Description

Fatty Acids, C16-18 And C18-Unsatd., Dimerized is a high-purity, synthetic dimer acid derived from unsaturated C18 fatty acids. This specialized chemical is valued for its excellent thermal stability, flexibility, and adhesion properties, making it a critical intermediate for high-performance polymers. It is essential for manufacturers in the coatings, adhesives, and lubricant industries seeking to enhance product durability and performance.

Application

• Polyamide Resins: A key monomer for producing non-reactive, thermoplastic polyamide hot-melt adhesives with excellent flexibility and adhesion to various substrates.
• Corrosion Inhibitors: Used in formulating high-performance corrosion inhibitors and rust preventatives for industrial lubricants and metalworking fluids.
• Epoxy Curing Agents & Modifiers: Acts as a flexibilizer and toughening agent in epoxy resin systems, improving impact resistance and reducing brittleness.
• Synthetic Lubricants: Serves as a base fluid or additive in synthetic lubricants and greases, contributing to high thermal stability and low pour points.
• Alkyd Resins: Used in modified alkyd resins for coatings to improve drying time, flexibility, and chemical resistance.
• Printing Inks: Employed in resin formulations for printing inks to enhance gloss, adhesion, and rub resistance.
