Abstract
A method for repairing and lustering defects on a hydrophilic coat surface is reported. The method comprises the steps of applying a buffing composition on a hydrophilic coat surface; and buffing the hydrophilic coat surface to which the buffing composition has been applied. The buffing composition is an aqueous composition which comprises water and a water-soluble high-boiling-point liquid organic compound, and further comprises either a combination of abrasive particles and a dispersant, or lustering agent, or the both. The method allows for the removal of defects on a hydrophilic coat surface with good finish after repairing and without deteriorizing the antifouling function of the hydrophilic coat against urban fouling substances.
Claims6
A method for repairing and lustering defects on a hydrophilic coat surface, comprising the steps of:
- (a) applying a buffing composition on a hydrophilic coat surface, said buffing composition comprising:
- water;
- a water-soluble high-boiling-point liquid organic compound having a carbon number of 3 to 12;
- and
- either (i) a combination of abrasive particles and a dispersant;
- (ii) a lustering agent, or both (I) and (ii);
- and
- (b) buffing the hydrophilic coat surface to which the buffing composition has been applied, wherein the water-soluble high-boiling-point liquid organic compound is not dried during the buffing step.
