Surface
Coated, very fine Calcium Carbonate Powder,
manufactured from selected high grade limestone.
It is characterised by its high whiteness and
consistent fine particle size. It is surface -
treated to make the particles completely
hydrophobic for ease of dispersion, improved
processing characteristics and minimal moisture
uptake.
