Nano titanium dioxide transparent dispersion is a water-based transparent dispersion of nano titanium dioxide that uses internationally advanced dispersion technology to disperse nano titanium dioxide powder (5-30nm) in an aqueous medium, forming a highly dispersed, uniform, and stable nano titanium dioxide dispersion. Nano titanium dioxide transparent dispersion has the characteristics of nano powder, while nano titanium dioxide transparent dispersion has higher activity and is easy to add. The nano titanium dioxide dispersion greatly plays the role of nanomaterials.
