Detergency SDL15B

Product introduction

Detergency SDL15B is one of the series of lubricant additives developed by us through technical cooperation with Sinopec Research Institute of Petroleum Processing. It’s made from dodecylphenol by means of vulcanization, neutralization and high-base reaction. This product is a kind of widely used lubricant additive of comprehensive performance, boasts extremely good acid neutralization capacity and high-temperature detergency, excellent oxidation resistance and corrosion control as well as good emulsion resistance and oil solubility. It’s compatible with sulphonates, alkenyl succinimide, ZDDP and other additives. It has prominent effect in reducing top-piston ring carbon and is widely used to prepare middle and high-grade ICE oils.
