Organo clay

Organo clay CP-40 is an organoclay (modified bentonite), designed especially for use in solvent based system. It can be used widely in solvents from low polarity to medium-high polarity.

Organo clay Properties

Composition                      Organic derivative of a montmorillonite clay

Appearance                       Fine powder, light yellow

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

Loss on ignition (1000℃)            28%-31%

Bulk density                       0.53g/cm3

Fineness (<74μm, %)               ≥98%

Organo clay Advantages

• High gelling efficiency,high viscosity
• Wide application range, it can be applied in all low, middle and high polarity range
• Produce reproducible thixotropic consistency over a wide temperature range
• Imparts particle suspension, preventing hard settling of pigment and fillers
• Exerts strong film reinforcing action in organic binder systems

Organo clay Application

   CP-40 is used in the following applications:

• Marine paint, Industrial paint, heavy-duty, anticorrosion paint such as bituminous coatings, epoxy paints, chlorinated rubber paints
• Grease
• Inks
• Sealant

Organo clay Using

CP-40 disperses under high shear and requires a polar activator for best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% Methanol) is needed. Normally addition level of polar activator is recommended to be 45%~60% of CP-40 in weight. If in xylene system, addition level of polar activator is about 30%-40% of CP-40 in weight.

Pre-gel is made as below procedure.

1. Charge solvent to mill
2. Slowly add CP-40 (6-10% by weight of total pre-gel) to mill under agitation.
3. Mix at high speed for 5 minutes.
4. Add polar activator.
5. Mix at high speed for 5 minutes

Regarding the application of organic bentonite and its application in different industrial fields, we have continuously improved its performance through repeated testing, especially in terms of rheological properties, performance, performance, and sulfur resistance.

Our market experience over the past 20 years has helped us accumulate a large number of practical cases.

The reason why we improve product quality is that we are willing to work with our users to continuously improve our products, continuously improve our quality, and increase our market share.

In fact, the production and application of organic bentonite in China has a history of more than 30 years. It is a kind of Montmorillonite, that is, an organic amine complex. As the main raw material, bentonite uses the growth structure of Montmorillonite in intercalated soil and the characteristics of being able to disperse into colloid in water or organic solvents, and realizes the technical level through ion exchange.

Organic bentonite is made of organic covering agent, In oily systems. The water-based system can show good suspension performance, lubricity and film forming performance, and its water resistance and high temperature resistance are also extremely excellent, especially in the coating industry.

Because its thixotropy and thickening properties are fully recognized, and it is also widely used in the fields of ink lubricating grease oil station and other fields and is welcomed by users.

It has to be said that organic bentonite has already determined its unique properties when it feels inferior.At present, our production processes are mainly divided into two types from a technical perspective: wet process and dry process.

This kind of organic bentonite, called organic bentonite gel, can be directly used, that is, you can directly add dry powder, or fully disperse the whole organic bentonite by pre gel.
