Description

Sunflower Oil/Phthalic Anhydride/Pentaerythritol/Eg Resin CAS NO 68131-36-2 is a specialized alkyd resin synthesized from sunflower oil, phthalic anhydride, and pentaerythritol. This formulation is engineered to provide a unique balance of flexibility, durability, and rapid drying properties, making it a high-performance binder for advanced coating systems. It is primarily required by manufacturers in the protective coatings, industrial paints, and specialty ink industries seeking sustainable and high-quality resin solutions.

Application

• Protective Industrial Coatings: Used as a primary resin in formulations for machinery, agricultural equipment, and structural steel coatings requiring excellent weather resistance.
• High-Performance Architectural Paints: Serves as a key component in exterior paints and primers, offering good adhesion and durability on various substrates.
• Specialty Printing Inks: Employed in the production of overprint varnishes and ink vehicles that demand fast setting and good gloss.
• Wood Finishes and Varnishes: Acts as a film-forming agent in clear and pigmented finishes for furniture and flooring, providing a hard, protective surface.
• Corrosion-Resistant Primers: Formulated into primers for metal surfaces, leveraging its good barrier properties and compatibility with anti-corrosive pigments.
• Adhesive and Sealant Modifiers: Used to modify the properties of adhesives and sealants, enhancing flexibility and bond strength.
