Abstract

An aqueous system comprises at least one epoxy resin and a reaction product with an amine equivalent weight of at least 50 prepared by the reaction of an (A) epoxy-functional amidoamine derived from at least one epoxy resin and an amidoamine obtained via the reaction of an acid-terminated polyalkylene glycol and a diamine in an active hydrogen:epoxy groups ratio of from 1:15 to 1:350, with (B) at least one polyamine in an active amine hydrogen:epoxy groups equivalent ratio of from 2:1 to 30:1, and, optionally (C) a monoepoxide in a remaining active amine hydrogen:epoxy groups equivalent ratio of from 5:1 to 20:1.
