Description

Soybean Oil, Polymer With Ethylene Glycol, Glycerol, Maleic Anhydride, Pentaerythritol And Phthalic Anhydride CAS NO 67923-31-3 is a specialized alkyd resin derived from renewable soybean oil and key polyols and acids. This polymer is engineered to provide a versatile and sustainable base material for high-performance coatings and binders. It is essential for industrial manufacturers seeking to enhance product durability, flexibility, and environmental profile.

Application

• Industrial Coatings: As a primary resin in the formulation of air-drying and baking enamels for machinery, agricultural equipment, and metal substrates.
• Protective & Marine Coatings: Used in corrosion-resistant primers and topcoats for structural steel, bridges, and ship hulls due to its excellent adhesion and weather resistance.
• Architectural Paints: Serves as a key component in high-quality exterior house paints and trim paints, offering good gloss retention and durability.
• Printing Inks: Employed as a binder in specialty printing inks, contributing to gloss, rub resistance, and film formation.
• Adhesives & Sealants: Acts as a tackifying resin or film-forming agent in certain industrial adhesive and sealant formulations.
• Wood Finishes: Used in varnishes and stains for furniture and flooring, providing a clear, protective film with good penetration.

Quality Control

Our alkyd resins are manufactured under a strict 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. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which can affect product properties.
