Modified Tannin SMT Desco CF CAS #: 20-568-87 "
Modified Tannin SMT Desco CF (CAS 20-568-87) from Weifang Longstar Chemical Inc. is a sulfonated gallnut tannin presented as a free-flowing brown powder. It is engineered for industrial applications where strong water absorption and solubility are critical. The product is specifically formulated to perform as a viscosity reducer in water-based mud systems, maintaining effectiveness even in saltwater and saturated saltwater environments. Its chemical modification allows it to withstand calcium pollution up to 1000 mg/L, making it suitable for demanding drilling conditions.
The material is derived from gallnut through sulfonation and further chemical processing, resulting in a product with consistent performance at elevated temperatures. In drilling fluid applications, it reduces viscosity and shear force while improving high-temperature stability up to 180-200°C. It also serves as a high-temperature retarder and dispersive drag reducer for cementing slurries, with good compatibility with other mud additives. The powder meets industrial-grade specifications typical for specialty tannin derivatives used in water treatment, mining, and leather processing.
Industrial buyers sourcing this product benefit from its versatility in water treatment as a flocculant, in mining as an ore depressant, and in leather processing for tannin-based applications. The product is packaged in 25kg paper bags with a minimum order of 1 metric ton, standard for bulk chemical exports. Buyers in oilfield services, mineral processing, and chemical manufacturing rely on its consistent performance in high-temperature and high-salinity environments, where conventional additives may fail.
