Description

Fatty Acids, C18-Unsaturated, Dimers, Polymers With Hexamethylenediamine And Sebacic Acid is a high-performance polyamide resin derived from dimerized fatty acids and aliphatic diamines. This specialized polymer is engineered to provide exceptional flexibility, adhesion, and chemical resistance, making it a critical component in demanding industrial formulations. It is essential for manufacturers in the coatings, adhesives, and specialty plastics sectors seeking durable, high-quality polymer matrices.

Application

• Hot-Melt Adhesives (HMA): Acts as a key flexibilizing and tackifying agent, improving low-temperature performance and adhesion to difficult substrates.
• Industrial & Protective Coatings: Used in solvent-borne and powder coatings to enhance film flexibility, impact resistance, and corrosion protection.
• Printing Inks: Imparts excellent pigment wetting, gloss, and abrasion resistance in flexographic and gravure inks.
• Plastic Modification: Serves as a compatibilizer and impact modifier in engineering plastics and composites.
• Sealants and Caulks: Provides durable, flexible, and water-resistant properties in construction and automotive sealants.
• Can & Coil Coatings: Offers the necessary adhesion and formability for metal decorating and coil coating applications.

Quality Control

Our production of Fatty Acids, C18-Unsaturated, Dimers, Polymers With Hexamethylenediamine And Sebacic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistent performance characteristics such as amine value, acid value, viscosity, and softening point. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
