Description

Linseed Oil, Polymd. is a polymerized form of linseed oil, a naturally derived drying oil. This product is valued for its enhanced film-forming properties, faster drying times, and improved durability compared to its raw counterpart. It is a critical component for industrial manufacturers requiring high-performance, sustainable binders and coatings. Key industries that utilize this material include paints & coatings, printing inks, linoleum production, and wood finishing.

Application

• As a primary binder and film-former in alkyd resin formulations for industrial and architectural paints.
• As a key component in high-gloss, durable printing inks, particularly for lithographic and letterpress applications.
• In the manufacture of linoleum flooring as a resilient and natural binding agent.
• As a penetrating wood finish and sealant, providing protection and enhanced grain appearance for furniture and flooring.
• As a plasticizer and modifier in caulks, putties, and sealants to improve flexibility and adhesion.
• In the production of core oils for foundry sand molds in metal casting.
• As a raw material for the synthesis of various specialty polymers and resins.
