Product Description
BK-887 is a modified bentonite for water-based systems
1. Advantages:
☆ High gelling efficiency in water-based systems.
☆ Excellent thixotropy property, sag resistance and viscosity control.
☆ Prevent hard settlement of pigment/fillers.
☆ Ease of incorporation and Ease of dispersion.
☆ Suite to wide PH range.
2. Typical Properties:
3. Typical Applications:
4. Incorporations:
BK-887 can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
A. Water (PH:6.0-12.0, but most suitable between 7.0-8.0).
B. BK-887 (Dispersing at high speed shear for 15-30minutes).
C. Other additives (film-forming agent,dispersing agent,defoaming agent, etc.)
D. Pigment and filler (Mixing and dispersing).
E. Emulsion (Mixing).
F. Post correct.
5. Recommended Levels:
The amount of BK-887 rheological additive required depends upon the specific system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-1.0% based on the total formulation weight.
6. International Countertypes: Bentone®EW/LT, Laporte®WH, Attagel®-50
