Application scope of polarity and dispersion conditions of gel production of BT series organobentonite thickening rheological additive

When using BT series organobentonite thickening rheological additive, users shall firstly determine appropriate type according to the polarity of solvent, then determine the application method according to dispersion conditions.

When using BT series organobentonite thickening rheological additive, please follow the steps hereunder:

. Determine the polarity;

. Select appropriate type;

. According to dispersion conditions, determine the application methods.

Application scope and Dispersion Conditions of BT Series Organobentonite Rheological Additive:
