Cardolite® NX-9201 is a di-functional CNSL polyester diol with reduced reactivity. It offers excellent moisture resistance and hydrolytic stability in aqueous solutions. Compatibility with polyether diols and Poly BD are outstanding, thus, when Cardolite® NX-9201 is blended with other diols, it shows significant improvement of hydrolytic stability. Cardolite® NX-9201 is more suitable for prepolymer synthesis and can be used in 1K/2K polyurethane adhesives and sealants, coatings, elastomers and flexible foams.
Cardolite® NX-9201LP is a lower reactivity version of NX-9201, suitable for prepolymer making.

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.
