Abstract: An adhesion promoting composition includes a polymer, such as an acrylic copolymer, having acetoacetoxy functionality and adhesion-promoting functionality and a metal alkoxide, chelate, and/or alkoxide chelate. The composition is applied in a first layer over a metal substrate or a coated substrate, then coated with a desired refinish coating composition.

Abstract: A coating composition includes a polyurethane polyol and a cross-linking agent. The coating composition is used in original equipment manufacturer (OEM) coating industries. The polyurethane polyol includes the reaction product of an isocyanate component and a first compound having at least two hydroxyl groups. The two hydroxyl groups of the first compound are separated by at least four carbon atoms. The separation of the two hydroxyl groups of the first compound allows the first compound to react with an amount of the isocyanate required to facilitate drying of the coating composition and reduce a chance that contaminants may settle into the coating composition.
