D.E.H 80 Phenolic Dow Chemical Crosslinking / Coupling / Curing Agents Epoxy Resins Coatings >> Powder Coatings Powder coating >> Architectural / Decorative Powder coating >> General industrial D.E.H.* 80 epoxy curing agent is a phenolic hardner and a reaction product of liquid epoxy resin and bisphenol- A containing a curing accelerator and a polyacrylate flow modifier. D.E.H. 80 epoxy curing agent is designed for powder coating applications. It is fully compatible with epoxy resins and it can be formulated into high gloss and good flow decorative powder coatings or into protective coatings. When formulated into white or pastel shades, formulations based on D.E.H. 80 curing agent may exhibit a tendency towards yellowing when subjected to high baking temperatures or to over-bake. The moderate reactivity of D.E.H. 80 curing agent can be increased by using either D.E.H. 81 or D.E.H. 82 hardeners as part of the formulation. The performance of phenolic cured epoxy powder coating formulations and particularly their adhesion to metal substrates will be greatly affected by the quality of the surface preparation, and suitable pretreatments such as phosphates or blast cleaning are suggested as a minimum requirement. This product is suitable for use in powder coating applications. Phenolic hardner and a reaction product of liquid epoxy resin and bisphenol- A containing a curing accelerator and a polyacrylate flow modifier. Used for powder coating applications. Offers compatibility with epoxy resins. Suits for high gloss and good flow decorative powder coatings and protective coatings.
