What role talc powder plays in latex paint

Date of release:2018-09-05 Author: Click:

Talc powder has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inertia, excellent covering power, softness, luster and strong adsorption. Because the crystalline structure of talc is layered, it has the tendency of easy splitting into scales and special lubrication. It has important effects in many areas, such as latex paint. Latex paint is playing a more and more important role in our daily production. What is the important effect of talc powder in latex paint? The Runze talc powder manufacturer has made the following introduction.

The application of talc powder in latex paint can improve the workability, leveling, hardness and corrosion resistance of the coating. The application of talc powder in putty powder can improve the batch scraping property of putty. The amount of talc powder in latex paint should be restricted. If the dosage is too large, it is easy to cause caking deposits. And watch for temperature changes. In latex paint, not only the whiteness and fineness of talc powder are related, but also the temperature.

The main component of talc powder is talc and magnesium silicate. What we need to pay attention to here is the water-bearing magnesium silicate. Pure talc is usually colorless and bright, or white, but usually talc contains impurities, which will show a light brown, light green or light brown. Therefore, we can see the quality of talc powder through the color. So we can judge when we buy and use it.
