Rheological modifierCP-250A Rheological modifierCP-250A is a kind of new organoclay rheological additive. Rheological modifieris 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 modifierCP-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 modifierCP-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.
