1. Advantages:
☆High gelling efficiency over low,medium and high polarity organic liquids.
☆Easy of incorporation.No need for polar activator or making pregel.
☆ Consistent in rheology and excellent thixotropy development.
☆Easy of dispersion especially in styrene and alcohol solvent. Dust-free addition.
☆Excellent anti-sagging property and anti-sediment property.
☆Can replace fumed silica in epoxy resin systems and unsaturated resin systems with better thixotropy performance and more economical price.
☆Upgrade version of BK-100.

4. Incorporations:
BK®-100A belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay,BK®-100A does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
However, in systems like styrene, xylene,200#solvent oil and compund solvent, pre-gel method is also acceptable.
5. Recommended Levels:
The amount of BK®-100A 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%-0.6% based on the total formulation weight. For special purpose, for example, in hand layup unsaturated resin,1-6% is recommended.
