Description: Product conversion rate over 95%, brightness 96, particle size controllable from 325 mesh to 5000 mesh.

Fused quartz powder contains about 99.5% silicon, with a conversion rate of over 95%, a whiteness of above 98, and a crystal phase of the tetragonal system. It exhibits excellent insulation, anti-settling, corrosion resistance, heat shock resistance, high-temperature resistance, good wear resistance, good fluidity, low conductivity, and high impact and compressive strength. Therefore, it performs well in high-end exterior coatings and paints.

It possesses excellent optical properties. The refractive index of feldspar quartz is reduced from quartz's 1.55 to 1.48, making it closer to the refractive index of PE, PP, and some resins. The mixed resin appears transparent, not obscuring the inherent color of the pigment. However, using other fillers would lighten and distort the pigment's color.

High reflectivity. The octahedral structure of feldspar aids in light reflection, making it a substitute for glass microbead reflective paint. It enhances both the anti-slip properties and the reflectivity of the paint.

High brightness, low density, lustrous color. The whiteness of square quartz reaches 96%, which can replace part of titanium dioxide in paints and lacquers, reducing the cost of the formula. It is suitable for automotive undercoats and as a filler for various paints and lacquers.

Corrosion-resistant, scratch and wear-resistant.

Non-polluted with organic substances, extremely low metal content. Enhances the coating's UV resistance and boasts excellent insulating properties, suitable for encapsulation and filling in electronic products.
