Description

Castor Oil, Polymer With Azelaic Acid, Glycerol And Phthalic Anhydride CAS NO 68783-28-8 is a specialized alkyd resin derived from renewable castor oil, modified with azelaic acid and phthalic anhydride. This polymer offers a unique balance of flexibility, adhesion, and chemical resistance, making it a valuable component for high-performance formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and polymer modification industries seeking bio-based or enhanced-performance additives.

Application

As a flexibilizing and adhesion-promoting resin in industrial and protective coatings.
As a modifier for epoxy and polyester systems to improve impact resistance and reduce brittleness.
In the formulation of specialty adhesives and sealants requiring good chemical and moisture resistance.
As a bio-based polymeric plasticizer for PVC and other polymer systems.
In the production of printing inks to enhance gloss, flow, and substrate adhesion.
For manufacturing corrosion-resistant primers and metal coatings.
As an intermediate for further chemical synthesis of more complex polymeric materials.

Quality Control

Our production of Castor Oil, Polymer With Azelaic Acid, Glycerol And Phthalic Anhydride adheres to stringent quality management protocols. Each batch is tested against key parameters such as acid value, viscosity, and color to ensure consistency and performance for your applications. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment.

Storage

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