(10%suspension )
Light White Free Flowing Powder 1.6g/cm3 ≤10.0% ≥95% 6-12

3.      Typical Applications:
Water-based paint&coatings  
Emulsion paint  
 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.
