BK-100A
Products Specifications:
BK®-100A is an organoclay
(tetraallkyl ammonium bentonite) for solvent-based systems of low, medium and high polarity.
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.
