Description

Fatty Acids, Tall-Oil, Polymers With Benzoic Acid, Ethylene Glycol, Glycerol And Phthalic Anhydride CAS NO 121053-21-2 is a specialized polymeric resin synthesized from tall oil fatty acids, a renewable resource, and other key monomers. This complex polymer is engineered to provide a unique combination of flexibility, adhesion, and chemical resistance, making it a valuable intermediate for high-performance formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• As a key resin component in alkyd coatings for industrial and architectural applications, enhancing durability and gloss.
• Formulation of high-strength structural and specialty adhesives for wood, metal, and composite bonding.
• Production of plasticizers and modifiers to improve the flexibility and impact resistance of polymers like PVC.
• Manufacture of printing inks, where it contributes to pigment wetting and film-forming properties.
• As a reactive intermediate in the synthesis of polyester polyols for polyurethane foams and elastomers.
• Development of corrosion-resistant primers and sealants for automotive and marine industries.

Quality Control

Our production of this polymeric resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and hydroxyl value are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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 away from incompatible materials such as 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.
