EPON™ Resin 58034


EPON™ Resin 58034 is an elastomer modified epoxy functional adduct formed from the reaction of HELOXY™ 68 Modifier and a carboxyl terminated butadiene-acrylonitrile elastomer. Elastomer content is approximately 50 percent by weight. The primary use of EPON 58034 is in the modification of conventional epoxy systems to increase flexibility, adhesion properties and fatigue resistance.


  • High elastomer content provides compounding flexibility to incorporate desired levels of elastomer into finished formulation
  • Compatible with conventional bisphenol A epoxies
  • Low viscosity
  • Imparts improved peel strength and fatigue resistance into adhesive systems
