Modified Organoclay CP-250A is a kind of purified and modified bentonite rheological additive, designed especially for using in Grease based on synthetic oils such as vegetable oil, polyester oil. It has high gelling efficiency, fine thixotropy and perfect anti-settling.

Properties

Composition                      Organic derivative of a montmorillonite clay

Appearance                       Fine powder, light yellow

Moisture content (105℃,2hr)         ≤3.5%

Loss on ignition (1000℃)            34%-36%

Bulk density                       0.42g/cm3

Fineness (<74μm, %)               ≥98%

Advantages

• High efficiency
• The gel is of light colour and high clarity
• Easy to use, no need to pregel
• Eliminate polar activator
• Consistent development of rheology
• Can be used to post correct

Application

CP-250A is used in the following applications:

• Grease Lubricant(the base oil is synthetic oil such as middle-high viscosity petroleum, mineral oil, diester oil, polyester oil, vegetable oil etc.)
• Wood coating 

Using

When it is used in Grease Lubricant, polar activator is needed. Polar activator is acetone/water(95/5). The dosage of activator is 20%-30% of the weight of CP-250A. And also high shear can promote the dispersing of CP-250A.

Organoclay Adding procedure as follows:

1. If condition permits, heat the base oil to 60~70℃
2. Add CP-250A while stirring, addition level is 7%-10% of the total formulation. Stir  5~10minutes
3. Add polar activator, addition level is 2%-3% of the total formulation. Then add other additives, stir 25~30m
4. Use pump to help it pass colloid grinding and homogenizer.
5. Deair, filtrate, pack.

Note: With High-speed dispersant of grinding machine, and properly prolong the dispersing time, better gelatin performance can be reached.

The Lubricanting grease which uses organoclay as thickener will own high dropping point, thus can be used under high temperature and presents good impermeability and water resistance.
