BP-183B is an organo clay (modified montmorillonite), designed especially for use in oil based system. It can be used widely in solvents from low polarity to high polarity.
Advantages
1. High gelling efficiency
2. Wide application range, it can be applied in all low, middle and high polarity range.
3. Produce reproducible thixotropic consistency over a wide temperature range
4. Imparts particle suspension, preventing hard settling of pigment and fillers.
5. Exerts strong film reinforcing action in organic binder systems.

Using
BP-183B disperses under high shear and requires a polar activator for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol) is needed. Normally addition level of polar activator is recommended to be 45%~60% of BP-183B in weight.
