Zusammenfassung: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.
