Abstract: The invention relates to a high temperature curable coating composition comprising: (a) at least one film-forming resin, (b) at least one crosslinker for the film-forming resin, wherein the crosslinker is not substantially reactive at temperatures under 120° C., and (c) an anticorrosive agent, which comprises a combination of a magnesium compound and a water-soluble Li salt. The invention further provides a method of coating a metal substrate and a coated metal substrate. The resulting coating has excellent anticorrosive properties without the use of Cr(VI) compounds, while being suitable for high temperature cure conditions typical in coil coatings.

Abstract: The current invention relates to a coating composition comprising a polyisocyanate compound, a hydroxyl-functional film-forming polymer, and a non-volatile branched monoalcohol. An aliphatic branched monoalcohol is preferred. More preferred are long chain non-volatile branched monoalcohols. This results in coating compositions that have improved flow behavior and that produce coatings having improved appearance without an adverse effect on other properties. The invention also relates to a multi-component coating composition. Preferably, the multi-component coating composition is a two-component coating composition comprising a polyisocyanate component and a hydroxyl-functional component, wherein the hydroxyl-functional component, in addition to the hydroxyl-functional film forming polymer also comprises the non-volatile branched monoalcohol.

Abstract: The present invention relates to a film forming composition, a method of forming the composition, and application of the composition to coating formulations which provide a cured coating having acid rain resistance. A film-forming polyurethane polyol composition comprises a reaction product of an n-functional isocyanate (wherein n is a number ranging from about 2 to about 5) with at least one diol or triol or mixtures thereof and a compound containing isocyanate-reactive functional groups, preferably a monofunctional alcohol or thiol. The low viscosity polyurethane polyol of the present invention is typically crosslinked/cured using a melamine to produce a cured coating which is highly acid etch resistant as well as having other desirable physical-mechanical properties. The coating compositions have improved flow characteristics compared to compositions containing polyurethane polyols prepared without the monofunctional alcohols or thiols.
