Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Diethylenetriamine, Ethylenediamine, Sebacic Acid And Tall-Oil Fatty Acids is a high-performance polyamide resin intermediate, synthesized from renewable tall oil fatty acids. This specialized polymer offers excellent adhesion, flexibility, and chemical resistance, making it a critical component for formulating durable industrial coatings and adhesives. It is essential for manufacturers in the coatings, printing inks, and construction chemical sectors seeking to enhance product performance and sustainability.

Application

• Corrosion-Resistant Industrial Coatings: Used as a reactive diluent and modifier in epoxy and alkyd-based coatings for metal protection.
• High-Performance Printing Inks: Imparts gloss, adhesion, and rub resistance in flexographic and gravure inks for packaging.
• Construction Adhesives & Sealants: Acts as a flexibilizer and tackifier in polyamide-cured epoxy adhesives and polyurethane sealants.
• Marine & Protective Coatings: Enhances water resistance and durability in primers and topcoats for ships and offshore structures.
• Can & Coil Coatings: Provides formulation stability and adhesion for coatings applied to metal containers and coils.
• Automotive Underbody Coatings: Contributes to stone-chip resistance and corrosion protection.
