    摘要： 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.
