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 carboxyfunctional resins.
