Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Ethylenediamine And 1-Piperazineethanamine is a high-performance polyamide resin derived from dimerized unsaturated C18 fatty acids and a blend of polyamines. This specialized chemical functions as a versatile rheology modifier and thixotropic agent, providing critical structural and performance benefits in formulated products. It is essential for manufacturers in the coatings, adhesives, sealants, and inks industries seeking to enhance viscosity control, sag resistance, and application properties.

Application

• Coatings & Paints: Acts as a primary thixotropic agent and anti-settling additive in solvent-based and high-solids industrial coatings, marine paints, and protective coatings.
• Adhesives & Sealants: Used as a rheology modifier to impart non-drip characteristics, improve gap-filling properties, and control slump in construction adhesives and mastics.
• Printing Inks: Serves as a gelling agent and viscosity stabilizer in gravure, flexographic, and specialty inks to ensure sharp print quality and prevent pigment settling.
• Lubricating Greases: Functions as a thickener and structure-forming agent in complex soap-based greases, contributing to thermal stability and water resistance.
• Foundry & Casting: Employed as a binder component in core and mold-making sands to provide green strength and improve casting finish.
• Polymer Modification: Utilized as a curing agent or cross-linking modifier for epoxy resins and other polymers to tailor flexibility and chemical resistance.
