BK-500

Products Specifications:

BK^®-500 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 toluene, xylene, 200#solvent oil, naphtha and other aromatic and aliphatic compound.
☆ Consistent in rheology and thixotropy development.
☆ Good anti-sagging property and anti-sediment property.
☆ Easy of dispersion

2. Typical Properties:

Color	Appearance	Density	Moisture (@105℃,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000℃ )
Light Yellow	Free Flowing Powder	1.5g/cm³	≤3.5%	≥95%	≤42%

3. Typical Applications:

●Alkyd paint	●Bituminous paint
●Solvent epoxy paint	●Inks(Mineral oil)
●Polyester paint	●Chlorinated rubber paint
●Adhesive

4.      Incorporations:

BK^®-500 belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, BK^®-500 does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.

It can also be added while grinding or after grinding without polar activator. If add it into low polar solvent systems first, better performance can be expected. Meanwhile, high speed shear can also imrove the dispersion greatly.

5.      Recommended Levels:

The amount of BK^®-500 rheological additive required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.3%-2.5% based on the total formulation weight.
