Description

C18-Unsaturated, Dimers, Hydrogenated, Polymers With Azelaic Acid And Ethylenediamine is a high-performance polyamide resin derived from dimerized fatty acids, azelaic acid, and ethylenediamine. This specialized polymer is valued for its excellent flexibility, adhesion, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily sought by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Flexographic and Gravure Inks: Acts as a key binder and grinding resin, providing excellent pigment wetting, gloss, and adhesion to flexible substrates like films and foils.
• Industrial & Packaging Adhesives: Used in hot-melt and solvent-based adhesive formulations to deliver strong bonds with good flexibility and heat resistance.
• Protective & Can Coatings: Imparts flexibility and adhesion in coatings for metal containers, coil coatings, and general industrial maintenance paints.
• Overprint Varnishes: Enhances scuff resistance, gloss, and lay-flat properties in protective topcoats for printed materials.
• Plastic Modification: Employed as a compatibilizer or impact modifier to improve the toughness and flexibility of engineering plastics.
• Sealants and Caulks: Contributes to the elasticity, adhesion, and durability of non-hardening sealant formulations.

Quality Control

Our production of this polyamide resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as amine value, acid value, viscosity, and softening point are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance processes.

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); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect product properties.
