摘要:
The present invention provides a film-forming composition. The composition includes a reaction product of: a) a polyamine containing a primary amino group and a secondary amino group; and b) an acyclic carbonate. Also provided is a method of preparing a film-forming composition and an article coated with such compositions.
摘要:
Product obtained from the reaction of(a) an amine-diol resulting from the reaction of a primary amine having the formula R-NH.sub.2 in which R represents an aliphatic or aromatic radical, with at least one alkylene oxide comprising predominantly propylene oxide, and(b) at least one polyfunctional substance, capable of acting on the hydroxyl groups of said amine-diol.The product disclosed may be used as an additive in an electrodeposition paint composition in order to furnish, after application to a metal substrate, a coating or film having an improved resistance to pinholes and to cratering.
