Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine, 2-Ethylhexanoic Acid And Tall-Oil Fatty Acids CAS NO 68552-05-6 is a complex, high-performance polyamide resin derived from dimerized and polymerized unsaturated C18 fatty acids. This specialized chemical is engineered to provide exceptional adhesion, flexibility, and chemical resistance in demanding formulations. It is a critical component for manufacturers in the coatings, adhesives, and ink industries seeking to enhance the durability and performance of their products.

Application

• Corrosion-Resistant Industrial Coatings: Acts as a key binder and curing agent in high-performance epoxy and polyamide coatings for metal protection in marine, automotive, and infrastructure applications.
• High-Strength Structural Adhesives: Used as a reactive polyamide hardener in two-component epoxy adhesives for construction, aerospace, and automotive assembly, providing strong, flexible bonds.
• Printing Inks: Serves as a versatile resin for solvent-based and overprint varnishes, offering excellent gloss, adhesion to various substrates, and rub resistance.
• Sealants and Caulks: Imparts flexibility, adhesion, and moisture resistance in polyamide-based sealants used in construction and automotive applications.
• Foundry Resins: Functions as a core binder in cold-box and no-bake foundry processes for metal casting, providing good shake-out properties and dimensional stability to sand cores.
• Composite Materials: Employed as a matrix resin or modifier in fiber-reinforced plastics (FRP) to improve toughness and impact resistance.

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, viscosity, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each 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). Keep away from heat, sparks, and open flame. This product is compatible with strong acids and organic solvents but should be stored separately from strong oxidizing agents. Keep container tightly sealed when not in use to prevent moisture absorption and skin formation.
