CNSL is a versatile industrial raw material with diverse use in friction linings, paints and varnishes, laminating and epoxy resins, foundry chemicals and as an intermediary of chemicals.
The shell liquid, which is extracted out of the outer shell of the nut, also has industrial applications in the automotive industry, leather, and tobacco curing.
CNSL-based derivatives have been used as substitute for phenol.and used in the making of resins for paints and foundry core oils, insulating varnishes and the like.
The shell liquid has been extensively distilled to produce Cardanol, which is used in the preparation of friction dust for brake linings and also in rubber compounding formulations.
CNSL has qualities replicating furnace oil. The potential as fuel gives it additional value and as a bio-fuel, it can compete with costlier petroleum products.
