Abstract: This invention relates to coating compositions comprising at least one aminoplast crosslinker resin A, binder resins B that have active hydrogen functionality, and a catalyst composition C, wherein the catalyst composition C is a mixture of an organic sulfonic acid C1, and an amine C2 which may be primary, secondary, or tertiary, and which must have a pKa value of not more than 10, and preferably not less than 4, a process for the preparation thereof, and to a method of use thereof.

Abstract: This invention relates to a process to make a reaction product UA of at least one multifunctional aldehyde A with at least one cyclic urea U, by mixing the at least one multifunctional aldehyde A with the at least one cyclic urea U in the presence of at least one alcohol R1—OH, and optionally, at least one solvent that has no reactive groups which may react with aldehyde groups, —CO—NH— groups, or hydroxyl groups, to effect an addition reaction to obtain a solution of a product UA, where R1 is selected from the group consisting of linear, branched or cyclic alkyl groups having from one to twelve carbon atoms, to the reaction product obtained by this process, and to a method of use thereof as crosslinker for coating compositions.

Abstract: Sulfonimide cure catalysts are used with aminoplast crosslinking agents and resins capable of reacting with aminoplast crosslinking agents to prepare heat curable compositions capable of crosslinking to form coatings and articles. Liquid or solid curable compositions may be prepared. Solid sulfonimide catalysts used in combination with solid glycoluril type crosslinking agents are well suited for powder coating systems containing hydroxy- and carboxy-functional resins.
