BK®-882 is an organoclay (tetraallkyl ammonium bentonite) for oil-based drilling mud (fluid).
1. Advantages:
¡î Good suspension,thixotropy and stability in crude oil,diesel oil systems. ¡î Easy 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. ¡î Maintain stable physical performance under the pressure of 108 at the temperature of 230¡æ.
