Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Azelaic Acid, Ethylenediamine, Hexamethylenediamine And Tall-Oil Fatty Acids CAS NO 68526-13-6 is a high-performance polyamide resin intermediate derived from dimerized and polymerized unsaturated C18 fatty acids. This specialized chemical offers exceptional thermal stability, adhesion, and flexibility, making it a critical component for formulating durable industrial products. It is primarily sought by manufacturers in the coatings, adhesives, and ink industries seeking to enhance the performance characteristics of their final materials.

Application

• Reactive Modifier for Polyamide Resins: Used to impart flexibility, improved adhesion, and chemical resistance in hot-melt and solvent-based polyamide adhesives.
• Corrosion-Resistant Coatings: Serves as a key building block in epoxy and alkyd coating systems for marine, industrial, and protective applications.
• Printing Inks: Enhances pigment wetting, gloss, and substrate adhesion in flexographic and gravure inks.
• Industrial Adhesives & Sealants: Improves bond strength and durability in construction, automotive, and packaging adhesives.
• Foundry & Casting Resins: Acts as a core binder or modifier in sand-casting and shell molding processes.
• Can & Coil Coatings: Provides essential film-forming properties and resistance in coatings for metal packaging and architectural panels.
