Description

Soybean Oil,Polymer With Glycerol,Pentaerythritol,Phthalic Anhydride,Styrene And Vinyltoluene CAS NO 68390-87-4 is a specialized alkyd resin derived from modified soybean oil, offering a sustainable and versatile polymeric backbone. This compound is engineered to provide excellent film-forming properties, adhesion, and flexibility, making it a crucial component in high-performance coating formulations. It is primarily sought by manufacturers in the paints, coatings, and industrial resin sectors for developing eco-friendlier, durable finishes.

Application

• As a primary film-forming resin in industrial and architectural paints and coatings.
• Formulation of high-solids and solvent-borne coatings for enhanced durability and gloss.
• Key component in corrosion-resistant primers and metal coatings.
• Binder for wood finishes and varnishes, providing excellent penetration and protection.
• Used in printing inks to improve adhesion and rub resistance.
• Base for specialty adhesives and sealants requiring flexible, strong bonds.
• Modifier in plastic composites to enhance impact resistance and surface properties.

Quality Control

Our Soybean Oil Alkyd Resin is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through rigorous testing of key parameters including acid value, viscosity, solids content, and color. Certificates of Analysis (COA) documenting full specifications are available for every shipment upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from strong alkalis and incompatible organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skinning and maintain product integrity.
