Description

1,3-Isobenzofurandione, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol, 1,2-Propanediol And 1,2,3-Propanetriol, Benzoate (Z,Z)-9,12-Octadecadienoate is a specialized polymeric ester derived from phthalic anhydride, polyols, and linoleic acid, designed to offer unique performance characteristics. This complex polymer is engineered to provide enhanced flexibility, adhesion, and compatibility in advanced coating and resin formulations. It is a critical raw material for industrial manufacturers seeking to develop high-performance, durable products with specific rheological and film-forming properties.

Application

• Advanced Industrial Coatings: As a key resin modifier or primary binder in high-performance protective and decorative coatings, offering improved flexibility and adhesion to various substrates.
• Specialty Inks and Adhesives: Used in the formulation of flexographic and gravure inks, as well as pressure-sensitive adhesives, where its polymeric structure contributes to tack and binding strength.
• Polymer Plasticizers and Modifiers: Acts as a polymeric plasticizer or compatibilizer in PVC, polyurethanes, and other polymer systems to enhance processability and final product properties.
• Composite Materials: Serves as a matrix resin or additive in fiber-reinforced composites and laminates, improving interlaminar bonding and impact resistance.
• Release Coatings and Liners: Utilized in the production of release papers and films for labels and tapes due to its film-forming and surface-active characteristics.

Quality Control

Our production of this specialty polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and oxidation. Keep away from heat sources and incompatible materials.
