Description

Cardanol CAS NO 37330-39-5 is a naturally derived phenolic lipid obtained from cashew nut shell liquid (CNSL). This versatile bio-based intermediate is valued for its unique chemical structure, which imparts properties such as flexibility, water resistance, and inherent reactivity. It is a critical raw material for manufacturers in the polymer, coating, and specialty chemical industries seeking sustainable and high-performance alternatives to petrochemicals.

Application

• Epoxy Curing Agents & Modifiers: Used to formulate flexible, chemically resistant, and low-viscosity curing agents for epoxy resin systems in coatings, adhesives, and composites.
• Phenolic Resins: Serves as a renewable modifier for phenol-formaldehyde resins, improving flexibility, impact resistance, and flow properties in friction materials, laminates, and molding compounds.
• Surface Coatings & Paints: Employed in the synthesis of alkyds, polyurethanes, and other binders to enhance durability, adhesion, and water resistance in industrial and marine coatings.
• Friction Materials: A key component in brake pad and clutch facing formulations, contributing to stable friction performance and reduced noise.
• Surfactants & Emulsifiers: The hydrophobic alkyl chain enables its use in the production of non-ionic surfactants for various industrial applications.
• Rubber & Polymer Additives: Acts as a plasticizer, antioxidant, or processing aid in rubber compounding and polymer blends.
