Description

Castor Oil, Dehydrated, Polymer With Glycerol, Phthalic Anhydride And Soybean Oil is a specialized alkyd resin derived from renewable vegetable oils. This polymer is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance for demanding industrial formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and ink industries seeking sustainable and high-performance binder solutions.

Application

• Industrial Coatings: Used as a primary binder or modifying resin in air-drying and stoving enamels, providing excellent gloss retention and durability.
• Printing Inks: Serves as a key component in lithographic and specialty inks, contributing to pigment wetting, gloss, and adhesion on various substrates.
• Adhesives & Sealants: Imparts flexibility and water resistance to adhesive formulations for packaging, construction, and automotive applications.
• Wood Finishes: Enhances the depth of color and protective qualities in varnishes and wood stains.
• Metal Primers: Provides good corrosion inhibition and surface adhesion in primer coatings for metal protection.
• Plastic Coatings: Used in coatings for flexible plastics, offering necessary elasticity and chemical resistance.

Quality Control

Our production of this alkyd resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. Certificates of Analysis (COA) documenting all relevant specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skinning and maintain product integrity.
