D.E.R.™ 661-A80 Epoxy Resin Solution
D.E.R. 661-A80 Epoxy Resin Solution is a low molecular weight reaction product of liquid epoxy resin and bisphenol A dissolved in acetone.
D.E.R. 661-A80 Epoxy Resin Solution is a low molecular weight epoxy resin solution developed for use in high solids / high build coating formulations. This epoxy resin solution can provide the high solids and chemical resistance of liquid epoxy resins together with the adhesion, flexibility and fast cure of higher molecular weight resins.
D.E.R. 661-A80 Epoxy Resin Solution can form the basis of a two component coating system with either polyamine, polyamide or polyamidoamine curing agents, providing high quality coatings which are resistant to a number of chemical reagents. These coatings also exhibit the excellent mechanical properties normally associated with a 1-type solid epoxy resin, which finds usage in a variety of applications.
This product is suitable for use in marine and protective coatings.
