Function features of Sulfonated tannin CAS:97660-15-6:

Viseosity reducers for drilling fluid - sulfonated tannin (SMT) is made from tannin extract andtannie acid by sulfonation and chemical modification, The product is free-flowing brown powderand easily soluble in water, with strong water absorption.

SMT is an excellent diluent or viscosity reducer in all types of water-based drilling fluidsystems. SMT can effectively reduce the viscosity and shear of drilling fluid. It can also maintain acertain viseosity reduetion ability in salt water drilling fluid and saturated salt water drilling fluid.and the resistance to Ca2+ pollution can reach more than 1000mg/L, Under the high-temperaturecondition of 180~200C, it can improve the high-temperature stability of the drilling fluid andcontrol the rheological property of the drilling fluid at high temperature.

SMT can be well compatible with other commonly used drilling fluid additives to achievemultiple effects.

SMT is also commonly used as a high-temperature retarder and dispersant for cement slurry.
