Cardanol

Cardanol (CAS 37330-39-5) is a phenolic lipid derived from cashew nut shell liquid (CNSL), a bio-based alternative to petroleum-derived phenols in reactive polymer systems.

Where is Cardanol used?

• Coatings, adhesives and polymer formulations: reactive diluent, plasticizer and surface-active modifier
• Epoxy coatings and anticorrosion primers: cardanol-based hardeners improve film flexibility
• Adhesive and sealant formulators use it to reduce viscosity and enhance substrate wetting
• Phenolic resins and friction materials: plasticizing co-monomer that reduces brittleness in brake pads and clutch facings
• Lubricant additive producers incorporate it as a bio-derived base for metalworking fluids.

Good to know: Technical grade is the standard commercial form, with purity specifications typically defined by hydroxyl value and unsaturation content. Refined and distilled grades with tighter color and composition profiles are available for demanding coating and polymer applications.
