Abstract
A polyurethane material, the coatings prepared therefrom, and methods of making the same are provided. A polyurethane material may be formed from components comprising at least one polyisocyanate, at least one active hydrogen-containing material, at least one material having at least one primary or secondary amino group and at least one hydroxyl group, and at least one acid functional material or anhydride having a functional group reactive with isocyanate or hydroxyl groups of other components from which the polyurethane material is formed. The polyurethane can provide improved physical properties, such as chip resistance, when incorporated into a coating composition.
