BP-186 is an organo clay (modified montmorillonite), designed especially for use in solvent based system including intermediate and low polarity polarity range organic liquild.
Advantages
1 Exerts gelling efficiency over a wide range of intermediate and low polarity.
2 Easy dispersing.
3 The gel is colourless and of high clarity.
4 Produce reproducible thixotropic consistency over a wide temperature range
5 Imparts particle suspension, sag resistance without impairing flow and leveling, preventing hard settling of pigment and fillers.
6 Exerts strong film reinforcing action in organic binder systems.

Using
BP-186 disperses under high shear and requires a polar activator (30%~40%) for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 30%~40% of BP-186 in weight.
