3. Typical Applications:
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 (PH:6.0-12.0, but most suitable between 7.0-8.0). 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 0.2%-1.0% based on the total formulation weight.
