CNSL -Surface coatings

As raw material for surface coating
Surface coatings which are derived from Cashew nut shell liquid (CNSL) exhibit excellent lustre and surface finish with optimized levels of toughness and elastic properties. CNSL resins are impregnated into synthetics by paint manufacturing industries to modify the paint properties and to decrease the cost. It has anti-thermite and anti- microbial properties. Due to its darkish brown colour CNSL is used to make dark-colored paints and enamels. CNSL derivatives can also give a highly efficient performance as lacquers. The dry lacquer films are much better than the ordinary oil-based paints since the dry lacquers are resistant to oil damages, moisture damages and also resistant to any kind of chemical action. CNSL resins in combination with some other polymers can contribute to a good roof protection. Anti-corrosive polymers manufactured from the cashew nut shell liquid derivatives can be used as a protective lining for the bottoms of sea ships. Zinc incorporated CNSL polymers may be used as surface coatings which are rust-proof.
