The CTech-LLC® epoxy vinyl ester resin (NVER™990) is a novolac-epoxy based resin, designed to provide chemical resistance in combination with temperature performance. It offers a high resistance to strong acids, oxidizing environments and organic solvents at elevated temperatures.

Key Features

  • Excellent corrosion resistance
  • Excellent impact strength
  • High tensile elongation
  • High Heat Resistance
  • Low Viscosity
  • Superior corrosion resistance to a wide range of acids, bases, chlorides, solvents, and oxidize
  • Epoxy novolac vinyl ester resin.
  • NVER™990 resin provides resistance to acids and has superior resistance to many organic solvents.
  • NVER™990 resin has high thermal resistance and good mechanical properties.
  • FRP equipment produced using NVER™990 Epoxy novolac vinyl ester resin retains strength and toughness at elevated temperatures.
  • NVER™990 Epoxy novolac vinyl ester resin is successfully used in heavy duty industrial applications over many years


The NVER™990 resin is suitable for use in hand lay-up, spray-up, and filament winding processes where a high resistance to solvents and chemicals and good retention of strength and toughness at elevated temperatures are required.
