AEROXIDE® STX 801
AEROXIDE® STX 801 is a hydrophobized fumed silicon-titanium mixed oxide with a titanium dioxide core and a silica shell. It combines the triboelectrical charge attributes of titanium dioxide with the surface properties of a silica. Its high hydrophobicity is imparted by trimethylsilyl-groups which are firmly anchored to the silica surface.
Applications Toner Properties Quick charge-up resulting in a medium negative electrostatic charge Excellent electrostatic charge stability under different enviromental conditions (L/L as well as H/H) Good charge modulator due to the core semi-conductivity (electrical resistivity 108 Ω·cm) High level of hydrophobicity High purity and very low moisture content High UV-B-absorbitivity
