EPIKOTE™ Resin 256


EPIKOTE Resin 256 is a liquid epoxy resin based on a bisphenol A resin (produced from bisphenol A and epichlorohydrin), a bisphenol F resin (produced from bisphenol F and epichlorohydrin) and an added proportion of a mono-epoxidised alcohol as reactive diluent, which has been modified to make it readily dispersible in water. As judged by laboratory tests, EPIKOTE 256 is considered to have excellent resistance to crystallization on storage.


  •  Low viscosity
  •  Easy emulsifiable with water
  • Can be combined with a water emulsifiable curing agent.
  • Good pigment/filler and substrate wetting
  • Superior hydrolysis stability of the emulsion
