Abstract
A non-toxic antifouling coating composition comprising (a) about from 5 to 95 parts by weight as the resin solid content of a room temperature-curable silicone rubber having a number-average molecular weight of about from 20,000 to 100,000, (b) about from 5 to 95 parts by weight as the resin solid content of a room temperature-curable silicone rubber having a number-average molecular weight of about from 500 to 20,000, (c) silicone oil in an amount of about from 20 to 200 parts by weight per 100 parts by weight of the total solids of the rubbers (a) and (b), and (d) hydrophobic fumed silica in an amount of about from 5 to 30 parts by weight per 100 parts by weight of the total solids of the rubbers (a) and (b), provides a non-toxic antifouling coating composition which is capable for forming a coating film having highly improved antifouling properties and antifouling durability for a long period of time.
