Description

Linseed Oil Fatty Acids are a natural mixture of unsaturated fatty acids derived from linseed (flaxseed) oil, primarily consisting of linolenic, linoleic, and oleic acids. This product is valued for its high degree of unsaturation, which makes it a highly reactive and versatile chemical intermediate for industrial synthesis. It is essential for manufacturers in the coatings, polymer, and oleochemical industries seeking sustainable, bio-based raw materials for high-performance applications.

Application

• Alkyd Resins & Paints: A key raw material for producing air-drying and high-durability alkyd resins used in industrial and decorative coatings.
• Polymer Additives: Used in the synthesis of plasticizers, lubricants, and stabilizers for PVC and other polymers.
• Soaps & Detergents: Serves as a feedstock for manufacturing metallic soaps (driers) and surfactants.
• Bio-based Lubricants: An important component in formulating environmentally friendly lubricants and greases.
• Epoxy Ester Resins: Reacted with epoxy resins to create flexible, corrosion-resistant coatings for metal substrates.
• Chemical Intermediate: Used in further chemical reactions such as dimerization, amidation, and esterification to produce specialty chemicals.

Quality Control

Our Linseed Oil Fatty Acids are produced under a stringent quality management system. Each batch is tested to ensure consistent composition, acid value, iodine value, and color. A comprehensive Certificate of Analysis (COA) detailing purity, specifications, and test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C under an inert atmosphere (nitrogen blanket) to minimize oxidation. Keep away from strong acids, oxidizing agents, and heat sources. The product is easily oxidized; prolonged exposure to air should be avoided.
