Our range of Precipitated Barium Sulfate HTS-H is a chemically synthesized barium sulfate product (BLANC FIXE) refined through special manufacturing processes with highly pure barium salt and sodium sulfate as its raw materials. Its grain sizes are under strict control in the course of reactions and synthesis and content of impurities is minimized. It features low specific weight, gentle and stable nature, narrow distribution of grain sizes, extremely good light fastness, weathering resistance and other outstanding chemical properties.
The uniquely spherical or near spherical ( D50< 1.0um ) ultra-fine barium sulfate crystal grains of HOTEN SUPER FINE HTS are provided with big specific surface areas, thereby effective increasing or magnifying the light reflecting area in coating. Therefore it is widely applied in the formula system of high-gloss products.
By using its own ( 15g / 100g ) low oil absorption, HOTEN SUPER FINE HTS may be fully mixed with other resin components, i.e. the same equivalent weight of resin may carry more HOTEN SUPER FINE HTS. In particular, it gives a vivid color, repeatable tint and perfect surface gloss when compounded up with pigment in a formula. Its low consumption of base material guarantees the high rheological property in system and good mechanical property of finished products.
