Disclosed is a polyurethane material useful in coating compositions that can and may be applied to a substrate by electrodeposition and non-electrodeposition coating methods. Polyurethane materials, coatings prepared therefrom, and methods of making them are provided. The polyurethane material comprises 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, as well as other materials from which the polyurethane material is formed. It can be formed from a component comprising at least one acid functional material or anhydride having a functional group that is reactive with the isocyanate or hydroxyl group of the component. The polyurethane can provide improved physical properties (eg, abrasion resistance) when incorporated into a coating composition. [Selection figure] None |
