Description

2-Ethylhexyl Phosphate (Mixture Of Mono And Diesters) 45% is a versatile organophosphorus acid ester blend, primarily valued for its excellent surface-active and metal-chelating properties. This product is crucial for industrial processes requiring effective wetting, emulsification, or corrosion inhibition. It is essential for manufacturers in sectors such as metalworking, polymer production, and specialty chemical formulation.

Application

• Metalworking Fluids & Lubricant Additives: Acts as an effective anti-wear agent, extreme pressure additive, and corrosion inhibitor in synthetic and semi-synthetic metalworking fluids.
• Polymerization & Plastic Additives: Serves as an acid catalyst, emulsifier, or stabilizer in the production of polymers and as an antistatic agent in plastic formulations.
• Extraction & Separation Processes: Utilized as a selective extractant for rare earth metals and other valuable ions in hydrometallurgical and solvent extraction applications.
• Surfactant & Emulsifier Intermediate: Functions as a key raw material for the synthesis of anionic surfactants and specialty emulsifiers for industrial and institutional cleaners.
• Corrosion Inhibitor Formulations: Incorporated into protective coatings, fuel additives, and industrial water treatment systems to prevent metal degradation.
• Textile & Leather Processing: Used as a wetting agent, penetrant, and softening auxiliary in textile finishing and leather tanning processes.
