Pigments and fillers
Surfactant free dispersions
Colloidal silica is used for the
dispersion of many inorganic pigments and fillers. The small charged colloidal silica particles surround the filler or pigment particles and act as a spacer to keep the particles separated. This greatly increases the light scattering efficiency.
The benefits are:
Good dispersing power and pigment wetting
Surfactant free pigment paste
Enhanced opacity
Reduced foam formation (in paste and coating)
Improved chemical resistance in coatings
Possibilities for improving process efficiency
Good pigment paste stability and easier to re-disperse paste if settled
Easy to use and not shear sensitive
