EPIKOTE™ Resin 816


EPIKOTE Resin 816 is a low viscosity epoxy resin produced from bisphenol A and epichlorohydrin, and containing an added proportion of Cardura E10P (glycidyl ester of neodecanoic acid) as a reactive diluent. EPIKOTE 816 is of low volatility and mild odour, which gives the resin its agreeable handling characteristics. EPIKOTE 816 provides good pigment wetting and good resistance to filler settling. As judged by laboratory tests, EPIKOTE 816 is considered to have a moderate resistance to crystallisation on storage.


  • Low viscosity
  • Low volatility
  • Good resistance for crystallization
  • Excellent pigment/filler and substrate wetting
  • Imparts good mechanical  performance
