Golden Cashew Products Pvt. Ltd.

Sedarapet, Pondicherry

CNSL is a reddish brown viscous liquid extracted from a soft honeycomb structure inside the cashew nutshell and is a by-product of the Cashew industry.It is extracted from the cashew nut shell, which is a pericarp fluid of the Shell nut. CNSL is a mixture of four components: all are substituted phenols - anacardic acid (I), cardanol (II), cardol(III) and 2-methyl cardol(IV).

Anacardic Acid and Cardanol are monohydric phenols whereas Cardol and 2-methyl cardol are dihydric phenols. In the nut, CNSL occurs mainly as an anacardic acid (90%) and cardol around slightly lower than 10%. The dual phenolic/alkenyl nature of CNSL makes it a potential natural raw material for the synthesis of water-resistant resins and polymers.

ApplicationsCNSL is primarily used as raw material for CNSL Liquid Resin, PF Resin and Cashew Friction Dust(CFD) for Automobile Brake linings. It is also used for the manufacture of Paint and Varnishes, Epoxy Resins and Oil soluble Resins, Surface Active Agent, Synthetic Rubber & Wax compounding, Foundry Resins, etc.

• Low-cost Phenol
• Versatility in Polymerization as Chemical Modification
• Property advantage over phenolics in application such as impact resistance, flexibility, faster heat dissipation, etc.
• Solubility in Organic Solvents
• Improved Process ability
• Low fade characteristics for friction
• Resistance to 'Cold Wear'
• Good electrical resistance
• Better water repellence
• Improved alkali and acid resistance
• Compatibility with other polymers
• Antimicrobial property

 

The CNSL-based products not only enhance and improve the quality but also impart distinct performance of the product. They find extensive use in automotive Brake Lining and Clutch facing applications as binders / friction dust. CNSL–Formaldehyde (CF) resins improve impact properties and reduce fade considerably by dissipating heat faster than phenol. Moreover, the cost of CF resins is always lower than that of PF resins.

PropertiesCNSL undergoes all typical phenolic reactions. Its versatility in polymerization, chemicals modification and low cost find its application in the polymeric based industries. Its properties have advantages over phenolic in certain applications such as impact resistance, flexibility, faster heat dissipation, anti corrosive, anti- microbial, insecticidal and resistant to alkali and acid solutions as well as mineral and fatty oils and various organic solvents.

Cardanol also known as distilled cashew nut shell liquid is obtained in the distillation process of technical cnsl under reduced pressure. The distillation takes place at high temperature and distilled cnsl vapours are received through high vacuum. The average unsaturation of about two double bonds in the side chain of the cardanol molecules make cross linking easy and provides a satisfactory gradual drying and baking properties to paints prepared from it. Because of its peculiar structure cardanol varnishes have high electric insulation, greater resistance to water, chemicals and good flexibility.
