    • Organopolysiloxane compositions of the present invention are the curable compositions of the addition curable type, which comprise (A) an organopolysiloxane having aliphatic unsaturated groups, (B) an organohydrogen polysiloxane having SiH groups, (C) a fluorine containing organopolysiloxane expressed by the following general chemical formula (1): ##STR1## wherein R.sup.1, R.sup.2, R.sup.4 through R.sup.6, and R.sup.8 are monovalent hydrocarbon groups such as alkyl groups, R.sup.3 and R.sup.7 are bivalent hydrocarbon groups, such as alkylene groups, Rf is either a perfluoroalkyl group or a perfluoroalkyl ether group, subscripts k, p, and m are integers of at least 1, and the subscript n is an integer of at least 0, and (D) a platinum group metallic catalyst. The cured products obtained from the compositions of the present invention exhibit a superior adhesiveness towards substances to be adhered, such as glass, aluminum, iron and epoxy resins.
    • 本发明的有机聚硅氧烷组合物是可加成固化型的可固化组合物,其包含(A)具有脂族不饱和基团的有机聚硅氧烷,(B)具有SiH基团的有机氢聚硅氧烷,(C)由以下通式表示的含氟有机聚硅氧烷 化学式(1):nd R8是一价烃基,例如烷基,R 3和R 7是二价烃基,例如亚烷基,R f是全氟烷基或全氟烷基醚基,下标k,p和m是 整数为1以上,下标n为0以上的整数,(D)铂族金属催化剂。 由本发明组合物获得的固化产物对玻璃,铝,铁和环氧树脂等粘合物质的粘附性显示出优异的表现。
