Description

Castor Oil, Dehydrated, Polymer With Oleic Acid, Phthalic Anhydride, Soybean Oil And Trimethylolpropane is a specialized alkyd resin intermediate derived from a co-polymerization reaction of key natural oil derivatives and polyols. This compound matters for its role in formulating high-performance, modified alkyd resins that offer enhanced drying properties, flexibility, and adhesion. Industrial manufacturers in the coatings, inks, and adhesive sectors need this product to develop advanced, durable finishes for a variety of substrates.

Application

• Primary resin component in the formulation of air-drying and baking alkyd coatings for industrial and architectural applications.
• Modifier for printing inks to improve gloss, flow, and pigment wetting.
• Key intermediate in the production of specialty adhesives and sealants requiring good flexibility and chemical resistance.
• Base for corrosion-resistant primers and metal coatings.
• Raw material for manufacturing plasticizers and compatibilizers for polymer blends.
• Used in wood finishes and varnishes to enhance durability and drying speed.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for resin intermediates. Key parameters such as acid value, viscosity, color, and solids content are monitored against strict internal specifications. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat sources and open flames. Due to its nature, prolonged exposure to air should be minimized to prevent skinning or oxidation.
