Pigment and filler surface treatment agent

Japan Shin-Etsu Silica Spherical Fine Particles

Silica spherical particles

Silica spherical particles with extremely small particle size, narrow particle size distribution, and highly hydrophobicized surface. Therefore, it is excellent in dispersibility, hydrophobicity, lubricity, and fluidity, and these properties can be imparted in the drying process by adding other powders. In addition, it can be used not only for inorganic series but also for organic series powder.
