Defunctionalized epoxy resins useful in coatings

摘要

Amine defunctionalized epoxy resin for coating compositions particularly suitable for application onto metal surfaces such as can stock was found to have improved blush and stain resistance when employing reaction ratios near 1:1 equivalent of epoxy group to equivalent of primary amine or ammonia. A method is also disclosed for carrying out the defunctionalizing reaction while avoiding gelation.
