As a diluent, it provides good hardness development at ambient and low temperatures. LITE 513DF is low in viscosity and provides excellent dilution power as indicated by the addition by weight curve with bisphenol A type liquid epoxy resin. This material is suitable for epoxy systems such as coatings, one- and two- component adhesives and composites. LITE 513DF is a new CNSL-based, high bio-content diluent with lower epoxy equivalent weight than standard 513. Both products show very good UV resistance with excellent gloss retention for use in lighter color coatings. Their high hydrophobicity results in excellent water resistance, and more importantly, excellent corrosion protection on immersed and vapor exposed surfaces. These products show good hardness development while providing improved flexibility and impact resistance. 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. The graph on this page shows a comparison of dry hard times and gel times between benzyl alcohol, UL 2020, and NX-2026 as reference.Ĭardolite LITE 2100(R) are low color and low viscosity CNSL modified hydrocarbon resins. Ultra LITE color cardanol grade, NX-2026, and Ultra LITE 2020 (UL 2020) can be excellent renewable and lower volatile alternatives to Benzyl Alcohol with appropriate adjustments in formulations to account for viscosity and cure properties differences. Hence, they are suitable as nonyl phenol replacements. Furthermore, cardanol grades act as accelerators between epoxy resins and amines. The NX-202X line represents various cardanol grades suitable for use as diluents in various systems that include epoxy and polyurethane chemistries. The Ultra LITE 2020 family is made of multi-purpose diluents that can also help lengthen gel time. Those combined properties help ensure our diluents have a positive effect on systems overall performance. Moreover, cardanol’s aromatic ring improves chemical resistance of those derivatives. Additionally, these diluents provide increased flexibility and impact resistance due to the long aliphatic chain in their backbone. All cardanol derived grades carry the benefits of high hydrophobicity and therefore, excellent water resistance.

Industrial and Transportation AdhesivesĬardolite’s line of cardanol-based non-reactive epoxy diluents are an effective way to reduce viscosity without the use of solvents.
