As a filler, heavy calcium carbonate is widely used in papermaking, coatings, paints, inks, cables, construction supplies, rubber, plastics and other industries. As a filler, it increases the volume of products and reduces production costs. So, let's take a look at the application status of heavy calcium carbonate in the coating industry with the editor.

In the paint production process, heavy calcium carbonate can be used as a white pigment to serve as a skeleton. The addition of calcium carbonate also enhances the deposition and permeability of the primer on the surface of the substrate. At the same time, heavy calcium carbonate is the main putty filler in thick paint, and heavy calcium carbonate can also thicken and thicken the paint, thus playing the role of filler leveling. Therefore, heavy calcium carbonate and light calcium powder are generally added to thick paint, and the addition of heavy calcium carbonate can reach 24.6% ~ 78.5%.

In the top coat, heavy calcium carbonate is a good matting filler. Heavy calcium carbonate can be used as an additive for colorful coatings, which can not only reduce material costs, but also improve decorative effects. Light calcium powder, that is, precipitated calcium carbonate, can be used in colorful coatings. It can be used for color coatings with an oil absorption of about 80%, a particle size of about 15 microns, a specific gravity of about 2.7, and a refractive index of about 1.60; heavy calcium carbonate can also be used.

In the metal anti-rust paint, heavy calcium carbonate is an extender pigment, and it also has a little anti-rust effect. The reasonable control amount of calcium powder in the metal anti-rust paint is 30%.
