Hectorite organoclay

Hectorite organoclay,In our production plant we produce a lithium-based bentonite and a calcium-based bentonite. These bentonites made from different raw minerals are similar in their actual properties, but there are some slight differences for different specific applications.

Most customers request this mainly when they apply organic bentonite | Hectorite organoclay to oilfield drilling fluids, usually requesting lithium bentonite.

Hectorite organoclay

CP-21 is a new style of organoclay rheological additive made from bentonite. It is used in solvent and resin systems covering low polarity to medium polarity range.

It demonstrates excellent dispensability compared with conventional grades. It is a good replacement of CP-20 in aliphatic systems, especially in applications where the super dispensability attribute should be utilized as advantage. 

Properties

Composition                     Organic derivative of a montmorillonite clay

Appearance                      Fine powder, light yellow

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

Bulk density                       0.40~0.60g/cm3

Fineness (<74μm, %)               ≥98%

 

Advantages

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

Application

  • Paints & coatingswith solvent of low to medium polarity, especially for medium and long oil alkyd paint, acrylic 
  • Printing ink.
  • Lubricant Grease, ink, sealant.
  • Cosmetic
  • Cleaning agent

 

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-21 should be evaluated.

Safety

All safety information is provided in the Material Safety Data Sheets for Zhejiang Camp-Shinning New Material Co.,Ltd..

 

Package

Kraft paper bag with PE liner or multi-wall paper sacks or customized. 25kg/bag or 22.68kg/bag or customized

Storage

CP-21 has a shelf life of 2 years, and should be stored in ventilated cool and dry place.

Application of Hectorite organoclay  

Used for oilfield drilling:  

Hectorite organoclay bentonite is suited for base oil, including synthetic mineral oil and diesel oil.

 Applied in paint coatings.

Organophilic clay is suitable for paints and coatings including water-based systems, paint coatings, and oil-based system coatings.

Applied to lubricating grease.

Bentonite, as well as modified bentonite, can be applied in grease. This includes lubricants for water-based systems and lubricants for oil-based systems.

Applied in cosmetics.

Organic clay bentonite clay can be used in cosmetics, including nail polish, toner, lotion and so on.It mainly utilizes the thixotropy of organic bentonite clay, making cosmetics have better thickening performance.
