Abstract
Considering ecological and economical issues in the new generation coating industries the maximum utilization of naturally occurring materials for polymer synthesis can be an obvious option In the same line one of the promising candidates for substituting partially and to some extent totally petroleumbased raw materials with an equivalent or even enhanced performance properties is the Cashew Nut Shell Liquid CNSL This dark browncolored viscous liquid obtained from shells of the cashew nut can be utilized for a number of polymerization reactions due to its reactive phenolic structure and a metasubstituted unsaturated aliphatic chain Therefore a wide variety of resins can be synthesized from CNSL such as polyesters phenolic resins epoxy resins polyurethanes acrylics vinyl alkyds etc The present article discusses the potential of CNSL and its derivatives as an environment friendly alternative for petroleumbased raw materials as far as polymer and coating industries are concerned
