Cashew Nut Shell Liquid

Cashew Nut Shell Liquid (CNSL)

Vili Organics’ Cashew Nut Shell Liquid (CNSL) is a natural, renewable, and high-performance industrial raw material extracted from the shells of Anacardium occidentale (cashew nuts). It is a phenolic lipid compound comprising primarily anacardic acid, cardanol, and cardol, offering exceptional chemical reactivity and versatility. CNSL serves as a sustainable substitute for petroleum-based phenols in coatings, resins, adhesives, and friction materials.

Key Features:


  • Extracted from cashew nut shells via controlled thermal or solvent extraction
  • Rich in cardanol, cardol, and anacardic acid — reactive phenolic compounds
  • Excellent thermal stability, chemical resistance, and lubrication properties
  • 100% natural and bio-based alternative to petrochemical phenols
  • Suitable for industrial, chemical, and specialty applications
  • Available in multiple grades — Raw CNSL, Technical CNSL, and Distilled CNSL (Cardanol-rich)


Applications:


  • Resins & Coatings: Used in phenolic resins, epoxy hardeners, and surface coatings
  • Adhesives & Sealants: Enhances bonding strength and water resistance
  • Friction Materials: Widely used in brake linings, clutch facings, and automotive pads
  • Lubricants & Additives: Provides natural oxidation stability and anti-wear protection
  • Polymers & Paints: Acts as a flexible modifier improving impact resistance
  • Biofuel & Chemical Intermediates: Precursor for synthesizing bio-based chemicals and surfactants

Cardanol
(Distilled CNSL)

Vili Organics’ Cardanol is a high-purity phenolic lipid derived from distilled Cashew Nut Shell Liquid (CNSL) obtained from Anacardium occidentale. Cardanol is an excellent bio-based phenolic compound, valued for its reactive phenolic group and long aliphatic side chain, which together provide exceptional flexibility, hydrophobicity, thermal stability, and chemical resistance.
It is widely used in epoxy curing agents, phenolic resins, adhesives, surface coatings, and friction materials, serving as a sustainable alternative to petrochemical phenols.

Cardanol

Key Features:

  • Excellent chemical reactivity for resin synthesis
  • Superior thermal stability and long-chain flexibility
  • Low volatility and excellent hydrophobicity
  • Outstanding electrical insulation and corrosion resistance
  • Eco-friendly, biodegradable phenolic compound









Applications:


  • Epoxy Curing Agents: Improves flexibility, impact strength, and chemical resistance
  • Phenolic & Alkyd Resins: Used in heat-resistant and corrosion-resistant coatings
  • Paints & Coatings: Enhances gloss, adhesion, and weatherability
  • Friction Materials: Applied in brake pads and clutch linings for heat resistance
  • Adhesives & Sealants: Provides superior bonding and water resistance
  • Polymer Modifiers: Improves impact, toughness, and anti-corrosion behavior
  • Anti-corrosive Primers: Used in marine and industrial-grade coatings
