COATING RESIN COMPOSITION FOR CIVIL ENGINEERING AND CONSTRUCTION, CURED PRODUCT, CIVIL ENGINEERING AND CONSTRUCTION STRUCTURE, AND COATING METHOD FOR CIVIL ENGINEERING AND CONSTRUCTION STRUCTURE
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
【課題】十分な可使時間を有し、はく落防止性能に優れる硬化物を形成することが可能な土木建築用コーティング樹脂組成物、及び土木建築構造物のコーティング方法を提供すること。【解決手段】イソシアナト基を有するプレポリマー（ａ）と、硬化剤（ｂ）とを含み、プレポリマー（ａ）が、脂肪族ポリイソシアネート由来の構造及びポリオール由来の構造を有し、硬化剤（ｂ）が、直鎖状の脂肪族ポリアミン、分岐状の脂肪族ポリアミン、及び１級アミノ基を１つ以上有する脂環ポリアミンからなる群より選ばれる少なくとも１種の脂肪族ポリアミンを含有する、土木建築用コーティング樹脂組成物を提供する。【選択図】なし
