Description

Soybean Oil, Polymer With Maleic Anhydride, Pentaerythritol And Vinyltoluene CAS NO 67923-37-9 is a specialized alkyd resin intermediate derived from renewable soybean oil, modified with maleic anhydride, pentaerythritol, and vinyltoluene. This engineered polymer offers a unique combination of flexibility, adhesion, and chemical resistance, making it a valuable component for high-performance coatings and adhesives. It is primarily sought by formulators in the industrial coatings, printing inks, and specialty polymer industries seeking to enhance product durability and sustainability profiles.

Application

• Industrial Coatings Binder: Used as a key resin component in air-drying and baking enamels for metal substrates, providing excellent adhesion and corrosion resistance.
• Printing Ink Vehicle: Serves as a modifying resin in lithographic and gravure inks to improve gloss, rub resistance, and pigment wetting.
• Adhesive Formulation: Imparts tack and flexibility in pressure-sensitive and structural adhesive systems.
• Overprint Varnish Modifier: Enhances the scuff resistance and gloss of protective varnishes for packaging materials.
• Primer Component: Utilized in corrosion-inhibiting primers for automotive and marine applications due to its good substrate wetting.
• Wood Coating Resin: Contributes to the flexibility and durability of coatings for furniture and flooring.

Quality Control

Our production of Soybean Oil, Polymer With Maleic Anhydride, Pentaerythritol And Vinyltoluene adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested against established internal specifications. Certificates of Analysis (COA) documenting these results are available for every shipment 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). This product is sensitive to strong acids and organic solvents and is easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage to maintain optimal properties. Keep away from heat, sparks, and open flame.
