BK®-887L is
a modified bentonite for water-based systems
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.

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.
