Cardonal(Upcoming)
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.
Description
Cardanol also known as Cashew Phenol 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.
