The use of cyclamic acid as a catalyst for the curing of hydroxyl-functional resins having a functionality greater than 2 provides a wrinkle finish. The hydroxy-function may be present in polyesters, epoxies, and acrylate or methacrylate resins, among others. The polyester resins which are able to provide such a finish have a hot plate melt flow of from about 20 mm to about 150 mm.
'utilisation de l'acide cyclamique comme catalyseur pour le durcissement des résines à groupement fonctionnel hydroxyle ayant une fonctionnalité supérieure à 2 donne un fini ridé. La fonction hydroxy peut être présente, entre autres, dans les résines de polyester, d'époxy et d'acrylate ou de méthacrylate. Les résines de polyester qui sont capables de fournir un tel fini ont un indice de fluage sur plaque chauffante variant entre environ 20 mm et environ 150 mm.
