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.

1. A curable composition comprising components: a) at least one aliphatic polyisocyanate;b) at least one aliphatic polyamine; andc) 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, andn represents an integer ≧1. 2. The curable composition of claim 1, wherein Z represents —CH2OH or —C(═O)OCH2CH2OCH2CH2OCH2CH2OC(═O)—. 3. The curable composition of claim 1, wherein said at least one aliphatic polyamine comprises an aspartic ester. 4. The curable composition of claim 1, wherein said at least one aliphatic polyamine includes an aliphatic polyamine represented by the formula wherein R1 and R2 independently represent an alkyl group having 1 to 10 carbon atoms, and R3, R4, R5, and R6 independently represent hydrogen or an alkyl group having 1 to 5 carbon atoms. 5. The curable composition of claim 4, wherein R1 and R2 are independently alkyl groups comprising at least 2 carbon atoms. 6. The curable composition of claim 1, wherein each said at least one aliphatic polyamine has the general formula: wherein R7 and R8 independently represent an alkyl group having from 1 to 10 carbon atoms, or a cyanoalkyl group having from 1 to 10 carbon atoms, and wherein R9, R10, and R11 are independently hydrogen or an alkyl group having from 1 to 5 carbon atoms. 7. The curable composition of claim 1, wherein the at least one aliphatic polyisocyanate comprises a trimer of 1,6-hexanediisocyanate. 8. 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; andc) 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, andn represents an integer ≧1. 9. The method of claim 8, wherein Z represents —CH2OH or —C(═O)OCH2CH2OCH2CH2OCH2CH2OC(═O)—. 10. The method of claim 8, wherein said at least one aliphatic polyamine comprises an aspartic ester. 11. The method of claim 8, wherein said at least one aliphatic polyamine includes an aliphatic polyamine represented by the general formula wherein R1 and R2 independently represent an alkyl group having 1 to 10 carbon atoms, and R3, R4, R5, and R6 independently represent hydrogen or an alkyl group having 1 to 5 carbon atoms. 12. The method of claim 8, wherein each said at least one aliphatic polyamine has the general formula: wherein R7 and R8 independently represent an alkyl group having from 1 to 10 carbon atoms, or a cyanoalkyl group having from 1 to 10 carbon atoms, and wherein R9, R10, and R11 are independently hydrogen or an alkyl group having from 1 to 5 carbon atoms. 13. The method of claim 8, wherein the at least one aliphatic polyisocyanate comprises a trimer of 1,6-hexanediisocyanate. 14. 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; andc) 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, andn represents an integer ≧1. 15. The composite article of claim 14, wherein Z represents —CH2OH or —C(—O)OCH2CH2OCH2CH2OCH2CH2OC(═O)—. 16. The composite article of claim 14, wherein said at least one aliphatic polyamine comprises an aspartic ester. 17. The composite article of claim 14, wherein said at least one aliphatic polyamine includes an aliphatic polyamine represented by the general formula wherein R1 and R2 independently represent an alkyl group having 1 to 10 carbon atoms, and R3, R4, R5, and R6 independently represent hydrogen or an alkyl group having 1 to 5 carbon atoms. 18. The composite article of claim 14, wherein each said at least one aliphatic polyamine has the general formula: wherein R7 and R8 independently represent an alkyl group having from 1 to 10 carbon atoms, or a cyanoalkyl group having from 1 to 10 carbon atoms, and wherein R9, R10, and R11 are independently hydrogen or an alkyl group having from 1 to 5 carbon atoms. 19. The composite article of claim 14, wherein the at least one aliphatic polyisocyanate comprises a trimer of 1,6-hexanediisocyanate.
