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.

- 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, wherein each compound of said at least one liquid compound is independently represented by the formula:
- wherein Z represents an n valent organic group, and
- n represents an integer ≧1.
A method of coating a substrate, the method comprising coating a curable composition onto a surface of a substrate, and at least partially curing the curable composition, wherein the curable composition comprises components:
- 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, wherein each compound of said at least one liquid compound is independently represented by the formula:
- wherein Z represents an n valent organic group, and
- n represents an integer ≧1.
A composite article comprising a coating disposed on a substrate, wherein the coating is prepared from components comprising:
- 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, wherein each compound of said at least one liquid compound is independently represented by the formula:
- wherein Z represents an n valent organic group, and
- n represents an integer ≧1.
