Description

Castor Oil, Dehydrated, Polymer With Linseed Oil, Pentaerythritol, Phthalic Anhydride And Polymd. Linseed Oil is a specialized alkyd resin derived from the polymerization of dehydrated castor oil and linseed oil with pentaerythritol and phthalic anhydride. This engineered polymer offers a unique balance of flexibility, adhesion, and chemical resistance, making it a critical component in high-performance industrial coatings. It is primarily utilized by formulators in the paints, varnishes, and specialty coatings industries seeking to enhance the durability and drying properties of their products. CAS No. 68154-16-5.

Application

• Industrial and Maintenance Coatings: As a primary resin binder in air-drying and baking enamels for machinery, agricultural equipment, and structural steel.
• Marine and Protective Coatings: Formulating anti-corrosive primers and topcoats that require excellent water resistance and adhesion to metal substrates.
• Printing Inks: Used in specialty overprint varnishes and ink vehicles to improve gloss, rub resistance, and drying speed.
• Wood Finishes: A key component in varnishes, stains, and sealers for furniture and flooring, providing a durable, protective film.
• Adhesives and Sealants: Imparts flexibility and binding strength in certain industrial adhesive formulations.
• Primers: Serves as an effective base coat resin, promoting adhesion of subsequent coating layers to various surfaces.
