Diluents & Modifiers Portfolio

Cardanol-based epoxy resins, diluents, and modifiers offer formulators versatile formulation tools to enhance coating and adhesive performance. Reactive and non-reactive diluents reduce viscosity for low and zero VOC formulations while improving flexibility, corrosion resistance, and water resistance. Difunctional epoxy resins and polyfunctional epoxy novolacs further enhance system flexibility and toughness without greatly compromising mechanical properties.

Reactive Diluents

Cardolite Ultra LITE 513 molecule

Monofunctional Epoxy Diluent Series

The Cardolite family of monofunctional epoxy diluents deliver efficient viscosity reduction and consistent performance. NC-513 is the standard grade, while Ultra LITE 513 offers higher purity, lower viscosity, and very light color, making it an excellent choice over traditional monofunctional glycidyl ether diluents.

Key Benefits:

  • High dilution efficiency
  • High flexibility
  • High water and chemical resistance
  • Good toughness and thermal shock resistance
  • Good epoxy resin and curing agent compatibility
  • Alternative to other monofunctional glycidyl ethers
  • 100% bio-based material
