Applications of Cardanol

Oil Soluble Resins

The meta substitution and the long hidrocarbon chain in its molecule makes the resins prepared with Cardinol, highly soluble in oils and imparts superior properties such as high electric insulation and resistance against chemicals to its films. It is to manufacture both solid and semi solid resol or novolac type of resins depending upon the nature of catalyst and the aldehyde compound.

Cardanol resin varnishes have good electrical insulating properties and resistance against water and chemicals. They give superior quality Stamping Varnishes. Because of their high insulation and dielectric losses, these varnishes are preffered to compositions based on usual Phenol such as Cresol or Substituted phenols.

Surface Coatings and Paints

Cardanol resin Varnishs in addition to water and Chemical resistance have good air drying and baking properties. These compositions are suitable for wood finishes, food can lacquers taxtile bobins and high quality paints. Stoving paints can be prepared which could be baked at 60°C. The Cardanol based resins have good compatibility with other synthetic resins such as alkydes, epoxies chlorinated rubber, Phenolic etc., and can serve as raw material for variety of paints.

Lamination Industry

By partly replacing the Phenol or Cresol in alcohol soluble resins used for Lamination one could prepare resins which imparts greater flexibility resistance to Chemical and water, and superior electrical insulation to the lamination sheets

Surface Active Agent

Sulphonated ether of Cardanol has been found to be wetting agent and finds use in Textile Industry, ethoxylated Tetrahydrocardanol Sulphonate performs better at high temperature than the detergents based on Dodoeyl benzene.

Pesticides

Chlorinated Cardanol is reported to have good insecticidal, pesticidal and germicidal properties. Cardanol Formaldehyde resin is also used as a solvent for well known pesticides such as Pyrethrin and Rotanes. Paranitro Tetrahydro Cardanol finds use as a coupling compound in sprayable pesticides such as Parathion.

Rubber Compoundings

Oil soluble Cardanol resins are used in Rubber Compounding. They impart high tear strenght and resistance against Petroleum based solvents. Pure Cardanol acts as a Deoxident and Plasticizer when incorporated in rubber. Its ethers are also used as plasticizers for synthetic rubbe to reduce the shore hardness and improve the ageing properties.

Azo dyes

3 pentadecyl phenol and sulphonated products of Cardanol are being used as intermediates for Azo Dyes.

Wax Substitutes

Waxing solids with high melting points could be prepared from Cardanol resins and suitable Amide such as Stearamide. When 3 pentadecyl phenol is reacted with 1:4 Dichlorobutane a wax with a melting point of 90/93°C is obtained. These waxes are comparatively cheaper and compatible ith other waxes such as bees wax, carnauba wax, paraffin wax etc. etc.

Mineral Oil Additives

Mineral oil additives based on Amino Cardanol ethers of hydronated Cardanol and salts of its Sulphonated ethers are found to improve the viscosity index of mineral oil, inhibit sludge formation and antioxident properties.

Food Can lacquers

Co-polymers of Cardanol with other film forming materials give good quality lacquers giving golden yellow films both of air drying and baking type. These have been found to be very effective for food can application.

Adhesives based on Cardanol Resins give superior water resistance and bonding properties to the plywood.

Adhesives

Many types of adhesives and cements can be prepared with Cardanol. When it is reacted with Epichlorohydrin and modified with Phthalic Anhydride a coating compound is obtained which has excellent film properties and adhesion.

An excellent quality of Friction dust could be prepared from Cardanol which finds use brakelinings and Clutch facings.
