The present disclosure describes cyclic carbonate-amine resin coating compositions including an amino functional silicon resin component, where the cyclic carbonate-amine resin coating displays improved oxidation resistance and durability. The coating compositions are isocyanate free and may be cured a low temperatures to provide a durable coating. In specific embodiments, the described coating compositions may be used as a mono-coat on a surface of an article, without any undercoating or primer layers.

Coating compositions comprising cyclic carbonate amine resins

A cationic electrodepositable coating composition is disclosed. The present invention in directed to a cationic electrodepositable coating composition comprising a lignin-containing cationic salt resin, that comprises (A) the reaction product of: lignin, an amine, and a carbonyl compound; (B) the reaction product of lignin, epichlorohydrin, and an amine; or (C) combinations thereof.

Cationic electrodepositable coating composition comprising lignin

A catalytic tin carboxylate adduct, which is useful as a catalyst in epoxy-acid coating compositions, is the reaction product of (A) a mono-, di-, or poly-carboxylic acid functional compound and (B) an organotin compound containing one to three aryl groups and at least one halogen or hydroxyl group attached to the tin atom. There is also provided an epoxy-acid coating composition, which incorporates this catalytic tin carboxylate adduct. The epoxy-acid coating composition is advantageous as an automotive topcoat, particularly as a clear coat composition because it exhibits good appearance, durability, stability and generates no, or extremely low levels of benzene during the curing process.
