HIGH PERFORMANCE CHEMICAL 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. Moreover, the long aliphatic side chain of cardanol provides excellent hydrophobicity for these CNSL resin modifiers derivatives.
Cardolite also offers non-CNSL monoglycidyl ethers as an option for formulations that can’t be changed to CNSL-based materials. Please see below for a complete list of epoxy resin modifiers and diluents.
MONO-FUNCTIONAL EPOXY DILUENTS
Cardolite NC-513, LITE 513E and Ultra LITE 513 are monofunctional reactive epoxy diluents that can be used to increase the flexibility and impact, and chemical and water resistance of epoxy coatings. They are both identical in chemical make-up and excellent alternatives to traditional glycidyl ethers.
Cardolite NC-514 and NC-514S are flexible difunctional glycidyl ether epoxy resins. The chain of 8 carbons separating the aromatic groups allows this resin to be used in conjunction with traditional epoxy resins to increase coating flexibility, abrasion resistance, and water and chemical resistance without adversely affecting other properties.
Cardolite NC-547 is a polyglycidyl ether epoxy novolac resin derived from cardanol. This resin can be used in conjunction with standard epoxy resins to bring additional flexibility and longer pot life to coatings without adversely affecting chemical and water resistance.
MULTI-FUNTIONAL EPOXY MODIFIERS
Cardolite UL/LITE 2020 and NX-202X lines are low viscosity multi-purpose resin diluents and modifiers. The long hydrophobic aliphatic side chain of the cardanol gives these products a very low viscosity and provides excellent early water resistance and corrosion protection. Ultra LITE 2023, NX-2023(D), and NX-2026 are the wet color stable versions of the NX-202x product family. Ultra LITE 2020 is the lighter color version of LITE 2020.
Cardolite LITE 2100(R) are low color and low viscosity CNSL modified hydrocarbon resins. They are designed to enable high solids and solvent free formulations by lowering the viscosity of epoxy resins more efficiently than typical phenol based hydrocarbon resins and by improving overall system compatibility for better film formation. These products show good hardness development while providing improved flexibility and impact resistance. Their high hydrophobicity results in excellent water resistance, and more importantly, excellent corrosion protection on immersed and vapor exposed surfaces. Both products show very good UV resistance with excellent gloss retention for use in lighter color coatings.
