In paint, coatings, resistance exposure, high temperature, does not change color under ultraviolet light, long-term to maintain the original luster and color, there is a good acid corrosion resistance, and water resistance, stain resistance, Strong aging properties, wear resistance, steam and chemical stability, and more fire-retardant properties. Formula Mg3 [Si4O10] (OH) 2 characteristics: a hydrous silicate minerals having a layered structure. The chemical composition of magnesium oxide (MgO) 31.88%, (silica) SiO2 63.37%, H2O 4.75%, often containing small amounts of Fe, Al and other elements. Scope: used in rubber, plastics, paints, glass, steel and other chemical industries as a reinforcing filler modified.
