Description

Calcium Bis(Tetracosylbenzenesulphonate) is a high-molecular-weight organometallic salt derived from a long-chain alkylbenzenesulphonic acid. This compound is valued for its excellent surface-active and hydrophobic properties, making it a key functional additive in specialized industrial formulations. It is primarily utilized in sectors requiring advanced lubrication, corrosion inhibition, and material modification, such as high-performance greases, polymer processing, and metalworking fluids.

Application

• As a high-performance thickener and extreme pressure (EP) additive in complex calcium sulfonate greases.
• As a hydrophobic agent and corrosion inhibitor in protective coatings and rust preventatives.
• As a processing aid and internal lubricant in the manufacture of plastics and polymers.
• As a key component in metalworking fluids and drawing compounds for enhanced lubrication.
• As a surfactant and emulsifier for specialized industrial cleaning and degreasing formulations.
• As an additive in fuel and lubricant packages to improve detergency and stability.

Quality Control

Our production of Calcium Bis(Tetracosylbenzenesulphonate) adheres to stringent quality management protocols. Each batch is analyzed to ensure consistent chemical composition, purity, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as calcium content, sulfonate content, moisture, and viscosity are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture which may affect product quality.
