D.E.R.® 668-20

D.E.R.® 668-20 Solid Epoxy Resin is a high molecular weight solid reaction product of epichlorohydrin and bisphenol A. D.E.R.® 668-20 Solid Epoxy Resin is designed primarily for use in one pack stoving enamels in combination with heat-reactive cross-linking agents such as amino- and phenol- formaldehyde resins. D.E.R.® 668-20 Solid Epoxy Resin may also be used as binder in ambient curing systems in combination with isocyanate cross-linkers. Finishes made from D.E.R.® 668-20 Resin are suitable for metal decoration, interior and exterior can coatings, tube and drum linings, coil primers and many other industrial applications.
