Functional mineral fillers

Talc micropowder is made of sliding stones through cleaning, screening, grinding, grading and other processes. It is a white powder, which has excellent physical and chemical properties such as lubricity, extinction, fire resistance, insulation, high melting point, chemical inactivity and strong adsorption. Kmeris Mineral Products is a leading producer of talcum powder in China. Our Superfine Talc Powder, Talc power F020 F017 F022 F018 F028 F023 F019 are widely used by famous international architectural paints factories world widely.    

Talc powder is an industrial mineral that has been used as a pigment and filler in paints & coating, paper making, rubber, modified plastic, ceramic, adhesive and other  industries. It is mainly composed of hydrous magnesium silicate, which is processed into powder after selection, washing and crushing. Kmeris Mineral Products is a leading producer of talcum powder in China. Our Superfine Talc Powder, Talc power F020 F017 F022 F018 F028 F023 F019 are widely used by famous international architectural paints factories world widely.

Fused silica powder is a kind of powder which is made of high-quality natural quartz and processed by a unique processing technology. After high temperature treatment, the molecular structure of natural quartz changed from ordered arrangement to disordered arrangement. Its color is white and its purity is high. At the same time, it has the following characteristics: very low linear expansion coefficient; It has good electromagnetic radiation performance, chemical corrosion resistance and stable chemical characteristics; Has reasonable, orderly and controllable particle size distribution.

Fused silica powder is an amorphous silicon dioxide powder material made by melting natural quartz into amorphous quartz through electric melting, and then through crushing, sorting, grinding, grading and other processes. Fused Silicon Powder for paint and coating has good stability and has been playing a major role in coating fillers. For example, the addition of silicon powder in high temperature resistant coatings (ceramic coatings) can not only play a role of filling but also improve the hardness of the paint film, enhance the paint resistance, scrub resistance, corrosion resistance, and meantime have the performance of assisting extinction.

Fused silica powder is made of natural SiO2 or molten amorphous SiO2 after high-temperature melting and cooling in natural quartz through crushing, ball milling (or vibration and jet milling), flotation, acid cleaning and high-purity water treatment. Fused Silicon Powder for paint and coating has good stability and has been playing a major role in coating fillers. For example, the addition of silicon powder in high temperature resistant coatings (ceramic coatings) can not only play a role of filling but also improve the hardness of the paint film, enhance the paint resistance, scrub resistance, corrosion resistance, and meantime have the performance of assisting extinction.

Precipitated barium sulphate features for high resistance to outdoor exposure and other chemicals, extremely fine particle size and a narrow particle size distribution D50≤ 4.5 µm, ideally-suited for high gloss applications. Our Precipitated barium sulphate is widely used by paints, powder coatings, ink and plastics.  

Precipitated barium sulfate is an amorphous white powder produced by chemical precipitation method, and its physical properties, purity and whiteness are better than those of superfine natural barium sulfate, which is non-toxic and tasteless.  

The appearance of KNR-508 was the white fluffy powder, which was coated with hydrated alumina or/and hydrated zirconia, and the main chemical constituents are titanium dioxide. The paint film not only had good light resistance, but also had angle-dependent optical effect, which made from KNR-508 and aluminium paint and other materials.

This white powder pigment, primarily composed of titanium dioxide, stands as a testament to inertness, non-toxicity, and remarkable stability in chemical properties. This product was the white fluffy powder, which was coated with hydrated silica and alumina or/and organic agents such as stearic acid, triethoxyoctyl silica, polydimethyl silicone oil, and the main chemical constituents are titanium dioxide. The products made from KNR-308 as raw material or auxiliary material had excellent light resistance.
