Title:
A PROCESS FOR PREPARING A TRIAZINE TRIS-LACTAM CROSSLINKING AGENT AND CURABLE COMPOSITIONS CONTAINING THE SAME
Document Type and Number:
WIPO Patent Application WO/1993/010117
Kind Code:
A1
Abstract:
A process for preparing a tris-lactam crosslinking agent, tris-pyrrolidonyl triazine, from N, N', N''-tris(4-chlorobutyryl)melamine by treatment of the chlorobutyryl derivative with a base such as sodium or potassium carbonate to effect intramolecular cyclization to the tris-lactam. A curable composition comprised of tris-pyrrolidonyl triazine as the crosslinking agent and a hydroxyfunctional or aminofunctional material as a resin. Thick films with no pinholes are prepared from the curable compositions using powder coating techniques.
