Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine, Hexamethylenediamine, Isophthalic Acid And 2-Methylpropanoic Acid is a high-performance polyamide resin intermediate, synthesized from dimerized unsaturated C18 fatty acids. This complex polymer offers exceptional thermal stability, chemical resistance, and adhesion properties, making it a critical component for formulating durable industrial products. It is primarily sought after by manufacturers in the coatings, adhesives, and engineering plastics industries seeking to enhance the performance and longevity of their materials.

Application

• Hot-Melt Adhesives (HMA): A key building block for formulating high-performance polyamide hot-melt adhesives with excellent flexibility, heat resistance, and adhesion to diverse substrates.
• Industrial & Protective Coatings: Used in solvent-based and powder coatings to improve film hardness, chemical resistance, and durability for automotive, marine, and industrial maintenance applications.
• Inks & Toners: Serves as a resin component in printing inks and electrophotographic toners, contributing to gloss, rub resistance, and substrate adhesion.
• Engineering Thermoplastics: Acts as a modifier or compatibilizer in nylon and other polyamide blends to enhance impact strength and processing characteristics.
• Corrosion Inhibitors: Utilized in the formulation of protective primers and anti-corrosive coatings for metal surfaces.
• Flexible Packaging Laminates: Employed in adhesives for multi-layer food and industrial packaging films requiring strong bonds and resistance to flexing.
