According to the present invention, the chelating agent contained in the curing agent composition is stable and does not react with the polyisocyanate for a predetermined period of time practically required.
In addition, the metal element and the metal chelating compound of the reaction promoter contained in the main composition of the coating composition or the adhesive composition can be produced. Therefore, when the main agent composition and the curing agent composition are mixed, the metal element of the reaction accelerator is temporarily masked by the chelating agent, and the crosslinking reaction by isocyanate can be delayed. That is, the pot life of the composition of the present invention is extended. When the coating composition of the present invention is coated on an object to be coated, the chelating agent is desorbed from the metal chelate compound produced by mixing the two liquids, for example, by evaporation, and the metal of the accelerator which has been temporarily masked until then. Since the element is exposed, the crosslinking reaction is promoted. As a result, the coating film of the coating composition is rapidly cured. That is, the pot life can be extended without inhibiting the curing rate of the composition. Further, in particular, when a coloring material containing a metal element is blended in the main component composition of the coating composition, the present invention in which a chelating agent is blended in the polyisocyanate is a metal element in the coloring material. Since the chelating agent can prevent the metal chelating compound from being generated and consuming the chelating agent, special advantages such as stabilizing the pot life while keeping the compounding amount of the chelating agent low are generated. .. Furthermore, the coating composition and the adhesive composition of the present invention have excellent performance for coating and adhering wood, plastics, metals and the like.
