A curable fluorosilicone resin composition is disclosed, which composition comprises (A) 100 parts by weight of a fluorosilicone resin consisting essentially of F(CF2)aCH2CH2SiO3/2) siloxane units and, optionally, RbSiO(4-b)/2 siloxane units, wherein R is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms, a is an integer with a value of at least 4 and b is an integer with a value of 0 to 3, with the proviso that when said fluorosilicone resin contains said RbSiO(4-b)/2 siloxane units, the ratio of said F(CF2)aCH2CH2SiO3/2 siloxane units to said RbSiO(4-b)/2 siloxane units is at least 1; (B) 1 to 90 parts by weight of a component selected from the group consisting of an organosilane and its partial hydrolysis product, said organosilane having the general formula R1cSiX4-c wherein R1 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms, c is 0, 1, or 2 and X is a hydrolyzable group; and (c) a sufficient amount of a condensation catalyst to accelerate the cure of said fluorosilicone resin composition.
