Cashew Nutshell Liquid (CNSL) products have shown superior hydrolytic stability and water resistance at various conditions including high temperature, high humidity, acidic, and alkaline conditions.
In the case of epoxy technology, the incorporation of CNSL epoxy resins and curing agents has demonstrated not only increased water protection but also fast cure and high strengths.
Hydroxyl functional CNSL products, i.e., polyols, diols, have offered reduced moisture sensitivity and excellent hydrolytic stability for polyurethane adhesives and sealants.
