4. Incorporations:
BK
®-187
can be added directly in powder form. No need for polar actiator or pre-gel.
Recommended procedures are as follows:
A. Water
B. BK-187
(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
®-187 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.
