Description

Fatty Acids, Tall-Oil, Me Esters CAS NO 74499-22-2 are a versatile class of methyl esters derived from tall oil fatty acids, offering excellent solvency and reactivity. This product is valued for its renewable origin and its role as a key intermediate and functional fluid in various industrial formulations. It is essential for manufacturers in the lubricants, metalworking fluids, biodiesel, and polymer industries seeking sustainable and high-performance raw materials.

Application

• Bio-lubricants & Metalworking Fluids: Acts as a base stock or additive, providing good lubricity, low-temperature performance, and biodegradability.
• Biodiesel & Fuel Additives: Serves as a feedstock for biodiesel production or as a component in fuel additives to improve combustion and reduce emissions.
• Polymer & Resin Modification: Used as a plasticizer or reactive diluent in alkyd resins, epoxy systems, and other polymers to enhance flexibility and processing.
• Surfactants & Emulsifiers: Functions as a hydrophobic intermediate in the synthesis of non-ionic surfactants for cleaning and agrochemical formulations.
• Corrosion Inhibitors: Employed in protective coatings and industrial fluids to form a protective film on metal surfaces.
• Solvents & Carrier Fluids: Utilized as an eco-friendly solvent in inks, coatings, and degreasers due to its effective solvency power.
