Offering strong hydrophobic performance, contamination resistance, and heat and aging resistance, it eliminates the need for silicone in end use, resulting in a completely repulpable product. Additionally, it offers the ability to reduce the environmental risks and burdens imposed by solvents or fluorine-based products. This polymer can be blended with other products, such as those shown in Figure 5, enabling the creation of unique release coating formulations for specific applications. Work is ongoing to leverage this new technology for more applications, widening the range of release strengths it can provide and further enabling the reduction and elimination of older technologies, allowing more environmentally preferred end use products to be developed.

A natural choice / Yun mi Kim in ADHESIVES & SEALANTS INDUSTRY (ASI), Vol. 24, N° 5 (05/2017)

Therefore, CNSL is a non-food chain product that would otherwise be disposed of. Cashew trees can grow abundantly in tropical conditions. One of the most commercially useful chemicals from CNSL is cardanol, a pentadecadienyl phenol with an aliphatic side chain that usually consists of a mixture of one, two, and three double bonds in a linear chain. This natural phenolic compound has interesting chemical structural features that enable a variety of chemical modifications to create bio-based monomers and polymers. Phenalkamine is one of most successful chemicals used in cashew nutshell liquid, along with phenalkamide, exhibiting good reactivity for fast and low-temperature cure and strong adhesion even to damp or poorly prepared surfaces. In addition, its long aliphatic side chain delivers excellent water resistance, corrosion protection and chemical resistance.
