organic clay rheological additive is an organophilic bentonite. Organic clay controls the settling of solids in oil-based drilling muds and other drilling fluids.
organic clay can be used alone or in combination with conventional organoclay gellants.
The solids suspension capacity of a fluid which is already thickened with an organoclay can be increased by the addition of organoclay.
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, white
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 34%-36%
Bulk density 0.40~0.60g/cm3
Fineness (<74μm, %) ≥99.5%
Dispersion fineness (μm) ≤10Advantages
High purity, low silica content.
Easy dispersing, fine particle size. Easy to use, no need to pregel
High viscosity and high thixotropic.
Wide application range. It can be applied in almost all resins and solvents
Gel is very transparent and of light color.
OBM Viscosifier organophilic bentonite CP-250A is used in the following applications:
1. Pre-gel method
A. Polar activator is not necessary:
a. Main solvent xylene: 95~92%
c. Dispersing 5-15min, gel is finished.
B. Polar activator is necessary:
a. In aromatic solvent, the recommend activator is methyl acohol/water (95%/5%)/ acolhol/water (95%/5%), the dosage is 33%-45% based on the weight of CP-250A.
b. In mineral oil (such as 200#), white oil, diesel oil, the recommend activator is methyl acohol/water (95%/5%)/acolhol/water(95%/5%), the dosage is 33%-60% based on the weight of CP-250A.
2. Procedure of adding gel:
A. Charge solvent and resin to mill
B. Slowly add the gel
C. Dispersing 5-10min
D. Wetting agent (if required)
E. Disperse completely to desired fineness
F. Dilute to desired viscosity
3. Add directly with powder
A. Charge solvent and resin
B. Add CP-250A slowly
C. Disperse 10-15min
D .Add polar activator (if necessary)
E. Disperse 10-15min at high speed
F. Add wetting agent and other additive
G. Grind and next procedure
It can be added directly in powder under high shear condition. The addition is recommended to be before grinding procedure to get the best effectiveness. Addition level is commonly 0.1%~2.0%.
If add polar activator and make pre-gel, better efficiency can be achieved.
