Product Description

              
Organophilic montmorillonite CP-720A

organophilic montmorillonite CP-720A is a kind of new organoclay rheological additive. organophilic montmorillonite is high purified and special modified. Organoclay Bentonite 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
                      Organophilic montmorillonite CP-720A 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.organophilic montmorillonite CP-720A: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 organophilic montmorillonite CP-720A.
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 organophilic montmorillonite CP-720A.
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 organophilic montmorillonite CP-720A 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
organophilic montmorillonite 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.
