EPON™ Resin 58901


EPON™ Resin 58901 is an elastomer modified epoxy functional adduct formed from the reaction of EPON Resin 828 and a carboxylated butadiene-acrylonitrile elastomer. Elastomer content is approximately 5% by weight. The primary use of EPON 58901 is in the modification of conventional epoxy systems to increase flexibility and impart tack to provide early green strength to adhesive systems.


  • Broad compatibility with conventional bisphenol A epoxies
  • High viscosity
  • Imparts tack and early green strength into adhesive systems
