Cardanol is widely used in the production of resins, coatings, and polymers due to its unique chemical structure and properties. It serves as a key raw material in the manufacture of phenalkamine curing agents, which are essential for epoxy coatings in marine and industrial environments. Its natural origin makes it an eco-friendly alternative to petroleum-based products.

In the polymer industry, cardanol is utilized to enhance the flexibility, durability, and thermal stability of materials. It is also incorporated into rubber compounding to improve processing and performance characteristics. Additionally, cardanol finds applications in the development of friction materials, such as brake linings and clutch facings, due to its heat resistance and binding properties.

Its surfactant properties make it suitable for use in emulsifiers and dispersants in various industrial processes. Furthermore, cardanol is employed in the synthesis of bio-based plasticizers, offering a sustainable option for the plastics industry. Its versatility and renewable nature make it a valuable component in advancing green chemistry and sustainable material solutions.
