Description

Fatty Acids, C18-Unsatd., Dimers, Reaction Products With Polyethylenepolyamines is a polymeric amine derivative of dimerized unsaturated C18 fatty acids, primarily oleic and linoleic acids. This specialized chemical is valued for its unique combination of hydrophobic fatty acid chains and reactive amine functionalities, making it an effective intermediate and performance additive. It is primarily sought by manufacturers in the coatings, adhesives, and lubricant industries seeking to enhance product properties such as adhesion, corrosion resistance, and surface activity.

Application

• As a curing agent or hardener in epoxy resin systems for coatings and composites.
• As a key intermediate in the synthesis of polyamide resins for printing inks, adhesives, and hot-melt applications.
• As a corrosion inhibitor and dispersant additive in industrial lubricants and metalworking fluids.
• As a surface-active agent and emulsifier in specialty chemical formulations.
• As a building block for cationic surfactants and asphalt emulsifiers.
• In the production of water-based coatings to improve film formation and substrate wetting.
