Description

Phosphoric Acid Bis(2-Methylpropyl)=Potassium Ester Salt is a specialized organophosphorus compound, specifically a potassium salt of a diisobutyl phosphate ester. This product is valued for its role as an effective anionic surfactant and corrosion inhibitor in advanced industrial formulations. It is primarily sought by manufacturers in the lubricant, metalworking fluid, and specialty chemical sectors who require high-performance additives for stability and surface activity.

Application

• As a key corrosion inhibitor and anti-wear additive in synthetic and semi-synthetic metalworking fluids and hydraulic oils.
• Functioning as an anionic surfactant and emulsifier in industrial cleaning and degreasing formulations.
• Utilized as a stabilizing agent and acidity regulator in specialty lubricant and grease production.
• Employed in the formulation of anti-rust treatments and coatings for metal surfaces.
• As a component in flame-retardant plasticizer systems for certain polymer applications.
• Potential use as a specialty intermediate in the synthesis of other organophosphate compounds.
