Cardanol is a natural phenol obtained from anacardic acid, the main component of cashew nutshell liquid (CNSL), a byproduct of cashew nut processing being an eco-friendly substitute for phenols.
Cardanol contributes to improved flexibility, good drying after baking, high electric insulation properties and thermal stability.These properties make Cardanol an effective substitute for the petroleum-based Phenol.
Cardanol finds use in the chemical industry in Oil and Alcohol soluble resins, laminating resins, rubber compounding and coatings, serving as an excellent raw material for the preparation of high grade insulating varnishes, paints, enamels. It is used in friction materials, and surfactants as pigment dispersants for water-based inks and to make phenalkamines, which are used as curing agents for the durable epoxy coatings used on concrete floors. Cardanol can substitute Phenol in up to 30% in phenolic resins used as plywood bonding resin and for the lamination industries.
