Compared to other materials commonly used in paints, coatings-why choose us
The commonly additivesused in Paints and coatings have wollastonite powder, silicon dry soil, quartz powder, mica powder, talc powder , glass beads, kaolin, silica, precipitated barium sulfate, heavy carbonate, light calcium,etc.The majority of these materials through the crushed into powder, part of them made by chemical precipitation, most of them are amorphous structure and difficult to disperse in paints and coatings. The product have bad thixotropy and easy to precipitate, easy caking , usually, by added expensively modified bentonite to adjust the thixotropy of the paint, on order to prevent pigment sinking and caking when stored.
Our silica powder is the unique minerals in China with its high purity. The ore is soil-like, particles is spherical. Our silica powder have the following characteristics: (1) Easily dispersed in paints and coatings and can significantly reduce the amount of modified bentonite with its good thixotropy, suspension and anti-settling properties. (2) As to the construction performance of paints and coatings, it is easily hanging flow if use precipitated barium carbonate, but our silica powder have no this problem (3) Can significantly improve the coating hardness, wear resistance, weather resistance, anti-acid and anti-alkali corrosion as well as other physical and chemical properties (4) Our silica powder can effectively reduce the overall costs for its lower price while improve the performance of paints and coatings.

Features of our silica powder
(1)Our silica powder adopted the domestic unique high-quality quartz powder, gained by wet processing. Microcosmic particles are spherical, SiO2 content ≥ *9.*0%, does not contain any heavy metals and radioactive elements, its excellent performance completely different from the ordinary micro silica powder.
(2) Ideal for high-end filler of paints and coatings for properties of low impurity, high fineness ,high hardness, strong adhesion, high resistivity, good suspension performance, acidproof and alkaliproof.
(3)Water absorption much lower than general clay minerals, such as calcium carbonate, kaolin, talc, etc.Oil absorption rate and other index have more competitive advantage.
(4)Due to the unique particles microscopic morphology, our powder have good compatibility in the resin or sol system and have a low viscosity, thus making the system has a good dispersibility, suspension and good anti-settling properties, which superior to the traditional barium sulfate powder. For its good stability and higher fill ratio, our powder can replace the precipitated barium sulfate.
(5)Due to the stability of its chemical composition and molecular structure, our powder can significantly improve the corrosion resistance, abrasion resistance, weather resistance, insulating properties, resistance to high temperature of paints and coatings.
(6)More cost-effective compared with other fillers, improving performance of paints and coatings while effectively reducing the cost.
(7)Because of our powder's ingredients similar with fumed silica, it can be used as filling reinforcing material in polymers, like rubber, resin, paint, paint, and not full of ester, etc.
