Description

Linseed Oil, also known as flaxseed oil, is a natural drying oil derived from the seeds of the flax plant (Linum usitatissimum). Its unique chemical composition, rich in polyunsaturated fatty acids like linolenic acid, makes it a crucial raw material for industries requiring durable, protective coatings and binders. This versatile oil is essential for manufacturers in the paints & coatings, inks, linoleum, and wood treatment sectors seeking sustainable, high-performance ingredients.

Application

• Paints, Varnishes, and Coatings: A fundamental component in oil-based paints and varnishes, where it polymerizes to form a tough, flexible, and protective film.
• Printing Inks: Used as a vehicle in lithographic and specialty printing inks, contributing to gloss, drying properties, and adhesion.
• Linoleum Flooring: Acts as the primary binder, oxidized to create a resilient and elastic backing material for floor coverings.
• Wood Finishing and Preservation: Applied as a traditional wood finish to enhance grain appearance and provide a protective layer against moisture.
• Putty and Caulking Compounds: Serves as a plasticizer and binder, ensuring long-lasting flexibility and adhesion in sealants.
• Artist's Materials: A key medium in oil painting, valued for its clarity, yellowing resistance over time, and blending properties.
• Industrial Lubricants and Plasticizers: Employed in environmentally friendly lubricants and as a bio-based plasticizer in certain polymer applications.

Quality Control

Our Linseed Oil is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and performance. Key parameters such as acid value, iodine value, peroxide value, and saponification value are rigorously monitored. A Certificate of Analysis (COA) detailing these specifications 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 temperatures between 15-25°C (59-77°F). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., nitrogen blanket) is recommended to preserve quality and prevent rancidity. Keep away from heat sources and open flames.
