Reactive systems and their use for the production of coatings, adhesives, sealants, castings or mouldings |
摘要 |
A reactive system contains an organic polyamine and a polyisocyanate reversibly blocked with a hydrocarbon resin having phenolic OH groups. A reactive system (I) comprises (A) a polyisocyanate component consisting of at least an organic polyisocyanate with reversible blocked isocyanate groups; (B) an organic polyamine having at least two primary amine groups; and optionally (C) oxirane group containing compounds. (A) has a molecular weight of 168-25000 (excluding blocking agent) and its isocyanate groups are reversibly blocked with a hydrocarbon resin having phenolic OH groups. |
