2).Characteristics and Application:
BP®-188L water-based bentonite is natural silicon aluminate rheological additive whose main content is hydrophilic special processed montmorillonite with high purity. It has the following characteristics:
1. Strong thixotropy property, can replace cellulose ether thickener.
2. It can be added without polar activator, widely suited PH range (6~12).
3. It owns weather resistance,anti-enzyme and can keep stable viscosity under different temperature.
4. It has excellent bio-stability and heat resistance.
5. It is not easily flocculated and lose color.
6. It has apparent dosage limitation. The viscosity will increase quickly when added exceeds a certain quantity.
Widely used in water-based coatings, emulsion paints, water-based ink, nanometer material, toothpaste, cosmetics etc.
