BK®-887L is a modified bentonite for water-based systems
1. Advantages:
¡î High gelling efficiency in water-based systems. Can replace traditional cellulose ether thickening agent. ¡î Excellent thixotropy property, sag resistance and viscosity control. ¡î Prevent hard settlement of pigment/fillers. ¡î Ease of incorporation and Ease of dispersion. ¡î Suite to wide PH range. ¡î Good corrosion resistance and stable viscosity in different temperatures. Good bio-stability and heat resistance. ¡î Has apparent level limitation.Viscosity increases dramatically when exceeds certain amount.

4. Incorporations:
BK®-887L can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
A. Water. B. BK-887L (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®-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.
