Abstract
Abstract The invention is an epoxy resin coating composition. The composition comprises: 1. a bisphenol A resin, and 2. an acrylate ester, reacted with a mixture of 3. a polyether polyamine of the formula: a. NH2CH(CH3)CH2[OCH2CH(CH3)]xNH2 wherein x ranges from 2 to 6, or b. <IMAGE> wherein x+y+z ranges from 4 to 6; and 4. piperazine. The weather resistant formulations cure rapidly to form attractive blemish-free, blush-free coatings.
