Cardolite® NX-9203 is a polyester diol based on cashew nutshell liquid technology. NX-9203 provides improved water resistance, reduced moisture sensitivity and it is suitable for 2K Polyurethane coatings and adhesives and sealants. It also has excellent compatibility with various diols and polyols, i.e. polyether diols and polybutadiene diols (PolyBD).
Cardolite® NX-9203LP is a lower reactivity version of NX-9203, suitable for prepolymer making

Features and Benefits:
Cardolite CNSL-based polyols 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, the absence of ester bonds (hydrolyzable), 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. In addition, CNSL polyols show a fast cure with isocyanates minimizing the number of catalysts required and allowing for quick return-to-service.
