ABSTRACT:
A high solids coating composition suitable for use, for example, as a high performance automotive coating is provided, which comprises (1) a particular polyurethane polyol which is the reaction product of an symmetric 1,3-diol component and an isocyanate component, and (2) an hydroxyl group-reactive crosslinking agent. When formulated as a one-pack coating preferably with an aminoplast crosslinking agent, these coating compositions possess a number of desirable properties including excellent acid etch resistance.
