PURPOSE: A polyester paint composition for anti-fouling PCM(pre-coated metal) outer surface having contamination- and acid-resistance and excellent self-cleaning ability is provided by applying polysilicate in an effective amount as a surface modifier into a paint composition for PCM having a polyester resin and melamine resin as principal substances. CONSTITUTION: In a polyester paint composition for anti-fouling PCM outer surface containing hydroxyl unsaturated polyester resin, melamine resin, hardening promoter, co-promoter and hardening catalyst, a silicate surface modifier represented by following chemical formula I is characteristically included in an amount of 1wt%-15wt% in the whole composition. In the chemical formula I, R1, R2, R3, R4, R5, R6 represent hydrogen, methyl group or ethyl group and they can be same or different. |
