Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine, Pentaerythritol, Phthalic Anhydride And Tall-Oil Fatty Acids CAS NO 68604-95-5 is a high-performance, synthetic polymer resin derived from modified tall oil fatty acids. This versatile compound is engineered to provide excellent adhesion, flexibility, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and ink industries for its ability to enhance product durability and performance.

Application

• Industrial Coatings Binder: Used as a primary resin or modifying agent in high-performance alkyd paints, marine coatings, and corrosion-resistant primers.
• Adhesive Formulations: Serves as a key polymeric component in structural adhesives, laminating adhesives, and pressure-sensitive adhesives (PSAs) to improve bond strength and flexibility.
• Printing Inks: Imparts excellent gloss, adhesion, and rub resistance in solvent-based and overprint varnish formulations.
• Sealants and Caulks: Acts as a plasticizing and film-forming agent, enhancing elasticity and long-term weatherability.
• Polymer Modification: Utilized as a reactive intermediate or crosslinker to modify the properties of other polymers, improving toughness and chemical resistance.
