Novalac CNSL formaldehyde resins have long hydrocarbon chains therefore the condensates are more flexible than the conventional phenolic resins. The presence of aromatic and phenolic compounds enables CSNL to cross-link with formaldehyde to form novalac and resole which are usable thermoset resins for biocomposites. A hexamethylenetetramine (HMTA) hardener is added to CNSL-formaldehyde resins as a way of improving the cure characteristics.

The different constituents of CNSL, as aromatic, phenolic compounds, can react with formaldehyde to create condensation polymers, such as resole and novolac, which make excellent matrix resins for composites and also the unsaturation sites in the side chains of CNSL can also undergo addition polymerization using either free radical initiators or ionic initiators. The presence of aromatic rings in CSNL is an added advantage which results into thermal stability, making it to be used as a fire retardant. In the industry, CNSL is extracted by an automated process that employs high temperatures in order to open the shell and recover the cashew kernel. Nowadays, with the advances in the chemistry of these phenolic lipids, tCNSL appears as an economically feasible source of phenolic components. Technical CNSL was employed as a source of phenolic compounds for the synthesis of phenol/formaldehyde polymers. Natural CNSL is obtained by the utilization of some solvent extraction technique (commonly soxhlet, supercritical carbon dioxide, or subcritical water) in order to obtain its constituents under mild conditions, without promoting any chemical modification. The composition of CNSL can vary based on the method used for extraction, and hence they have different chemical composition which can be classified into two main types: solvent-extracted CNSL (natural CNSL) and technical CNSL (tCNSL).
