Waterborne Solutions for Zero and Low V.O.C. Epoxy Systems

Cardolite’s waterborne curing agents enable high performing epoxy coatings and adhesives with performance similar to solvent-borne counterparts.

High Biocontent Polyurethane Polyols

Cardolite’s CNSL polyols and diols designed for adhesives, coatings and foams, provide excellent water resistance, hydrolytic stability, reactivity and flexibility with the additional benefit of being renewable and non-toxic.

Safer Replacements for Nonyl Phenol

Cardolite’s cardanol grades are excellent non-toxic alternatives to nonyl phenol as accelerators for epoxy-amine reactions, diluents for epoxy systems and building blocks for polymers.



Cardolite phenalkamines are made through the Mannich reaction of cardanol, formaldehyde, and certain amines. They provide very fast cure even below zero temperatures, and excellent adhesion and corrosion protection even on immersed surfaces. Cardolite phenalkamides deliver fast cure and corrosion protection, but with longer pot life, better flexibility and UV resistance, and extended overcoat window. The NX-8000 Series waterborne line of curing agents enables zero and low V.O.C. epoxy coatings with solvent-like performance. Cardolite’s comprehensive polyamide offering includes standard, well-proven grades and some specialty formulations.


Cardolite offers a unique line of cardanol-based epoxy resins, diluents, and modifiers that provide formulators with valuable tools to meet certain target properties. Cardolite resin and modifier portfolio is comprised of reactive and non-reactive epoxy diluents and multi-purpose modifiers that not only lower viscosity, but also improve anti-corrosion properties, flexibility, and early water resistance. These cardanol-based diluents allow formulators to achieve enhanced product performance and workability in high solids coatings. In addition, a difunctional glycidyl ether resin and a polyglycidyl ether epoxy novolac are offered to formulators that need to increase flexibility of the system without compromising other properties.


Cardolite offers a line of renewable, cashew nutshell liquid (CNSL) based polyols that have unique qualities compared to widely known polyester and polyether polyols, and other natural oil based polyols. CNSL polyols are very hydrophobic because of the long aliphatic chain of cardanol, and fewer ether oxygen atoms compared to typical polyether polyols (less hydrophilic). This hydrophobicity provides excellent water resistance and less moisture sensitivity during cure with isocyanate for increased durability of the final polyurethane system. CNSL diols combine the benefits of CNSL and Polyester technologies resulting in excellent solvent, alkaline, acid, and water resistance, good dimensional stability, and balanced physical properties.


Blocked isocyanate technology allows 1K polyurethane and 1K/2K epoxy systems to achieve safer processes and higher performance coatings and adhesives. Key improvements include reduced free isocyanates and extended storage stability, specially for one component formulations, by minimizing moisture sensitivity through capping the isocyanate. 

Due to raised health concerns over phenols and Nonyl phenol (NP), industries have requested for non-toxic alternatives with similar performances and benefits.  NX-2026, a renewable, very high purity derivative from cashew nutshell liquid, has been introduced as non-toxic blocking agent alternative with favorable deblocking conditions, low viscosity and excellent stability at room temperature.  Moreover, NX-2026 blocked prepolymer systems provide improved elongation, bond strength and T-peel to epoxy systems cured with phenalkamines without compromising cure speed along with moisture resistance.


Cardolite offers a variety of cardanol grades that can be used as building blocks in high performance specialty chemicals. Cardanol is a versatile molecule that can be functionalized in many different ways on the phenolic OH, aromatic ring and double bonds of the long aliphatic side chain. 

CNSL can be processed to yield different cardanol grades with a wide range of color, odor, and purity among other parameters. Recently, Cardolite developed a proprietary process technology that enables very high purity cardanol grades with ultra light color (Gardner of 1 or less) and good stability over shelf life. This leap forward in CNSL processing technology is expanding the use of cardanol as an intermediate and as an epoxy diluent and modifier. Cardanol is a suitable replacement for potentially toxic phenol diluents such as nonyl-phenol as it provides lower viscosity, better flexibility, and similar acceleration effects to epoxy-amine reactions.


Cardolite is a leading producer of high performance cashew based friction materials used in the OEM and aftermarket automotive (car, bus, truck, motorcycle) and rail brake industries.

Cardolite offers a wide range of brown and black friction particles and cashew nutshell liquid binder resins that are designed to address the different needs of semi-metallic, ceramic, asbestos and non-asbestos formulations for normal and heavy duty brake pads, drum linings, and train blocks. Overall, these products reduce wear, improve friction stability, act as noise dampeners, and can be formulated to give high heat resistance, and excellent hardness and flexibility.


FormuLITE amine-cured epoxy systems are specially designed for composite manufacturers that want a ready-to-use, high performance bio-based resin matrix. In the FormuLITE composite epoxy line, both the resin and the amine hardener are made from high amounts of renewable resources that include cashew nutshell liquid.

FormuLITE epoxy systems offer low viscosity, good wetting of the reinforcements (glass, carbon and natural fibers), extended pot-life and well-balanced mechanical properties. In addition, the use of CNSL as a key building block yields excellent properties such as high thermal resistance and good protection against water uptake, acid and alkali solutions. Manufacturers of medium to large size composite parts by wet lay-up, resin transfer molding (RTM), lamination and vacuum infusion can benefit from the performance delivered by FormuLITE epoxy-hardener combinations. Moreover, the ease of use of FormuLITE systems make them a good choice for do-it-yourselfers that long for factory-like results.
