Introduction to the characteristics of bentonite

The water absorption of cast bentonite is approximately 5 times its own mass. After adsorption, the volume expands to several to ten times the original volume, forming a gel-like substance, and the pigment and filler particles are encapsulated in the coating. Prevents particles from settling. As an inorganic thickener, it has certain applications in the production of paints. The coating has the characteristics of good thickening effect, good suspension, good thixotropy, and convenient storage and construction.

It has good suspension and dispersibility in aqueous medium and can release charged particles as a dispersant to improve the suspension of water-based coatings. Adding a proper amount to architectural coatings can make the coatings less prone to precipitation, stratification and uniform color, thus improving the suspension stability of coatings.
