摘要

[PROBLEM TO BE SOLVED] To provide an organopolysiloxane paint composition capable of forming an antifouling coating film having an excellent long-term antifouling property. [SOLUTION] A curable composition obtained by mixing:
(A) 100 parts by weight of a reaction curable silicone rubber with:
(B) 1 to 100 parts by weight of an organopolysiloxane mixture including a product obtained by an R 2 OH elimination reaction of:
(B1) an organopolysiloxane represented by:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(R 2 O)((R 2 O) 2 SiO) n-1 Si(OR 2 ) 3
wherein n is an integer of 2 or more and R 2 each is independently a monovalent hydrocarbon group, and
(B2) an organopolysiloxane having at least one structure represented by:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ‰¡SiR 3 OH
wherein R 3 is a divalent hydrocarbon group, in a molecule.
