The filling of heavy calcium carbonate can enhance the deposition and permeability of primer on the surface of the base layer. The debugging in the industry will also be different, and the supplementary functions will also be different. Let's understand how heavy calcium carbonate powder is specifically operated and its functions:


In thick paint, heavy calcium carbonate can thicken and thicken the coating and play a filling and leveling role. Therefore, in thick paint, heavy calcium carbonate and light calcium carbonate are usually added. The addition of heavy calcium carbonate can reach 24.6% - 78.5%. In topcoats, that is, in finishing coats, semi-gloss and matte paints adopt the method of adding extender pigments to reduce gloss. Calcium carbonate is an ideal matting filler. In coatings, putty is used to fill the base surface and is the middle layer of the overall coating. No matter what kind of putty, a large amount of fillers need to be added. The main filler in putty is heavy calcium carbonate. A small amount of lithopone is added to increase viscosity and prevent the paint layer from being loose. At the same time, precipitated calcium carbonate is appropriately added for grinding after drying.


Heavy calcium carbonate can play its role as one of the additives in multicolored coatings to achieve the purpose of reducing material costs and improving decorative effects. Our company mainly sells heavy calcium carbonate powder. Welcome to purchase any products you need.
