Coated Calcium Carbonate powder 8 +/- 2µ

BL08S is a high whiteness ground coated calcium carbonate 8 micron derived from pure Vietnam white marble. It is milled and classified to below 08 microns and 1% coated with stearic acid. It is surface – treated to make the particles completely hydrophobic for ease of dispersion, improved processing characteristics and minimal moisture-uptake.

Bao Lai offers a diverse set of ground calcium carbonate powder from Vietnam white marble suited for a wide range of applications including plastics, paints & coatings, construction materials, adhesives, sealants, food & pharmaceutical products, paper & ink, and lawn care.
