Penyerapan air bentonit tuang adalah lebih kurang 5 kali jisimnya sendiri. Selepas penjerapan, isipadu mengembang kepada beberapa hingga sepuluh kali ganda isipadu asal, membentuk bahan seperti gel, dan zarah pigmen dan pengisi terkandung dalam salutan. 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.
