Abstract:
Cashenut nutshell liquid is a versatile byproduct of the cashew industry. The oil is
obtained from the spongy layer (pericarp) between the inner and outer shell of cashew
nuts. It is extensively used in the manufacture of superior type of paints, insulating
varnishes in the electrical industry, special types of adhesive cement, brake linings,
phenolic resins etc. CNSL is an important ingredient for special types of paints and
insulating varnishes. Cashew shell liquid produced by solvent extraction is of very
high quality but due to irregular nature of raw material it is not viable, however
expeller process of oil extraction is suitable.
