 CNSL has innumerable applications, such as friction linings, paints, laminating resins, rubber compounding resins, cashew cements, polyurethane based polymers, surfactants, epoxy resins, foundry chemicals, and intermediates for chemical industry.  CNSL offers much scope and varied opportunities for the development of other tailor-made polymers.

 Cashew Nut Shell Liquid undergoes all the conventional reactions of phenols, CNSL aldehyde condensation products and CNSL based phenolic resins are used in applications such as surface coatings, adhesives.  Various polyamines synthesised from CNSL are used s curing agents for epoxy resins.  CNSL and its derivatives have been used as antioxidants, plasticizers and processing aids for rubber compounds, modifiers for plastic materials and used to provide oxidative resistance sulphur-cured natural rubber products.  It is also added to rubber gum stock or nit rile  rubber to improve the processability, mechanical properties and resistance to crack and cut properties of the vulcanisates.




A Number of products based on CNSL are used as antioxidants, stabilisers and demulsifies for petroleum products.  Soluble metal derivatives of Cashew Nut Shell Liquid are used to improve the resistance to oxidation and sludge formation of lubricating oils.  

CNSL and its derivatives are also used as demulsifying agents for water in oil type petroleum  emulsions.

CNSL used for manufacturing of C.N.S.L based Resins, Cardanol (card-phenol) Anti corrosive hiring chemicals, Acid resistant paints & varnishes, Insecticides and Fungicides, cashew lacquers bakelite and enamels electrical conductress cashew cements foundry chemicals.CNSL-2
