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.
6. International Countertype: Bentone®OC
