(1) Coating 
Calcium carbonate can be used as paint filler, with concentrated distribution of particles, high Whiteness; 
It can be used as a body filler in the coating to increase its dispersion or from the skeleton in the products, it is a good filler and white pigment. In oil paint, it can enhance the deposition and permeability on the primary surface of primer. Calcium carbonate can improve product performance, reduce product costs and improve processing performance, Heavy calcium carbonate is one kind of micro-fine calcium carbonate made of high pure and white Calcite in wet grinding method. 

(2). Papermaking 
Calcium carbonate can widely be used in the paper industry, offer filling and coating effects in the paper, with an excellent dispersion, and can increase the fill volume, improve product performance and processing and mechanical properties, etc. It can significantly reduce paper costs, increase the whiteness of paper, improve printing performance and optical properties of paper, so that it decrease the cost of products. Calcium carbonates one kind of micro-fine calcium carbonate made of high pure and white Calcite in wet grinding method. 

(3). Sealant 
Calcium carbonate is widely used as the filler in adhesives and sealants. Wet grinding calcium carbonate has good fluidity and dispersion for it is processed by special coupler: Can improve product performance, reduce product costs and improve processing performance. Coupler processed calcium carbonate has better dispersion, thus it can be dispersed in adhesive evenly and improve the quality of products.
