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.
La presente invención se dirige a substratos revestidos con una composición formadora de película transparente o translúcida, preparada a partir de una composición curable, de dos paquetes que comprende un primer y segundo paquetes reactivos. El primer paquete reactivo contiene un componente poliamina que comprende: i) una poliamina poliéter funcional;ii) una poliamina éster aspártico funcional; y iii) una poliamina alifática. El segundo paquete reactivo comprende un poliisocianato, y la composición curable, bajo condiciones ambiente, al mezclar los paquetes reactivos, demuestra un tiempo de gelificación de al menos 2500 segundos. |
