EPON™ Resin 1001F


EPON™ Resin 1001F is a low molecular weight solid epoxy resin derived from a liquid epoxy resin and bisphenol-A. EPON Resin 1001F is used for its application or end-use advantages in both structural and surface-coating applications as follows:

Structural applications

Because of the excellent pre-impregnation properties, EPON Resin 1001F is used in:

  • Dry lay-up laminates
  • Dry filament winding
  • Transfer molding compounds 

Surface coatings

Amine or polyamide cured coatings based on EPON Resin 1001F provide excellent:

  • Chemical resistance
  • Durability
  • Toughness
  • Adhesion

Because of these performance properties, amine and polyamide cured coatings are especially useful in maintenance and marine applications.
