Description

Bis(4-Dodecylbenzenesulfonic Acid)Calcium Salt is a high-purity, organometallic sulfonate salt widely used as a versatile performance additive. This compound is valued for its excellent surfactant properties, thermal stability, and compatibility with various polymer systems. It serves as a critical component in the formulation of lubricants, plastics, and specialty coatings for demanding industrial applications.

Application

• Lubricant & Grease Additive: Acts as a high-performance detergent and dispersant in engine oils and industrial greases to prevent sludge and deposit formation.
• Polymer & Plastic Additive: Functions as an internal lubricant, antistatic agent, and processing aid in polyolefins (e.g., PP, PE) and engineering plastics.
• Coating & Ink Industry: Used as a wetting and dispersing agent to improve pigment compatibility and stability in solvent-based and high-solid coatings.
• Metalworking Fluids: Enhances the emulsifying and anti-corrosion properties of cutting oils and coolants.
• Fuel & Oil Detergents: Employed in fuel additive packages to keep intake systems clean and improve combustion efficiency.
• Specialty Surfactant: Serves as a key intermediate for synthesizing other sulfonate-based surfactants and emulsifiers.
