Cardolite introduces CNSL Polyol Technology at ECS

摘要

Cardolite is introducing a comprehensive line of cashew nutshell liquid (CNSL) based polyols for adhesives and coatings at the European Coatings Show in Nurnberg. Polyols derived from CNSL have unique qualities compared to widely known polyester and polyether polyols, and other natural based polyols. Hydrophobicity is one key advantage provided by the long aliphatic side chain present in CNSL. This hydrophobicity reduces moisture sensitivity during cure with isocyanate and results in outstanding water resistance for increased durability of the final polyurethane product. Different from other renewable polyols obtained from soy and castor oil, CNSL based polyols have an aromatic structure that translates into excellent chemical and thermal resistance. Moreover, the combination of aromaticity and long aliphatic chain delivers hydrolytic stability and high tensile, compression, and flexural strength to CNSL based polyols. This new product line is comprised of diols, and medium and high functionality polyols. CNSL diols can be formulated into coatings, adhesives and sealants or be used as a building block to produce polyurethane pre-polymers.
