acyloxy siloxanes DOW CORNING CORP 19 April 1971 [20 April 1970] 21024/71 Headings C3S and C3T Novel compounds of the formula wherein at least one X denotes a radical -CH 2 CH 2 Si(O.COCH 3 ) 3 and the remainder denote hydrogen or a radical -CH 2 CH 2 Si- (O.COCH 3 ) 3 , are prepared by reacting appropriate stoichiometric quantities of vinyltriacetoxysilane and tris-(dimethylhydrogensiloxy)- 3,3,3-trifluoropropylsilane in presence of a chloroplatinic acid catalyst. Uses.-As primers in adhering silicone elastomers, particularly those based on poly-3,3,3- trifluoropropylmethylsiloxane to titanium, and as components in primer compositions also comprising organic solvent, tetrabutyltitanate and ethylpolysilicate, for use in adhering silicone elastomers to polyurethanes and epoxy resins.
