Microna™ 3 is a dry, fine, double classified natural calcium carbonate filler/extender specifically designed for use in all types of coatings and paints. It provides consistent high fineness of grind readings and good gloss development. Microna™ 3 is used at high levels in putties, caulks, and sealants because of its nominal oil absorption.

Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs of 3. Since ground calcium carbonate is a naturally mined material, impurities exist in all ore bodies. Almost all contain some dolomite (CaMg(CO 3) 2) with a Mohs of 4, while others contain mica (Mohs 3) or graphite (Mohs 1-2).
