Organic Bentonite
Description
708YB is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity.
Key Features
1.High gelling efficiency over low to medium polarity organic liquids, especially in aromatic compounds.
2.Ideal thixotropy property and anti-sediment property.
3.High viscosity and excellent thickening property over a wide temperature range.
4.Imparts particle suspension, preventing hard settling of pigment and fillers.
5.Exerts strong film reinforce action in organic binder systems.
Applications
●Acrylic paint ●Alkyd paint ●Anti-corrosion paint ●Baking paint ●Bituminous paint ●Chlorinated rubber paint ●Polyester paint ●Primer paint | ●Road paint ●Inks(mineral oil) ●Inks(Nitro) ●Adhesive ●Putties and sealant ●Lubricating grease ●Cosmetics ●Waster water treatment |
Typical Properities
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% |
Incoprporations:
708YB 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 reachthe proper level of delamination of the organoclay platelet stacks.
Polar Activator: Dosage of polar activator (such as 95%ethanol, 95%methanol, 95%acetone or propylene carbonate) is 40%-60% by weight of 708YB
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
Recommended Levels:
The amount of 708YB 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.
