Abstract
Epoxy resin composition curing agents, which include a primary amino alcohol, are disclosed. Specifically, the invention relates to curing agents which include a primary amino alcohol physically blended therewith. Alternatively, the invention relates to curing agents which include a primary amino alcohol reacted into a resinous phenolic compound. Resin systems utilizing the curing agents of the invention exhibit enhanced hot wet adhesion to metal substrates and are particularly useful in the manufacture of powder coatings for pipe.
