SILICONE-BASED ANTIFOULING COATING, ANTIFOULING FILM AND METHOD OF FORMING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a silicone-based antifouling coating which can suppress progress of time-related deterioration, compared with hardened products of time degradable coatings, and exert excellent antifouling performance by preventing adhesion of aquatic organisms for a long period and an antifouling film and a method of forming the film.SOLUTION: A coating for formation of a hard antifouling film consists of a mixed solution of an organic solvent capable of dissolving a time degradable coating which undergoes decomposition degradation with time after hardening or a hardened product of the coating and a hardenable silicone resin ingredient which hardens, through a cross-linking reaction, to a hard silicone resin having a branched chain- or network-like three-dimensional cross-linked structure and is used by adding a cross-linking agent for the hardenable silicone resin ingredient.
