(57) [Summary] [Structure] A primer composition comprising the following components (a), (b), (c) and (d) is applied in advance to a portion of the inorganic cured body or metal surface where repair is required, and then A method for repairing an inorganic cured body having a silicon alkoxide coating layer or a metal surface, which comprises applying an ordinary temperature curable inorganic coating material. (A) 100 parts by weight of an epoxy resin, (b) 10 to 500 parts by weight of an organosilicon compound having a mercapto group and 2 or more alkoxy groups, (c) an organosilicon compound 5 having an amino group and 2 or more alkoxy groups. ~ 200 parts by weight, (d) organic solvent. [Effect] It is possible to repair alkoxide-based silicone treated surfaces, stainless steel, cement, putty, color nails, etc. with excellent weather resistance and with little color change. |
