Organoclay chemistry

Organoclay chemistry, because of its own high-quality thixotropy and in different applications to play its unique properties, such as in paints and coatings it played an important anti-settling properties and rheological properties, in the oilfield drilling mud he played a suspension properties.

In ink and grease, he played a good thixotropic properties, etc. In short, organic bentonite has been an indispensable chemical additive in various industries. Our technical team will recommend the appropriate type of organoclay for each application.

What is organoclay?

Montmorillonite is modified by quaternary amine salts to give it better hydrophilicity and some other chemical properties, such as rheological properties, anti-settling properties, anti-sagging properties and so on.

Currently in different industrial fields, Organoclay chemistry plays a different performance and function.

For example, in paints and coatings, organic bentonite mainly play its better rheological properties.

In cosmetics it is mainly to play a better thixotropic properties.

In the field of oilfield mining, suspension properties and organic bentonite’s own pore-clearing ability makes him become a good suspending agent in oilfield mining. Organic bentonite and other chemicals between the compatibility, also makes it in the application of the formulation is not affected by other chemicals.

organoclay composition:

Organoclay chemistry consists of natural bentonite minerals and organic cations. At the same time there are basic knowledge also contains other organic compounds, such as surfactants and so on, these surfactants can further enhance the performance of organic bentonite to realize its function in different applications.

Organic bentonite in addition to montmorillonite ore as raw materials, but also need to add quaternary amine salts to carry out modification.

Organic Clay bentonite, in waterborne and solventborne paints and coatings, organo clay improves the phenomenon of pigment delamination, so that the storage time to get a long period of time to stabilize, and at the same time it is in the anti-flux hanging performance and anti-settling performance also plays an important role in the performance of the organic bentonite.

In short, organic bentonite clay so that there is a coatings and paints to greatly enhance the adhesion, stability and performance is also improved.

 Currently our largest sales volume of application areas is the application of organic bentonite to oilfield drilling mud fluid, including fracturing fluid.

organoclay can mainly play the role of suspension, in the oil-based mud, organic bentonite is indispensable suspending agent. In cosmetics, especially nail polish and moisturizing cream emulsion, organic bentonite is a good rheological additives.

In some newspaper ink, gravure ink, Organoclay chemistry is a high-quality thixotropic agent. Currently in the grease lubricant, the addition of organic bentonite, so that it is this formula to achieve anti-settling and anti-sagging as well as good rheological properties.

  In conclusion, Organiclay Bentonite is an indispensable chemical additive for viscosity control in your thickening applications.

For different applications, our engineers and technical sales department will recommend the appropriate model to meet your requirements for different properties. We welcome you to ask us about Organoclay chemistry and we will help you to realize the double advantages and competitiveness in terms of price and performance.
