Description

Cardanol Diene is a versatile, naturally derived chemical intermediate derived from cashew nut shell liquid (CNSL). This compound matters for its unique combination of a phenolic structure and a reactive diene functionality, offering a sustainable and reactive platform for polymer and resin synthesis. Industries such as specialty polymers, coatings, adhesives, and friction materials rely on it to develop bio-based, high-performance products.

Application

• Polymer Modification: Acts as a reactive diluent and modifier in phenolic, epoxy, and polyurethane resins to enhance flexibility and thermal stability.
• Coatings & Adhesives: Used in the formulation of bio-based, durable industrial coatings, varnishes, and adhesives.
• Friction Materials: A key component in the production of brake linings and clutch facings, contributing to performance and reduced wear.
• Surfactants & Emulsifiers: Serves as a hydrophobic building block for non-ionic surfactants and specialty emulsifiers.
• Chemical Synthesis: An intermediate for Diels-Alder reactions and other chemical transformations to create novel specialty chemicals.
• Rubber Compounding: Functions as a processing aid and plasticizer in rubber formulations.

Quality Control

Our Cardanol Diene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) and infrared spectroscopy (IR), to ensure consistent purity and performance. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve quality and shelf life. Keep away from strong oxidizing agents.
