Description

Soybean Oil, Polymer With Glycerol, Pentaerythritol And Phthalic Anhydride is a specialized alkyd resin derived from renewable soybean oil, modified with polyols and phthalic anhydride. This compound matters for its role as a versatile, bio-based polymeric intermediate that offers excellent film-forming properties and adhesion. It is primarily needed by manufacturers in the coatings, inks, and adhesive industries seeking sustainable alternatives to purely petroleum-derived resins. The product, CAS NO 66070-93-7, provides a balance of flexibility, durability, and drying characteristics.

Application

• Primary binder in industrial and architectural coatings, including primers, enamels, and varnishes.
• Key resin component for printing inks, contributing to gloss and rub resistance.
• Formulation base for adhesives and sealants requiring good substrate wetting.
• Modifier in wood finishes and furniture lacquers to enhance durability and appearance.
• Raw material for corrosion-resistant metal coatings.
• Intermediate in the production of specialty polymers and plasticizers.

Quality Control

Our Soybean Oil Alkyd Resin is manufactured under a rigorous quality management system. Each batch is tested against key parameters such as acid value, viscosity, solids content, and color to ensure consistent performance and batch-to-batch uniformity. We provide comprehensive Certificates of Analysis (COA) upon request, detailing all relevant specifications. Our production adheres to industry-standard practices suitable for industrial and coatings applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from strong acids, organic solvents, and sources of ignition. As the product can be easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage to maintain optimal properties. Keep containers tightly sealed when not in use to prevent skinning and moisture absorption.
