Rheological Additive for Water-Based System
1. Advantages:
☆ High gelling efficiency in water-based systems. Can replace traditional  cellulose ether thickening agent.
☆ Excellent thixotropy property, sag resistance and viscosity control.
☆ Prevent hard settlement of pigment/fillers.
☆ Ease of incorporation and Ease of dispersion.
☆ Suite to wide PH range.
☆ Good corrosion resistance and stable viscosity in different temperatures. Good bio-stability and heat resistance.
☆ Has apparent level limitation.Viscosity increases dramatically when exceeds certain amount.

4. Incorporations:
BK-887LÂ can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
Â
A. Â Water.
B. Â BK-887L(Dispersing at high speed shear for 15-30minutes).
C. Â Other additives(film-forming agent,dispersing agent,defoaming agent, etc).
D. Â Pigment and filler (Mixing and dispersing).
E. Â Emulsion (Mixing).
F. Â Post correct.
Â
5. Recommended Levels:
The amount of BK-887L 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.
