Rheological modifiers clay

Rheological modifiers clay can be used in: greases: to optimize lubrication and reduce wear. Also in printing inks: for precise color rendering and improved print quality.

In adhesives and sealants and anti-corrosion coatings as well as in container coatings and asphalt coatings, it optimizes road performance and improves driving safety.

As a member of the conventional organoclay family, its potential is unlocked by mechanical energy, the shear force of highly efficient dispersing equipment, and the right amount of polar activator.

The amount to be added depends entirely on the characteristics of the target organic system and the desired degree of thickening or other specific properties.

Properties

Composition                     Organic derivative of a montmorillonite clay

Appearance                      Fine powder, light yellow

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

Loss on ignition max, %( 1000℃)    (26.0±1.5) %

Advantages

• High purity, low silica content.
• Fine dispersion and particle size.
• Good self-activated property.
• Gel is very transparent and of light color
• High
• Cost effective.

Application

CP-21A is used in the following applications:

• Lubricating grease, mainly in grease based on mineral oil.
• Paints including decorative paint, industrial paint.
• Ink.
•  
• Sealants and adhesive.

Using

It is a super dispersible grade that can increase flexibility in paint manufacturing. It can be added directly in powder under high shear condition. Addition level is commonly 0.1%~1.0% (7%-10% in greases) of total formulation by weight. Polar activator can be eliminated, but small dosage of polar activator is helpful to achieve better performance.

When non-aliphatic solvent presents, the effectiveness of CP-21A should be evaluated.
