Epoxy Diluents & Modifiers

Cardolite’s cardanol-based epoxy resins, diluents, and modifiers offer formulators versatile solutions for improving coating and adhesive performance. Our portfolio includes reactive and non-reactive diluents that reduce viscosity while enhancing flexibility, corrosion resistance, and early water resistance. These bio-based materials support low and zero VOC formulations.

We also offer difunctional glycidyl ether resins and a polyglycidyl ether epoxy novolac designed to boost system flexibility without sacrificing mechanical properties.

Reactive Diluents

513 CNSL Epoxy Diluent Series

The Cardolite 513 family of monofunctional epoxy diluents delivers efficient viscosity reduction and consistent performance.
