Description

Castor Oil, Dehydrated, Polymer With Glycerol, Me Methacrylate, Pentaerythritol, Phthalic Anhydride And Styrene CAS NO 68082-07-5 is a specialized, high-performance alkyd resin derived from dehydrated castor oil and other key monomers. This engineered polymer offers a unique balance of flexibility, chemical resistance, and excellent adhesion properties, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty chemical industries for producing durable, high-quality finishes and binders.

Application

• Industrial Coatings: A key resin for high-performance air-drying and baking enamels, providing excellent gloss, adhesion, and durability for machinery, agricultural equipment, and metal substrates.
• Protective & Marine Coatings: Used in formulations requiring superior resistance to water, chemicals, and corrosion for bridges, ships, and offshore structures.
• Automotive Refinish Paints: Imparts flexibility and impact resistance in primer-surfacers and topcoats for automotive repair and refinishing applications.
• Adhesives and Sealants: Serves as a tackifying and binding agent in structural adhesives and elastomeric sealants, enhancing cohesion and environmental resistance.
• Printing Inks: Utilized in specialty ink vehicles for its fast setting properties, gloss, and pigment wetting characteristics.
• Wood Finishes: Formulated into varnishes and stains to provide a tough, protective film with good penetration and clarity.
• Electrical Insulating Varnishes: Applied in wire enamels and impregnating resins due to its good dielectric properties and thermal stability.

Quality Control

Our production of this specialized alkyd resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested. Certificates of Analysis (COA) documenting all relevant specifications 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 away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
