Features
The uniformity of particle shape and dispersibility are excellent.
Because the Mohs hardness is as low as 3, the mechanical wear is less compared to silicate mineral.
Because the whiteness is high, it does not prevent color production and color adjustment can be performed easily.
Because the product is finished in fine mesh, there are very few coarse particles.
Very few fine powders are included, which minimizes increase in resin viscosity and allows it to be much compounded.
Because of calcium carbonate, this product is safer than silica.
This product is a patented item.
