  • SUBSTRATES COATED WITH CLEAR POLYUREA FILM-FORMING COMPOSITIONS
    Publication number: 20110076485
    Abstract: The present invention is directed to substrates coated with a transparent or translucent film-forming composition, prepared from a curable, two-package composition comprising a first and second reactive package. The first reactive package contains a polyamine component comprising: i) a polyether functional polyamine; ii) an aspartic ester functional polyamine; and iii) an aliphatic polyamine. The second reactive package comprises a polyisocyanate, and the curable composition, under ambient conditions, upon mixing of the reactive packages, demonstrates a gel time of at least 2500 seconds.

  • Multi-component coatings that include polyurea coating layers
    Patent number: 7611772
    Abstract: A polyurea composition, a multi-component composite coating and articles formed therefrom, and methods of forming the same are disclosed. The coating composition is formed from a reaction mixture comprising an isocyanate-functional component and an amine-functional component. The ratio of equivalents of isocyanate groups to equivalents of amine groups is greater than 1 while the volume mixing ratio of the isocyanate-functional component to the amine-functional component is capable of being applied to a substrate at 1:1.
