COATING RESIN COMPOSITION FOR CIVIL ENGINEERING AND CONSTRUCTION, CURED PRODUCT, CIVIL ENGINEERING AND CONSTRUCTION STRUCTURE, AND COATING METHOD FOR CIVIL ENGINEERING AND CONSTRUCTION STRUCTURE

摘要

To provide a coating resin composition for civil engineering and construction that can form a cured product having a sufficient work life and having an excellent performance of preventing exfoliation, and a coating method for a civil engineering and construction structure.SOLUTION: A coating resin composition for civil engineering and construction has a prepolymer having an isocyanato group (a), and a curing agent (b). The prepolymer (a) has an aliphatic polyisocyanate-derived structure and a polyol-derived structure. The curing agent (b) has at least one aliphatic polyamine selected from a linear aliphatic polyamine, a branched aliphatic polyamine, and an alicyclic polyamine having one or more primary amino group.SELECTED DRAWING: None
