Description

Fatty Acids, Tall-Oil, Maleated CAS NO 68139-89-9 is a chemically modified derivative of tall oil fatty acids, where maleic anhydride is reacted to introduce reactive carboxyl functionality. This modification significantly enhances its utility as a versatile chemical intermediate and performance additive. It is primarily sought after by manufacturers in the polymer, coatings, and lubricant industries seeking to improve product adhesion, cross-linking density, and rheological properties.

Application

• As a reactive diluent and cross-linking agent in alkyd resins and other coating formulations.
• Key intermediate for the synthesis of polyamide resins and corrosion inhibitors.
• Modifier for epoxy systems to enhance flexibility and adhesion.
• Additive in lubricating greases and metalworking fluids to improve film strength and anti-wear properties.
• Raw material for producing surfactants and emulsifiers with specific performance characteristics.
• Component in adhesive and sealant formulations to boost tack and cohesion.
