Huber’s Calcium Carbonate TiO2 Extender Solution

Huber Engineered Materials has a high-peforming TiO2 spacer for you to consider:  Optifil® JSU calcium carbonate.  Optifil JSU is an ultrafine ground calcium carbonate product grade produced from a specialty ore deposit.  It has a median particle size of 1.0 and its soft ore body results in a more rounded shape (see the electron micrograph at right), which promotes dispersion and less crowding.  The milling process also results in roughly 40% of the particles by weight being less than 1 micron, an ideal size for spacing TiO2.  It is for use in interior applications.  Order your sample today!
