Description

Decanedioic Acid, Polymer With 1,2-Ethanediamine, 1,6-Hexanediamine And (Z,Z)-9,12-Octadecadienoic Acid Dimer is a specialized polyamide resin derived from sebacic acid, diamines, and a dimer acid. This engineered polymer is valued for its unique balance of flexibility, thermal stability, and chemical resistance, making it a critical performance component in advanced formulations. It is primarily sought by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and functionality.

Application

• High-Performance Coatings and Inks: Acts as a film-forming agent and modifier to improve flexibility, adhesion, and chemical resistance in industrial, automotive, and protective coatings.
• Hot-Melt and Reactive Adhesives: Provides excellent bonding strength, thermal stability, and substrate wetting properties for demanding assembly applications.
• Engineering Plastics and Composites: Used as a toughening agent or compatibilizer to enhance the impact resistance and mechanical properties of nylon and other polyamide blends.
• Printing and Overprint Varnishes: Imparts gloss, rub resistance, and durability to finishes applied to packaging and printed materials.
• Leather and Textile Finishing: Serves as a durable, flexible resin binder for topcoats and treatments requiring excellent hand feel and resistance to cracking.
• Sealants and Caulks: Contributes to long-term elasticity, adhesion, and weather resistance in construction and automotive sealant formulations.

Quality Control

Our production of this polyamide resin adheres to strict quality management systems. 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 provided and available upon request 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties.
