Cashew Nut Shell Liquid (CNSL)

Eco-friendly, high-performance raw material for coatings, resins, and friction products.

What is Cashew Nut Shell Liquid (CNSL)?

CNSL is a dark brown, viscous liquid obtained as a byproduct during the processing of cashew nuts. It contains approximately 70–80% anacardic acid, along with cardol, cardanol, and trace methyl cardol, making it chemically active and suitable for modification into various resins and industrial intermediates.

 

Unlike petroleum-based chemicals, CNSL is renewable, non-toxic, and biodegradable, offering industries an eco-friendly alternative.

CNSL serves as a valuable raw material in many industrial formulations:

Coatings and Painting

  • CNSL-based resins for corrosion-resistant coatings and marine paints
Used car clutch, macro shots for friction linings, isolated on a white background.

Friction Materials

  • Brake pads/clutch linings,improves wear resistance, noise control, and heat tolerance

mixer's paddles are covered in epoxy resin and have been placed on the lid of the bucket

Epoxy Curing Agents

  • CNSL derivatives are used in emulsifiers, detergents, and pesticides

Adhesives and Sealants

  • Phenolic CNSL resins improve bond strength and flexibility
Rubber conveyor belts

Rubber Compounding

  • Used as a plasticizer, modifier, or curing agent in rubber formulations
