Description

Phenol, Tetrapropylene-, Sulfurized, Carbonates, Calcium Salts, Overbased is a specialized, high-performance overbased calcium sulfonate complex. This compound is engineered to provide exceptional alkalinity reserve and detergent-dispersant properties, making it a critical component in advanced lubricant and fuel formulations. It is primarily utilized by formulators in the lubricant, grease, and fuel additive industries seeking to enhance product performance, neutralize acidic by-products, and extend equipment life under severe operating conditions.

Application

• As a high-alkalinity detergent and dispersant additive in marine diesel engine oils to neutralize acidic combustion products and control deposits.
• A key component in the formulation of high-performance industrial greases, providing rust inhibition and extreme pressure (EP) properties.
• Used in automotive engine oils (particularly for heavy-duty applications) to manage soot, sludge, and acid control.
• As an additive in metalworking fluids and industrial lubricants to improve stability and protect against corrosion.
• Employed in fuel additive packages to act as a detergent and combustion improver.
• Functions as a stabilizer and acid scavenger in various polymer and chemical processing applications.
