Cardolite has launched NX-9014, a cashew nutshell liquid (CNSL) derived polyol for adhesive and coating applications that require protection and aesthetics in one product. The polyol provides low viscosity, good weatherability, and excellent bonding properties for high performing adhesives and coatings.
Adhesive with High Tensile Strength and Hardness
Adhesives based on NX-9014 deliver high tensile strength and hardness and maintains good elongation. Coatings based on NX-9014 are suitable for topcoats due to their low color and good resistance to UV exposure (non-yellowing). The systems show excellent bond strength to metals including challenging substrates like aluminum. All these combined properties make NX-9014 very versatile and allow this polyol to be used across multiple applications.
NX-9014 joins other high-performance polyols in Cardolite’s product offering. Depending on the application, Cardolite can offer specific solutions that include very high mechanical strength, high levels of hydrophobicity, and excellent chemical resistance amongst others.
CNSL Derived Water-resistant Polyol
Most of Cardolite polyols and diols derive from renewable, cashew nutshell liquid (CNSL). CNSL derivatives present unique qualities compared to widely known polyester and polyether polyols, and other natural oil-based polyols. The products are hydrophobic in nature and therefore provide excellent water resistance and less moisture sensitivity during cure with isocyanate. That results in increased durability and performance of the final polyurethane system. In addition, CNSL polyols and diols show fast cure with isocyanates minimizing the amount of catalysts required and allowing for quick return-to-service.
Different from other renewable polyols obtained from soy and castor oil, CNSL polyols have an aromatic structure that translates into excellent thermal resistance and chemical resistance to acid and alkaline solutions. Moreover, the combination of aromaticity and long aliphatic chain delivers hydrolytic stability and mechanical strength to CNSL based systems.
