Ether amine compositions and coatings
The present technology relates generally to aqueous dispersion or emulsion compositions that include a polymeric binder resin and an ether amine. Specifically, the polymeric binder resin includes acid functional groups, at least a portion of which are neutralized by the ether amine such that the polymeric binder resin is dissolved or dispersed in the water, provided that the polymeric binder resin is not a polyurethane and the ether amine is a compound of formula I: wherein R 1 and R 2 are independently C 1 -C 4 alkyl or C 3 -C 4 cycloalkyl group; or R 1 and R 2 , together with the nitrogen to which they are attached, form a C 4 -C 5 membered heterocycloalkyl ring; A is a C 1 -C 6 alkylene or C 1 -C 6 cycloalkylene ring; and R 3 is C 1 -C 4 alkyl or C 3 -C 4 cycloalkyl group; provided that the compound of formula I contains no more than 10 carbons.
