EPON™ Resin 869

Description

EPON™ Resin 869 is a low viscosity epoxy resin produced from the reaction of bisphenol F and epichlorohydrin, containing no diluent. Like other bisphenol F epoxy resins, it has improved chemical resistance and lower viscosity than bisphenol A epoxy resins. The higher molecular weight of EPON Resin 869 provides some improvement in crystallization resistance versus other bisphenol F epoxy resins, such as EPON Resin 862. The low viscosity compared to bisphenol A epoxy resins provides good fiber or pigment wetting, and allows the use of less reactive diluents in formulations to achieve similar system viscosities and superior mechanical properties.

Benefits

  • Lower viscosity without diluent
  • Good hardness development and mechanical properties, especially versus diluted resins
  • Improved resistance against crystallization, which can be enhanced further when blended with EPON Resin 828
  • Imparts good chemical resistance
  • Good pigment wetting
  • Good resistance to pigment settling
