Product Applications
  • D.E.H.® 87 is a phenolic hardener designed for powder coating applications.
  • It is fully compatible with epoxy resins and can be formulated into decorative or protective powder coatings.
  • However, D.E.H.® 87 was developed primarily for functional powder coating applications (FBE) requiring a high degree of flexibility and a good storage stability. D.E.H.® 87 contains no flow modifier and curing accelerator.
  • These additives must be added separately to the powder coating formulation.
  • Imidazole and some of its derivatives are examples of effective accelerators for the curing of solid epoxy resins with D.E.H.® 87.
  • 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.
  • Suitable pre-treatments such as blast cleaning are suggested.
  • This product is suitable for use in powder coatings.
