Description

Calcium Bis(Butylnaphthalenesulphonate) is a specialized organometallic salt widely utilized as a high-performance surfactant and emulsifier in industrial formulations. Its primary value lies in its excellent surface-active properties, which enhance the stability and performance of complex chemical systems. This product is essential for manufacturers in the lubricant, fuel additive, and specialty chemical industries seeking to improve product efficacy and process reliability.

Application

• Lubricant and Grease Additive: Acts as a detergent and dispersant to prevent sludge formation and neutralize acidic by-products in engine oils and industrial greases.
• Fuel Additive: Used in diesel and gasoline formulations to clean fuel injectors, prevent corrosion, and improve combustion efficiency.
• Industrial Emulsifier: Serves as a key component in the production of oil-in-water (O/W) emulsions for metalworking fluids, agricultural chemicals, and textile processing aids.
• Rust and Corrosion Inhibitor: Provides protective films on metal surfaces in cooling systems, hydraulic fluids, and protective coatings.
• Polymerization Aid: Functions as an emulsifier and stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.
• Concrete Admixture: Employed as an air-entraining agent or plasticizer to improve the workability and durability of concrete mixes.
