99% purity calcium carbonate

1.Calcium carbonate is used for viscosity control, to limit shrinkage and as a coefficient of thermal expansion. 2.Calcium carbonate is commonly used in a number of paint and coating applications. It is used as an extender, an agent to either reduce or enhance gloss, an extender / spacer for titanium dioxide, a rheology modifier and as a paint and coating additive to densify the product. 3.Calcium carbonate products help to reduce water demand, compound shrinkage and cracking, as well as reducing overall compound cost in joint compound applications. 4.Calcium carbonate is a low oil absorption ingredient used for carpet backing to lower total manufacturing cost while maintaining excellent mechanical properties. Our calcium carbonate grades add weight to the backing assisting the carpet in laying flat once installed. 5.Calcium carbonate has a high carrying capacity and allows powders to be reconstituted very easily.
