Description

9-Octadecenoic Acid, Calcium Salt, Overbased is a specialized metallic soap and overbased calcium carboxylate. This compound is valued for its high total base number (TBN) and its ability to function as a powerful acid neutralizer and detergent in complex formulations. It is primarily utilized in the lubricant and grease industries, where its overbased nature provides superior performance in neutralizing acidic by-products and preventing corrosion.

Application

• As a high-TBN detergent and acid neutralizer in engine oils and marine lubricants.
• As a key performance additive in the formulation of industrial greases to enhance stability and load-bearing capacity.
• As a component in metalworking fluids to provide alkalinity reserve and corrosion protection.
• As a stabilizer and acid scavenger in synthetic lubricants and functional fluids.
• In the production of polymer stabilizers and plastic additives.
• As a chemical intermediate for the synthesis of other specialty metal carboxylates.
