Cashew Nut Shell Liquid (CNSL) is a high-value industrial byproduct extracted from the shell of cashew nuts. With growing demand in global manufacturing, CNSL plays a vital role in automotive, chemical, and construction industries.

πŸ‘‰ SVC Cashew is a trusted supplier of bulk CNSL from Vietnam, offering both crude and refined forms with reliable capacity and export documentation.

πŸ§ͺ What is CNSL?

CNSL is a dark brown viscous liquid containing natural phenolic compounds:

  • Anacardic Acid (60–70%)
  • Cardol (15–20%)
  • Cardanol (5–10%)
  • Trace methyl cardol and other alkenyl phenols

Its molecular structure provides friction-reducing, polymerizing, and anti-corrosive properties.

βš™οΈ Extraction Process

SVC uses two industrial extraction methods:

πŸ”₯ Hot Oil Bath – Heats shells at ~190–200Β°C to release CNSL

πŸ”§ Mechanical Expression – Crushes roasted shells to extract CNSL

🧹 Optional refinement or filtration available as per request

🏭 Industrial Applications

CNSL is widely used in:

  • πŸš— Automotive: Brake linings, clutch facings, friction dusts
  • 🧴 Coatings & Paints: Marine paint, varnish, epoxy primer
  • 🧱 Construction: Sealants, resin flooring, epoxy compounds
  • πŸ’‘ Electronics: Insulating lacquers, circuit laminates
