Cashew Nut Shell Liquid

C.N.S.L 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. It 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.
