PROBLEM TO BE SOLVED: To provide an antifouling paint composition which forms a coating film capable of preventing a living organism from adhering and growing on the surface of an underwater moving object or underwater structure for a long period of time. (A) A viscosity at 25 ° C. of 20 to 100. A diorganopolysiloxane having silanol groups at both ends of a molecular chain having a molecular weight of 10,000 mPa · s, (B) a general formula: R a SiX 4 -a (wherein R is a monovalent hydrocarbon group having 1 to 10 carbon atoms) , X is a hydrolyzable group, and a is an integer of 0 to 2. ) (C) an inorganic filler, (D) 25 ° C. Is from 10 to 10,000 mPa · s, (d− 1) A mixture of a diorganopolysiloxane fluid having a silanol group at one end of a molecular chain and a (d-2) non-reactive diorganopolysiloxane fluid [occupying in the component (D). The content of the component (d-1) is 2 to 20% by weight. And (E) a room-temperature-curable organopolysiloxane composition comprising a condensation reaction catalyst. |
