Study on Application Effect of Latent Curing Agent in Single Component Polyurethane Waterproofing Coating
In this article,the effects of different types of latent curing agents on the defoaming effect,mechanical properties and storage stability of single component polyurethane waterproofing coating are studied.The results show that all the different types of latent curing agents can effectively defoam;aldimine based latent curing agents have little adverse effect on the mechanical properties of the coating,but oxazolidine based latent curing agents can significantly reduce the mechanical properties of the coating;aldimine based latent curing agents,of which the molecular structures do not contain groups that react with isocyanates or trigger other reactions,have no negative effect on the storage stability of the coating.
