Description

Castor Oil, Dehydrated, Polymer With Ethylene Glycol, Glycerol And Phthalic Anhydride is a specialized alkyd resin derived from renewable castor oil, offering a unique combination of flexibility, adhesion, and chemical resistance. This polymer is engineered to provide superior performance as a film-forming agent and reactive intermediate in demanding industrial formulations. It is essential for manufacturers in the coatings, adhesives, and polymer industries seeking bio-based or high-performance resin components.

Application

• Industrial Coatings: As a key resin component in high-flexibility, corrosion-resistant primers, enamels, and maintenance paints.
• Adhesives & Sealants: To enhance tack, adhesion, and flexibility in structural and pressure-sensitive adhesive formulations.
• Polymer Modification: As a plasticizer or co-polymer to improve the impact resistance and flexibility of rigid polymers.
• Printing Inks: Used in flexographic and gravure inks to promote substrate wetting and film formation.
• Electrical Insulation: In the formulation of wire enamels and insulating varnishes requiring thermal stability and dielectric strength.
• Foundry Core Binders: As a binding resin in sand cores for metal casting processes.

Quality Control

Our Castor Oil, Dehydrated, Polymer is produced under a stringent quality management system. Each batch is tested against key parameters including acid value, viscosity, color, and solids content to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong alkalis and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame.
