Description

Soybean Oil, Polymer With Fumaric Acid, Pentaerythritol And Phthalic Anhydride CAS NO 67762-11-2 is a high-performance alkyd resin intermediate derived from renewable soybean oil. This specialized polymer is valued for its ability to impart flexibility, adhesion, and durability to final coating formulations. It is an essential raw material for manufacturers in the paints, coatings, inks, and adhesives industries seeking to enhance product performance.

Application

• Alkyd Resin Production: A key intermediate for manufacturing air-drying and baking alkyd resins used in industrial and decorative paints.
• Protective Coatings: Used in corrosion-resistant primers and topcoats for metal substrates, machinery, and structural steel.
• Printing Inks: Serves as a resin component in offset and lithographic printing inks, providing gloss and rub resistance.
• Adhesive Formulations: Imparts tack and flexibility in certain pressure-sensitive and laminating adhesives.
• Wood Finishes: Incorporated into varnishes and stains to improve penetration, drying time, and film formation.
• Specialty Polymers: Acts as a polyol component or modifier in the synthesis of other polymer systems for enhanced properties.

Quality Control

Our production of Soybean Oil Polymer adheres to stringent quality management protocols. Each batch is characterized for critical parameters such as acid value, viscosity, color, and solids content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
