Description

Soybean Oil, Polymer With Maleic Anhydride, Pentaerythritol And Phthalic Anhydride CAS NO 67762-15-6 is a modified alkyd resin derived from renewable soybean oil. This specialized polymer is engineered to offer a unique balance of flexibility, adhesion, and chemical resistance, making it a valuable intermediate for high-performance coatings. It is primarily sought after by formulators in the paints, coatings, and ink industries seeking sustainable and versatile resin solutions.

Application

• Industrial and Protective Coatings: As a key resin binder for metal primers, machinery enamels, and corrosion-resistant finishes.
• Architectural Paints: Used in the formulation of durable exterior and interior house paints, offering good weathering properties.
• Printing Inks: Serves as a vehicle resin for various ink systems, contributing to gloss and adhesion on substrates.
• Adhesives and Sealants: Acts as a tackifying or modifying agent to enhance flexibility and bond strength.
• Wood Finishes: Employed in varnishes and stains to provide a protective, flexible film.
• Specialty Polymers: Utilized as a polyol component or modifier in the synthesis of polyurethanes and other polymers.

Quality Control

Our production of this alkyd resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your formulation requirements.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat sources and open flame. For long-term storage, consider blanketing with an inert gas such as nitrogen.
