Rheological modifier CP-250A
Rheological modifier CP-250A is a kind of new organoclay rheological additive. Rheological modifier is high purified and special modified. It is used in systems covering low polarity, medium and high polarity range solvent and resin system.
  

Properties
Composition                      Organic derivative of a montmorillonite clay
                 Appearance                       Fine powder, white
                 Moisture content (105ºC,2hr)         ≤3.5%
                 Loss on ignition (1000ºC)            34%-36%
                 Bulk density                       0.40~0.60g/cm3
                 Fineness (<74μm, %)               ≥99.5%
           Dispersion fineness (μm)            ≤10

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.

Application
                     Rheological modifier  CP-250A is used in the following applications:
  • Paints including top grades paint, decorative paint, industrial paint, traffic paint etc.
  • Inks
  • Grease.
  • Sealant
  • Cosmetic
  • Cleaning agent


Using
1. Pre-gel method
A. Polar activator is not necessary:
a. Main solvent xylene: 95~92%
b. CP-250A: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 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 Rheological modifier 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
Rheological modifier  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.
