Claims
- 1. A coating composition comprising only non-hydroxy functional resin and consisting essentially of
- a) a secondary amine reactive diluent, and
- b) aldimine having the formula ##STR6## wherein n averages greater than 1,
- R.sub.1 is alkyl, aryl, cycloaliphatic or substituted alkyl, aryl, cycloaliphatic or heterocyclic group, and R.sub.2 is monomeric or polymeric aliphatic, aromatic, arylaliphatic or cycloaliphatic group which may contain O, N, S, or Si,
- c) an isocyanate compound having uretedione functionality,
- d) at least one moisture absorbing compound, and
