Description

Fatty acids, tall-oil, polymers with bisphenol A, epichlorhydrin, ethylene-manuf.-by-product dicyclopentadiene-conc. alkenes, ethylene-manuf.-by-product piperylene-cut alkenes and maleic anhydride CAS NO 139168-80-2 is a specialized, high-performance synthetic resin derived from a complex polymerization of tall oil fatty acids, bisphenol A, epichlorohydrin, and specific hydrocarbon streams from ethylene manufacturing. This engineered polymer offers a unique combination of chemical resistance, adhesion, and flexibility, making it a critical formulation component. It is primarily used by industrial manufacturers seeking to enhance the durability and performance characteristics of their end products. Its tailored structure provides superior compatibility and functionality in demanding coating and adhesive systems.

Application

• High-Performance Industrial Coatings: Used as a resin modifier in protective coatings for metal, concrete, and pipelines, providing excellent corrosion resistance and adhesion.
• Adhesives and Sealants: Serves as a key polymeric backbone in structural and specialty adhesives, offering strong bonding and flexibility.
• Inks and Printing Materials: Acts as a resin component in specialty printing inks, contributing to gloss, rub resistance, and substrate adhesion.
• Composite Materials: Utilized as a matrix resin or toughening agent in fiber-reinforced composites for automotive and construction applications.
• Electrical Encapsulation: Employed in potting compounds and encapsulants for electronic components due to its insulating properties and chemical stability.
• Marine and Anti-fouling Coatings: A valuable component in marine coating formulations that require long-term durability in harsh, saline environments.

Quality Control

Our production of this advanced polymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, and color are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. While this product is typically manufactured to industrial grade standards, our quality system is designed to support compliance with relevant global regulatory frameworks for industrial chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flames. Under these conditions, the product is stable for extended periods. Ensure containers are kept sealed when not in use to prevent moisture absorption and skin formation.
