CNSL Oil About

Cashew Nut Shell Liquid commonly known as CNSL oil, is a dark brown viscous liquid extracted from the shell of cashew nuts. It is a renewable and bio-based industrial raw material widely used in chemical, polymer, coating, resin, friction, and adhesive industries. CNSL contains phenolic compounds such as anacardic acid, cardanol, and cardol, which provide excellent chemical resistance, thermal stability, and binding properties.
