Abstract
An adhesion composition comprising: PA0 (A) a high molecular weight fluorosilicone polymer containing the unit having the formula (1): EQU RfCH.sub.2 CH.sub.2 (CH.sub.3)SiO-- (1) PA0 wherein Rf is a perfluoroalkyl group containing 1 to 8 carbon atoms, in an amount of 30 mol % or more in the molecule, and blocked with the vinyl group at the both ends, PA0 (B) a low molecular fluorosilicone polymer containing the unit having the formula (1) in an amount of 30 mol % or more in the molecule, and containing an average of 3 or more units having the following formula (2): EQU CH.sub.2 .dbd.CH(CH.sub.3)SiO-- (2), PA0 (C) an organohydrogenpolysiloxane, PA0 (D) an organosilane or organopolysiloxane having at least one hydrogen atom or alkenyl group bonded to a silicon atom and having at least one of the oxirane group, dialkoxysilyl groups or trialkoxysilyl groups, and PA0 (E) a platinum catalyst. The cured product of the composition has good resistance to gasoline, and therefore useful for automobile parts.
