Description

Castor Oil, Dehydrated, Polymer With Benzoic Acid, Isophthalic Acid, Terephthalic Acid And Trimethylolethane is a specialized, high-performance alkyd resin derived from renewable castor oil. This polymer is engineered to provide excellent film-forming properties, chemical resistance, and durability for demanding industrial coatings. It is a critical raw material for formulators seeking to enhance the performance and sustainability profile of their products. Key industries that utilize this advanced resin include high-end paints and coatings, industrial adhesives, and specialty polymers.

Application

• Primary resin for high-performance industrial and marine coatings requiring superior weather and chemical resistance.
• Key component in baking enamels and stoving finishes for automotive, appliance, and metal furniture applications.
• Binder for corrosion-resistant primers and undercoats on steel and other metal substrates.
• Formulation of high-gloss decorative paints with excellent flow, leveling, and adhesion properties.
• Base for specialty inks and overprint varnishes requiring fast drying and good film integrity.
• Modifier in adhesives and sealants to improve flexibility, toughness, and bond strength.
• Raw material for electrical insulation varnishes and other protective polymeric coatings.

Quality Control

Our Castor Oil, Dehydrated, Polymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including acid value, viscosity, solids content, and color to meet precise customer specifications. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment, ensuring full traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, and open flame. Due to its nature as an easily oxidized material, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage to prevent skinning and gelation. Keep containers tightly sealed when not in use to prevent moisture absorption and contamination.
