CURABLE ALKANOLAMINE-CONTAINING EPOXY POWDER COATING COMPOSITION

摘要

The present invention provides a curable alkanolamine containing epoxy powder coating composition comprising at least one epoxy resin, at least one alkanolamine, a curing agent in an amount effective to cure the coating and optionally at least one zinc borate compound. Further, the present invention provides a method of cathode corrosion protection which includes the steps of subjecting a metal substrate to a mechanical treatment, applying the curable alkanolamine containing epoxy powder coating composition to the surface of the metal substrate, and polarizing the coated material as a cathode. The present invention also relates to a process for making and applying the alkanolamine containing epoxy powder coating compositions of the present invention.
