Description

Castor Oil, Dehydrated, Polymer With p-tert-Butylbenzoic Acid, Glycerol And Phthalic Anhydride is a specialized alkyd resin derived from renewable castor oil. This modified polymer offers a unique balance of properties, including excellent adhesion, flexibility, and chemical resistance, making it a valuable component in high-performance coatings and adhesives. It is primarily sought after by formulators in the paints, coatings, inks, and specialty adhesive industries who require bio-based or tailored resin solutions.

Application

• Industrial and Protective Coatings: As a film-forming resin in primers, topcoats, and maintenance paints for metal, wood, and concrete substrates.
• Specialty Inks: Used as a binder in flexographic and gravure printing inks, contributing to gloss and adhesion.
• Adhesives and Sealants: Serves as a key polymeric component to enhance tack, cohesion, and environmental resistance.
• Electrical Insulating Varnishes: Employed in wire enamels and impregnating resins due to its good dielectric properties and thermal stability.
• Modifier for Other Polymers: Used to plasticize or improve the flexibility and adhesion of other resin systems like phenolics or epoxies.

Quality Control

Our production of this alkyd resin adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment to support your quality assurance processes.

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). Keep away from strong acids and organic solvents. For long-term storage, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
