These fine ground powders have tightly controlled particle distribution to allow for high loading levels and reduced resin demand.
Special care is given to control large particles to provide smooth finishes.
To achieve the desired high solids loading capability, the OMYA products for this application contain a broad particle size distribution to allow optimal particle packing, thereby reducing resin usage. The role of ground calcium carbonate in joint compounds is to serve as a functional mineral of high brightness with low binder demand to accomplish excellent shrinkage control. These products are available for shipment in 50 pound paper bags, semi-bulk bags and bulk pneumatic trucks and railcars. The role of ground calcium carbonate in latex carpet compounds is to increase the solids and improve the drying characteristics of the compound. Additionally, careful attention is paid to controlling the color in a narrow range to provide a consistent color to the carpet backing.
