Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Diethylenetriamine And Ethylenediamine is a high-performance polyamide resin intermediate derived from unsaturated C18 fatty acid dimers. This specialized chemical is engineered to provide enhanced thermal stability, adhesion, and flexibility in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and ink industries seeking to improve the performance characteristics of their final products.

Application

• Corrosion-Resistant Coatings: Used as a curing agent and flexibilizer in epoxy-based coatings for marine, industrial, and protective applications.
• High-Performance Inks: Serves as a resin modifier in flexographic and gravure inks to enhance adhesion to non-porous substrates and film flexibility.
• Industrial Adhesives & Sealants: Acts as a reactive building block in polyamide hot-melt and solvent-based adhesives, improving bond strength and impact resistance.
• Foundry Resins: Employed in binder systems for sand cores and molds, contributing to excellent shake-out properties and casting finish.
• Composite Materials: Functions as a toughening agent in fiber-reinforced polymer composites for automotive and construction sectors.
• Overprint Varnishes: Modifies the properties of varnishes to increase scuff resistance and gloss on packaging materials.
