Description

Calcium Bis(Dinonylnaphthalenesulphonate) is a high-performance, oil-soluble calcium sulfonate complex widely recognized for its exceptional properties as a detergent, dispersant, and rust inhibitor. Its primary value lies in its ability to neutralize acidic by-products and prevent sludge formation in demanding industrial environments, thereby extending equipment life and operational efficiency. This product is essential for formulators and manufacturers in the lubricant, grease, and fuel additive industries who require reliable metal-working and corrosion protection agents.

Application

• Primary component in the formulation of overbased calcium sulfonate complex greases, providing extreme pressure (EP) and anti-wear properties.
• Key detergent and dispersant additive in marine diesel engine oils and other high-performance lubricants to control deposits and neutralize acids.
• Effective rust and corrosion inhibitor in industrial lubricants, metalworking fluids, and protective coatings.
• Used as an emulsifier and stabilizer in various oil-based systems and specialty chemical preparations.
• Additive in fuel treatments to prevent injector fouling and combustion chamber deposits.
• Functional intermediate in the synthesis of other specialty sulfonate derivatives for niche industrial applications.

Quality Control

Our Calcium Bis(Dinonylnaphthalenesulphonate) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of key parameters such as Total Base Number (TBN), calcium content, viscosity, and sulfated ash. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and incompatible materials. For long-term storage, ensure containers are kept tightly sealed to prevent moisture absorption and contamination.
