A coarse ground natural calcium carbonate for use in putties, glazes and mild abrasive compounds. It is frequently blended with Atomite to achieve a wider distribution of particles which yields effective particle packing properties. 

A series of coarse ground calcium carbonate fillers used in polyolefins, carpet backing, caulks, sealants, and putties, and as mild abrasives in cleaners. These products offer a formulator a choice of fillers having low oil absorption, low resin demand, and average dry brightness. 

The following raw materials were used for the laboratory reproduction of Egyptian Blue coarse-grained quartz (quartz sand <250 jLm, Pilking-ton Brothers Ltd.) or fine-grained quartz (ground flint <53 JLm, Fulham Pottery Ltd.) calcium carbonate (<53 xm, Analar) malachite (<53 xm) and anhydrous sodium carbonate (<53 xm, Analar). 

Calcium carbonate fillers are either of ground limestone type or precipitated chalk type. They are inexpensive and have low oil-absorption, which allows considerable freedom in filler levels while keeping the viscosity under control. Relatively coarse particle size fillers ranging from 30 to 100 mesh are used to incorporate high loadings. 

Calcium Carbonates - Calcium carbonate fillers are available in a wide range of particle sizes and can be obtained as wet or dry ground limestone, chalks, or precipitated carbonates. The carbonates with a coarse particle size reinforce slightly and increase viscosity slightly. However, they are used to adjust rheology and lower the cost of a compound. The coarse and fine carbonates are generally used together.
