Abstract
A curable composition includes: a) at least one aliphatic polyisocyanate; b) at least one aliphatic polyamine; and c) from 8 to 17 percent by weight of at least one liquid compound, based on the total weight of components a), b) and c) combined. Each liquid compound is independently represented by the formula (I): wherein Z represents an n valent organic group, and n represents an integer ≧1. Methods of coating the curable coating on a substrate and composite articles are also disclosed.
