Provided is a sealer coat composition for a nontoxic silicone antifouling paint which improves the adhesive strength and mechanical strength of an antifouling paint. The sealer coat composition comprises 100 parts by weight of a binder; 1-20 parts by weight of a resin for improving adhesion; 1-30 parts by weight of a curing agent; 0.01-30 parts by weight of a curing accelerator; 1-20 parts by weight of a coating reinforcing agent; and 1-20 parts by weight of an adhesion enhancer. Preferably the binder is represented by the formula(1) and has a number average molecular weight of 1,000-150,000 and a hardness of 40-120, wherein m is an integer of 30-2,000; R is H, OH, a linear or branched alkyl group, an alkoxy group, an acid group, a cyano group, an amino group or an epoxy group; R1 are identical or different one another and are H, OH, a C1-C4 linear or branched alkyl group, an alkoxy group, an aryl group or an organic residue containing F. |
