Organoclay bentonite
Organoclay bentonite is a rheology modifier. It exhibits good thixotropic properties, resists sagging, resists run-off, and exhibits ideal thickening properties. It is a rheological additive specifically designed for use in solvent-based systems. Organoclay bentonite can be widely used in solvents ranging from low to medium-high polarity in paints, coatings, inks, greases, and drilling muds.

1, Properties
Composition: Organic derivative of montmorillonite clay
Appearance: Fine powder, light yellow
Moisture content (105 ℃, 2 hours) ≤3.5%
Loss on ignition (1000 ℃) 40% -45%
Bulk density 0.40 ~ 0.60 g / cm3
Fineness (<74 µm,%) ≥98%

2, advantages
- High purity, low silica content
- Fine dispersion and particle size
- Good self-activating property. This can eliminate the polar activator.
- Wide range of applications including low and high polarity systems
3, Application
CP-257 is used in the following applications:
- Marine paints, industrial paints, heavy-duty, anti-corrosion paints such as bitumen coatings, epoxy paints, chlorinated rubber paints
- Lubricant, especially recommended for synthetic oil based lubricants such as vegetable oil, polyester oil, etc.
- Ink
- cosmetic
4, using
It can be added directly to the powder under high-shear conditions. The addition level is typically 0.1% to 1.0% (7-10% in grease) of the total formulation weight. In low- and medium-polarity solvents, a polar activator is necessary for optimal performance.
The procedure for adding is suggested below.
- Add resin to the solvent.
- Add CP-257 while stirring slowly.
- Run at high speed for 10-15 minutes.
- Add polar activator (95% ethanol or 95% acetone)
- Run at high speed for 10-15 minutes.
- Add wetting agent and other additives.
- Grinding and the next procedure.
Making a pre-gel can achieve better efficiency. The recommended addition level to the pre-gel is 8-10% of the total pre-gel weight.
Pre-gel procedure as shown below.
- Add solvent or solvent mixture.
- Add CP-257 while stirring slowly.
- Run at high speed for 5-10 minutes.
- Add polar activator.
- Run at high speed for 10-15 minutes.
The polar activator is assumed to be ethanol/water (95/5) or acetone/water (95/5). The dosage of the polar activator is about 10%-35% CP-257 by weight.
5, Note: Organoclay bentonite
The suggested addition levels of our organoclay and polar activator are based on our laboratory testing. The exact dosage for a detailed formulation should be based on user testing.
