Description

Castor Oil, Polymer With Glycerol And Phthalic Anhydride is a specialized alkyd resin derived from renewable castor oil, modified with glycerol and phthalic anhydride. This polymer is valued for its excellent film-forming properties, flexibility, and adhesion, making it a crucial component in high-performance coating systems. It is primarily sought by manufacturers in the paints and coatings, adhesives, and specialty polymers industries for formulating products that require durability and environmental resistance.

Application

• Industrial and Decorative Paints: Used as a film-forming resin in air-drying and baking enamels, providing gloss, flexibility, and good adhesion to various substrates.
• Protective Coatings: Serves as a base for corrosion-resistant primers and finishes for metal, wood, and concrete surfaces.
• Adhesives and Sealants: Imparts tack, cohesion, and water resistance in formulation of industrial adhesives and sealants.
• Printing Inks: Acts as a binder in specialty printing inks, contributing to gloss, rub resistance, and substrate adhesion.
• Electrical Insulation: Employed in the production of wire enamels and insulating varnishes due to its good dielectric properties.
• Textile and Leather Finishes: Used in coatings and finishes to provide a flexible, protective layer.

Quality Control

Our Castor Oil, Polymer With Glycerol And Phthalic Anhydride is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, solids content, and color to ensure consistency and performance for your specific application. Certificates of Analysis (COA) 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 at room temperature (15-25°C). Keep away from heat sources and open flame. Due to its nature, the product should be stored under conditions that minimize prolonged exposure to air to prevent skinning or oxidation in the container.
