Super Overbased Synthetic Calcium Sulfonate

Product Introduction：

Super overbased Synthetic Calcium Sulfonate is manufactured with long-chain linear alkylbenzene sulfonic acid as the main raw material with the process of neutralization and alkalization reaction. The product has excellent base reserve, good oil solubility and strong acid neutralization properties, and it is able to immediately neutralize organic acid and inorganic acid in the oil, as well as provide with excellent high-temperature detergency and thermal stability properties. It is a preferred additive for over-based marine cylinder oil applications.
