Thixotropic agents in paints | Organoclay Rheological Additive
Thixotropic agents in paints is a kind of organoclay rheological additive, somebody called it Thixotropic agent with good advantages in oil drilling mud and fracturing. Thixotropic Rheology additive can produce very good thixotropic gel.
Disperses easily in less time with less shear ,high performance viscosifier for low aromatic, all mineral oil and synthetic base fluids.

Dispersion fineness (μm) ≤10
Thixotropic Rheology Advantages
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.
Paints including top grades paint, decorative paint, industrial paint, traffic paint etc.is used in the following applications:
Oil Drilling Mud
1. Pre-gel method
A. Polar activator is not necessary:
a. Main solvent xylene: 95~92%
b. Rheology organoclay CP-720B:5~8%
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
2. Procedure of adding gel: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 .
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 Organo bentonite Thixotropic Rheology 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
Thixotropic agents in paints 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.
