TBN for Grease – Overbased Calcium Sulfonate Complex Precursor

High-Performance Thickener Base for Extreme Pressure, Water-Resistant Grease Formulations

Description:
This product is a high-performance overbased calcium sulfonate precursor, specially formulated for the manufacture of premium compound calcium sulfonate greases. Produced using a combination of advanced technologies from the USA and Canada, along with proprietary local expertise, this thickener base offers exceptional anti-wear, extreme pressure (EP), and corrosion resistance properties.

The product appears as a dark brown, highly viscous liquid and is engineered to deliver outstanding thermal stability, oxidation resistance, and water resistance, including effective protection against moisture and seawater exposure. With a dropping point above 340°C, it ensures excellent performance in high-temperature applications and under heavy mechanical loads. It has demonstrated the ability to replace imported equivalents, and currently supports over 50% of the domestic market in China.

Key Benefits:

• Dropping point > 340°C – excellent high-temperature stability

• Strong EP and anti-wear performance – resists surface damage under high load

• Outstanding water resistance – resists washout from fresh and seawater exposure

• Superior shear and colloid stability – maintains structure under mechanical stress

• Excellent acid-base resistance – provides long-lasting protection in harsh environments

• Corrosion and rust protection – ideal for long-service industrial and marine applications

• Proven reliability – has replaced imported products for over a decade

Applications:

• Production of compound calcium sulfonate greases

• Suitable for industrial, marine, automotive, and heavy-duty applications
