Description

Calcium Petronate 25H is a high-performance calcium sulfonate additive, identified by CAS NO 73667-04-6. This compound is valued for its exceptional detergency and neutralizing properties, which are critical for maintaining equipment cleanliness and longevity in demanding environments. It is primarily required by formulators in the lubricant and grease industries seeking to enhance product performance and stability.

Application

• As a primary detergent and neutralizer in marine diesel cylinder oils and other high-alkalinity lubricants.
• A key component in the formulation of high-performance calcium sulfonate complex greases, providing superior mechanical stability and corrosion resistance.
• Used in industrial gear oils and hydraulic fluids to control deposit formation and neutralize acidic by-products of oxidation.
• Acts as a rust and corrosion inhibitor in various metalworking fluids and protective coatings.
• Employed as an additive in automotive engine oils to manage soot-induced viscosity increase and wear.
• Serves as an emulsifier and stabilizer in certain specialty industrial formulations.
