High Speed Dispersion of Titanium Dioxide

Global Spec logo  

From Silverson Machines, Inc.

Titanium dioxide (TiO2) is chemically inert and has exceptional opacity and whiteness. These properties have led to its widespread use in many industries.

Titanium dioxide is most commonly supplied in powder form but may also be pre-dispersed in oil or aqueous systems. The diversity of applications leads to many different methods of processing, however process requirements are basically the same:

* TiO2 is usually supplied in powdered/pre-micronized form and particle size reduction (grinding) is not applicable in most cases.
* To maximize opacity and gloss properties,TiO2 must be fully dispersed and evenly distributed throughout the product
* Dust/solvent emissions must be minimized

The high speed, high shear operation of a Silverson mixer provides the solution to these problems. The rotor/stator workhead rapidly disperses the TiO2 particles into the surrounding liquid, leading to a more uniform product and shorter processing times.
