Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Benzoic Acid, Ethylenediamine, Propionic Acid And Triethylenetetramine CAS NO 68989-69-5 is a complex, high-performance polyamide resin intermediate derived from dimerized unsaturated C18 fatty acids. This specialized chemical is engineered to provide exceptional adhesion, flexibility, and chemical resistance in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and ink industries seeking to enhance the performance and durability of their final products.

Application

• Corrosion-Resistant Industrial Coatings: Serves as a key building block for polyamide resins used in high-performance protective coatings for marine, automotive, and infrastructure applications.
• Flexographic and Gravure Inks: Used in the synthesis of resins that provide excellent pigment wetting, gloss, and adhesion to flexible substrates like films and foils.
• Structural and Assembly Adhesives: Imparts toughness and thermal stability to polyamide-based adhesives for bonding metals, plastics, and composites.
• Can and Coil Coatings: A vital component in resins formulated for coatings that require superior formability, adhesion, and resistance to chemicals and weathering.
• Overprint Varnishes: Enhances the scuff resistance, gloss, and protective properties of varnishes applied over printed materials.
• Epoxy Curing Agents & Modifiers: Acts as a reactive modifier or curing agent for epoxy systems, improving flexibility and impact resistance.

Quality Control

Our production of this polyamide intermediate 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 color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and open flame.
