Ideal Thixotropy Tetraallkyl Ammonium Bentonite

BK-886Bis an organoclay (tetraallkyl ammonium bentonite) for solvent-basedsystems of low to mediumpolarity.1. Advantages:
☆High gelling efficiency overlow to mediumpolarity organic liquids.
☆Ideal thixotropy ,anti-sagging,anti-sediment property.
☆Imparts particle suspension, preventing hard settling of pigment and fillers.
☆Exerts strong film reinforce action in organic binder systems.
☆Good dispersion performance.
☆Upgradeversionof BK-886.2. Typical Properties:ColorAppearanceDensityMoisture

4. Incorportions:
BK-886Bbelongs to the conventional type of organoclay group, which requires mechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organoclayplatelet stacks.Polar Activator:Dosage of polar activator (such as 95%ethanol, 95%methanol,95%acetoneorpropylene carbonate)is30%-50% by weight ofBK-886B.It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.
5. Recommended Levels:The amount of BK-886Brheology modifierrequired depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-2.0% based on the total formulation weight.6. International Countertypes:Bentone®38, Claytone®40,Tixogel®VP-A,Perchem®44,Bengel®434
