Cardanol’s basic ingredient is cashew nut shell liquid, which contains anacardic acid, a minor amount of Cardol, and methyl variations. Cardanol has achieved global popularity in comparison to other alternatives, such as phenols. It is popular in certain industrial applications due to various important factors. These are its environmental benefits, durability, water/oil resistance, anticorrosive behavior, and other valuable characteristics. Here, we will go through the features of Cardanol oil, its uses, and the manufacturing method in detail.
What is Cardanol?
Cardanol is a phenolic lipid that is simply extracted from anacardic acid, which is the key component of cashew nutshell liquid (CNSL). The Cashew Nutshell Liquid is a byproduct of cashew nut processing. Cardanol is mostly suitable in the chemical industry for resins, coatings, frictional materials, and surfactants that act as pigment dispersants in water-based inks.
In addition to the above, it is used to produce phenalkamines, which serve as curing agents for the long-lasting epoxy coatings that are generally used on concrete floors. The name of the material is short for the cashew tree name Anacardium occidentale.
The Different Uses of Cardanol Oil
Cardanol has various uses. The most significant one is its use in the chemical industry to make oil and alcohol-soluble resins, laminating resins, rubber compounding, and coatings. It is also a great raw material for producing high-quality insulating varnishes, paints, and enamels.
Apart from that, this oil is also used in friction materials and surfactants as pigment dispersants for water-based inks, as well as to produce phenalkamines. This acts as a curing agent for the long-lasting epoxy coatings used on concrete floors. Cardanol can replace Phenol by up to 30% in phenolic resins used as plywood bonding resin in the lamination industry.
A Brief Overview of Cardanol Oil Uses
Lamination Sector
One might make resins that give the lamination sheets more flexibility, resistance to chemicals and water, and superior electrical insulation by partially substituting phenol or cresol in alcohol-soluble resins used for lamination.
Adhesives
An excellent quality of Friction dust could be prepared from Cardanol which finds use in brake linings and Clutch facings.
Surface Paints and Coatings
Cardanol resin Varnishes have excellent air drying and baking qualities in addition to being water and chemically resistant. These materials are appropriate for wood finishes, food can lacquers, tax tile bobbins, and high-quality paints.
Medical Applications
Cardanol is an initiate material used in the production process of ointments, toothpaste, and eye care products. Moreover, cardanol is a terpene that can be found in essential oils. They also have excellent antioxidant qualities, making them ideal for combating skin and pancreatic malignancies.
Last Words
Until now, you must have understood Cardanol, a wonderful byproduct of Cashew Nut, and its unique characteristics. Cardanol has a multi-functional role that allows it to extract beneficial products from this incredible resource. In the chemical industry, cardanol is utilized in resins, coatings, friction materials, and surfactants that are used as pigment dispersants in water-based inks. Overall, it is a wonderful product that provides various benefits.
