Description

Soybean Oil, Polymer With p-tert-Butylbenzoic Acid, Glycerol, Pentaerythritol And Phthalic Anhydride CAS NO 68309-73-9 is a specialized alkyd resin derived from renewable soybean oil, modified with a unique blend of polyols and acids to create a high-performance polymeric material. This product matters for formulators seeking a versatile, bio-based resin component that offers excellent film-forming properties, adhesion, and flexibility. It is needed by manufacturers in the coatings, adhesives, and ink industries who require sustainable raw materials without compromising on performance.

Application

• As a primary film-forming resin in industrial and decorative coatings, providing durability and gloss.
• As a key component in high-performance printing inks, contributing to pigment wetting and substrate adhesion.
• As a polymeric plasticizer or modifier in adhesive and sealant formulations to enhance flexibility and bond strength.
• In the production of specialty polymers and composites where bio-based content and specific rheological properties are required.
• As a binder in wood finishes and varnishes, offering good penetration and a protective film.
• For formulating corrosion-resistant primers and metal coatings due to its good adhesion to metallic substrates.

Quality Control

Our Soybean Oil Polymer is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in viscosity, acid value, color, and solids content, meeting the stringent requirements of industrial resin applications. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning or changes in viscosity.
