Abstract:
[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 R2OH elimination reaction of: (B1) an organopolysiloxane represented by: (R2O)((R2O)2SiO)n-1Si(OR2)3 wherein n is an integer of 2 or more and R2 each is independently a monovalent hydrocarbon group, and (B2) an organopolysiloxane having at least one structure represented by: ≡SiR3OH wherein R3 is a divalent hydrocarbon group, in a molecule.
