EPON™ Resin 1001-O-75


EPON™ Resin 1001-O-75 is a solid resin solution of EPON Resin 1001F cut to 75% weight in Methyl n-Amyl Ketone(Mn-AK). The EPON Resin 1001F is derived from bisphenol A and epichlorohydrin. This epoxy resin solution finds application in solventborne amine or polyamide cured coatings.

The 1990 Clean Air Act Amendments require significant reductions in the emissions of certain EPA-defined hazardous air pollutants (HAP). A number of the targeted substances are solvents commonly used in ambient cured coatings. EPON Resin 1001-O-75 offers the coatings formulator a resin solution with high solids and good solubility, using a non-HAP solvent.


  • Contains a non-HAP solvent (Methyl n-Amyl Ketone).
  • Mn-AK is a slower-evaporating solvent (comparable to propylene glycol monomethyl ether acetate) that is adaptable to most air-dry or baking systems.
  • Easy handling solution that is readily thinned or reduced with other organic solvents.
  • Crystal clear solution requiring no additional filtration.
