4.      Incorporations:
BK®-887A can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
A.            Water.
B.           BK-887A (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®-887A rheological additive required depends upon the specific system and the degree of thickening or other properties desired. Addition levels are typically between 0.5%-3.0% based on the total formulation weight.
