Abstract
The invention provides coating compositions comprising a reactive component (a) which is substantially free of any heteratoms and is a not a crystalline solid at room temperature and which comprises from (i) 12 to 72 carbon atoms, and (ii) at least two functional groups, and (b) a crosslinking agent comprising a plurality of functional groups (iii) reactive with the functional groups (ii) of compound (a), wherein functional groups (ii) and (iii) are selected such that reaction there between produces a thermally irreversible chemical linkage. The coating compositions of the invention provide improved solids, chip resistance, flexibility and/or scratch & mar resistance while maintaining desirable and/or improved performance characteristics with regard to environmental etch, relative humidity, QCT, chip resistance, thermoshock resistance, cold crack resistance, adhesion and the like.
