Title
(EN) METHODS OF PREPARING COATED SUBSTRATES AND NON-AQUEOUS, CURABLE FILM-FORMING COMPOSITIONS USED THEREFOR
(FR) PROCÉDÉS DE PRÉPARATION DE SUBSTRATS REVÊTUS ET COMPOSITIONS FILMOGÈNES DURCISSABLES NON AQUEUSES S’Y RAPPORTANT
Abstract
(EN) The present invention is directed to non-aqueous, curable film-forming compositions comprising: a) an anhydride functional compound; b) at least one of: (i) a hydroxyl functional compound having at least two hydroxyl functional groups and (ii) a carbodiimide functional compound; and c) hydrolyzable functional groups. After application of the curable film-forming composition to a substrate to form a coated substrate, and upon subjecting the coated substrate to curing conditions, the curable film-forming composition undergoes multiple cure reactions. The present invention is further directed to methods of preparing coated substrates with these compositions.
(FR) La présente invention concerne des compositions filmogènes durcissables non aqueuses comprenant : a) un composé à fonctionnalité anhydride ; b) au moins l’un parmi : (i) un composé à fonctionnalité hydroxyle ayant au moins deux groupes à fonctionnalité hydroxyle et (ii) un composé à fonctionnalité carbodiimide ; et c) des groupes fonctionnels hydrolysables. Après application de la composition filmogène durcissable sur un substrat pour former un substrat revêtu et après que le substrat revêtu a été soumis à des conditions de durcissement, la composition filmogène durcissable subit plusieurs réactions de durcissement. La présente invention porte en outre sur des procédés de préparation de substrats revêtus à l’aide de ces compositions.
