Description: Products Specifications: BK®-883 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity. 1. Advantages: ☆ High gelling efficiency over low to medium polarity organic liquids, especially in aromatic compounds. ☆ Ideal thixotropy property and anti-sediment property. ☆ High viscosity and excellent thickening property over a wide temperature range. ☆ Imparts particle suspension, preventing hard settling of pigment and fillers. ☆ Exerts strong film reinforce action in organic binder systems. 2. Typical Properties: Color Appearance Density Moisture (@105℃,2hrs) Fineness through 200 mesh Loss on Ignition ( @1000℃ ) Light Yellow Free Flowing Powder 1.7g/cm3 ≤3.5% ≥98% ≤35% 3. Typical Applications: ●Acrylic paint ●Road paint ●Alkyd paint ●Inks(mineral oil) ●Anti-corrosion paint ●Inks(Nitro) ●Baking paint ●Adhesive ●Bituminous paint ●Putties and sealant ●Chlorinated rubber paint ●Lubricating grease ●Polyester paint ●Cosmetics ●Primer paint ●Waster water treatment 4. Incorportions: BK®-883 belongs 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 organoclay platelet stacks. Polar Activator: Dosage of polar activator ( such as propylene carbonate, 95%ethanol , acetone or 95% methanol) is 40%-60% by weight of BK®-883. 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®-883 rheological additive required 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.
