<p>A water miscible or soluble amine terminated resin useful as a curing agent comprising the reaction product of: A) a polyamine component comprising one or more hydrophilic amine terminated polyalkylene glycols, and optionally one or more hydrophobic polyamines; B) a polyepoxide component comprising one or more diglycidyl ethers of a polyalkylene glycol, one or more diglycidyl ethers of a cycloalkylene glycol and optionally one or more hydrophobic polyglycidyl ethers, wherein the mixture is optionally advanced by an amine extender; C) optionally, a reactive diluent which is capable of reacting with an epoxy resin; and D) optionally, a catalyst for the reaction of an amine with an epoxy resin; wherein Component A is employed in an equivalent excess with respect to Component B such that the terminal moieties of the reaction product are amine moieties capable of reacting with an epoxy resin; the composition has an amine hydroxy equivalent weight of from 140 to 240; and the composition is water soluble or water miscible. In preferred embodiments such amine terminated resin is an efficient pigment grinding vehicle. The aminate terminated resin can be dispersed in water with a polyepoxide to form a coating composition.</p> |
