Description

Fatty Acids, Tall-Oil, Polymers With Benzoic Acid, Isononanoic Acid, 9,11-Linoleic Acid, 10,12-Linoleic Acid, Pentaerythritol And Phthalic Anhydride is a complex, synthetic polyester resin derived from a blend of fatty acids and polybasic acids. This specialized polymer is engineered to offer enhanced flexibility, adhesion, and chemical resistance compared to standard alkyd or polyester resins. It serves as a critical raw material for formulators in the coatings and adhesives industries seeking high-performance, modified resin systems. CAS No. 71011-21-7.

Application

• High-Performance Industrial Coatings: Used as a resin modifier in air-drying and baking enamels for machinery, agricultural equipment, and metal substrates, providing excellent durability and gloss retention.
• Protective & Marine Coatings: Imparts superior water resistance and flexibility in primers and topcoats for marine vessels, offshore structures, and corrosion-prone environments.
• Specialty Adhesives & Sealants: Acts as a key polymeric component in formulating structural adhesives, pressure-sensitive adhesives (PSAs), and elastic sealants requiring strong adhesion and weatherability.
• Printing Inks: Serves as a binder in specialty printing inks, particularly overprint varnishes and inks for flexible packaging, enhancing rub resistance and film properties.
• Plasticizers & Modifiers: Functions as a polymeric plasticizer or compatibilizer in PVC and other polymer blends to improve flexibility and processing characteristics.
• Wood Finishes: Incorporated into varnishes and stains for furniture and flooring to achieve a tough, protective film with good penetration and clarity.

Quality Control

Our production of this specialty polyester resin adheres to strict quality management systems to ensure batch-to-batch consistency. Key parameters such as acid value, viscosity, color, and solids content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with each shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider blanketing with an inert gas such as nitrogen to prevent skin formation and oxidative degradation.
