Fracture Grade Organoclay Rheological Additive , Rapid High Yield Paint Thickener

Organoclay fracture grade

Organoclay fracture grade Self activating with highly effective and rapid high yield in mineral oil based

Organoclay CP-34 is an organophilic clay (modified bentonite), designed especially for use in solvent based system. It can be used widely in solvents from low polarity to medium-high polarity. Rheological additive furnish the drilling mud(fluid) with good suspension,wall-protection and anti-filtration properties.No need for polar activator in oil drilling application and maintain stable physical performance under the pressure of 108 at the temperature of 230ºC.

   1, Properties

4, Using

CP-34 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 or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 40%~50% of CP-34 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-34 in weight.

Pre-gel is made as below procedure.

  • Charge solvent to mill
  • Slowly add CP-34(6-10% by weight of total pregel) to mill under agitation.
  • Mix at high speed for 5 minutes.
  • Add polar activator.
  • Mix at high speed for 5 minutes.
