Development History of Domestic Hyperdispersants

●In 1991, introductory reports on foreign hyperdispersants appeared in domestic literature.

●In 1992, East China University of Science and Technology engaged in the National Natural Science Foundation project "Study on the Dispersion Stability of Ultrafine Powders in Non-aqueous Solvents".

●In 1993, East China University of Science and Technology and SICPA cooperated in the synthesis and application research of hyperdispersants for inks.

●In 1994, the pilot products of WL series hyperdispersants passed the expert appraisal organized by Shanghai Science and Technology Commission and were applied in Shanghai Ink Factory and other units.

●In 1994, East China University of Science and Technology's research on hyperdispersants was funded by the Shanghai Science and Technology Commission's International Cooperation Program and the Ministry of Chemical Industry's Science and Technology Development Program.

●In 1995, WL series hyperdispersants were Rated as a national key new product.

●In 1996, the first national patent for hyperdispersant was applied (patent number 96116371.2).

●In 1997, the hyperdispersant project was funded by the Shanghai Science and Technology Commission's Youth Science and Technology Rising Star Program, and the pilot product was officially launched on the market, which immediately attracted close attention from foreign companies.

●In 1998, foreign companies negotiated with East China University of Science and Technology on the cooperation plan for the hyperdispersant project in view of their market interests in China and related regions.

●At the end of 1999, Shanghai Sanzheng Polymer Material Co., Ltd. was officially established, specializing in the research, development, production, sales of hyperdispersants and related technical services and technical consulting services.

●Since 2000, Sanzheng Company has continued to increase its investment in scientific research. With the support of Shanghai Small and Medium Enterprises Technology Innovation Fund (seed funds), the National Torch Program and the National Innovation Fund, it has developed new CH series hyperdispersant products, achieved multiple product upgrades, and applied for relevant patents.

●Shanghai Sanzheng Polymer Material Co., Ltd. has been deeply engaged in the field of hyperdispersants for more than 20 years. Its current series of products are used in industries such as inks, paints, color pastes, masterbatches, ceramics, electronic pastes, nanopowders, functional fillers, etc., helping customers overcome many technical problems related to powder surface treatment and dispersion.
