Cleaning agent


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 CP-720B.

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-720B.

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 Organo bentonite CP-720B 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

Solvent Borne Organoclay 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.
