Rheological Additive for solvent based system(Organoclay)

Explanation

BK^®-169 is an organoclay (tetraallkyl ammonium bentonite) for oil-based drilling mud (fluid).

1. Advantages:

¡îGood suspension,thixotropy and stability in crude oil,diesel oil systems.

¡îEasy of incorporation. No need for polar activator or making pregel.

¡î Furnish the drilling mud(fluid) with good suspension,wall-protection and anti-filtration properties.

¡îMaintain stable physical performance under the pressure of 10⁸ at the temperature of 230¡æ.
