Coating composition for repairing concrete crack, coating liquid and coating film containing the coating composition, and manufacturing method of the coating film

摘要

Problem to be solved: to provide a practical coating composition for easily repairing cracks generated in concrete and a coating liquid made of these compositions.Solution: (a) coating composition for concrete crack repair containing (a) stearic acid: 1 to 3% by weight, (b) petroleum base oil: 30 to 40% by weight, (c) vegetable oil fat: 3 to 6% by weight and (d) modified silicon: 50 to 70% by weight.(however, the total amount of stearic acid, (b) petroleum based oil, (c) vegetable oil and (d) modified silicon is 100% by weight)The coating composition of the present invention is excellent in permeability and adhesion to concrete cracks, and has a waterproof and acid resistant surface property and can form a highly durable coating film.No selection
