Abstract
An epoxy resin composition containing a) an epoxy resin and b) a liquid amine terminated polyamine curing agent prepared by condensing an aminoalkylpiperazine and a dicarboxylic acid. The epoxy resin composition typically requires less than 35% of solvent to produce a sprayable viscosity. A hydroxy-functional flexibilized resin is also produced by reacting (a) an epoxy resin, (b) a liquid aminoalkylpiperazine-based amine terminated polyamine and (c) a hydroxy-functional amine.
