Cashew Nutshell liquid (CNSL), a by-product from cashew industrial processing and one of the richest natural sources of phenolic compounds, emerges as a promising and renewable feedstock for the development of a wide range of functional products.Cashew nut shell liquid (CNSL) is a renewable natural resource obtained from the Cashew Nut Shell. It is a natural and renewable biomaterial. CNSL is composed of four major phenolic liquids, namely: anacardic acid, cardanol, cardol and traces of 2-methylcardol in varying ratios. CNSL is primarily used as raw material for Making Cardanol ,Paints and Varnishes, Friction Linings,Surfactants, CNSL Liquid Resin, Laminating Resins, Cashew Cements, Polyurethane Based Polymers, PF Resin and Cashew Friction Dust (CFD) for Automobile Brake linings, Epoxy Resins and Oil soluble Resins, Synthetic Rubber & Wax compounding,Foundry Chemicals, Low-cost Phenol
CNSL End User Industry- Making Cardanol ,Coating Industry, Automotive Industry,Fuel Industry,Leather Industry,Tobacco Curing Industry. CNSL is a potential substitute for petroleum-based raw materials . Furthermore, the potential use of CNSL as a biofuel or additive to biofuel has been demonstrated.
CNSL being used as energy input in the energy sector too. CNSL has qualities replicating furnace oil. The potential as fuel gives it additional value. As a bio-fuel, it can compete with costlier petroleum products.
CNSL is mainly used as fuel for furnaces in factories smelting aluminum, steel, silicates, chromite bricks, etc. by mixing fuel oil or completely replacing fuel oil to reduce costs.
Green Nanotechnology :Exploration of sustainable alternatives to chemicals derived from petro-based industries is the current challenge for maintaining the balance between the needs of a changing world while preserving nature. The major source for sustainable chemicals is either the natural existing plant sources or waste generated from agro-based industries. The utility of such resources will supplement new processed materials with different sets of properties and environmental friendliness due to their biodegradability and low toxicity during preparation, usage and disposal. Cashew nut shell liquid (CNSL) is a renewable natural resource obtained from the Cashew Nut Shell. It is a natural and renewable biomaterial. At Sri Devi Group , we are taking action to protect our planet as individual and business by promoting the use of sustainable and bio-based product like Cashew Nut Shell Liquid-CNSL .

(Natural)
Natural CNSL is a extracted liquid from Cashew Nut Shell. It contains approximately 70% of anacardic acid, 18% of cardol, 5% of cardanol and 2% of 2-methyl cardanol with the remainder being made up of other phenols and less polar substances. Anacardic acid and Cardanol are monohydroxy phenols. Cardol and methyl cardanol are dihydroxy phenols.
(Technical/Treated)
CNSL (Treated), the heating process of the Natural CNSL leads to decarboxylation of the anacardic acid to Cardanol and the typicall composition of technical CNSL is approximately 52% cardanol,10% cardol, 30% polymeric material, with the remainder being made up of other substances.

CNSL Applications:
Industrial Coating, Enamel/Paints, Marine Paints, Acid resistant Paints, Varnishes -CNSL based surface coatings possess excellent gloss and surface finish with optimum levels of toughness and elasticity. It is widely known that CNSL resin is added to synthetics by paint/varnish manufacturers to control properties and to reduce cost. Its anti-microbial, acid resistant and rust proof properties are well known and have been utilized in protecting a bottom of the boat hulls. Because of its dark colour, its outlets are restricted to anti corrosion primers, black enamels, marine paints. CNSL is an excellent raw material for the number of anti-corrosive paint formulations CNSL modified by heating in the presence of certain accelerators give stoving enamels resistant to alkali and acid solutions, mineral and fatty oils and various organic solvents. Coating compositions possessing insecticidal properties are obtained by adding DDT, gammaxene, etc. to CNSL or chlorinated CNSL, after treatment with formaldehyde, gums and resins and drying or semi-drying oils.
CNSL as surfactant: Surfactants are amphiphilic molecules constituted of a hydrophobic tail and a hydrophilic head. They are basically used as detergents, wetting and/or foaming agents, emulsifiers or dispersants, and demulsifies due to their ability to lower the surface tension of a liquid, between two liquids, or between a liquid and a solid
Binders -CNSL is also used as a substitute for linseed oil in the manufacture of foundry core oil, which is used as a binder in the foundry.
Rubber -Used as a processing aid, which enhances the vulcanization properties. CNSL enhances the insolubility of natural rubber vulcanizates in petroleum solvents.CNSL used to provide oxidative resistance to sulfur-cured natural rubber products.Sulfurated CNSL is added to rubber gum stock or nitrile rubber to improve the processability, mechanical properties and resistance to crack and cut.
Adhesive -Adhesives suitable for plywood are made by oxidizing CNSL with potassium permanganate or manganese dioxide at 100degC reacted with para-formaldehyde and compounded with CuCl2. Also CNSL modified with furfural, aniline, xylol, etc. gives good plywood adhesives
CNSL Based Resins -It is highly suitable for surface coating application, where outstanding film properties and very high resistance to water and chemicals are required. Therefore, CNSL Resin is used commonly as a paint raw material due to its high water and chemical resistant property.
CNSL Formaldehyde Resins (Novolac) -These resins can be used for Surface Coatings with or without oil modification when high chemical resistance is desired.
CNSL Aldehyde Resin -Excellent material for the purposes like Insulating Varnishes, Molding Powders, Brake Lining Compositions, etc.
Resole type CNSL formaldehyde resin -Resole type CNSL formaldehyde resin is used as adhesive in the preparation of composite wood, medium density particle board etc.
Foundry Resins – Proven material in the formation of foundry cores.
Rubber compounding Resins : Incorporation of CNSL products in rubber improves tensile strength and abrasion resistance, reduces fatigue, enhance self adhesion, rubber to cord adhesion ,contributes to antioxidant and antiozonant activity . The fast curing cashew modified phenol-formaldehyde resins enhance the resistance of the product to aging, chemical attack and the action of solvents and acids .
