Bentonite for Drilling Fluids
Introduction to Organoclay
In paints and coatings, organoclays are used as rheological additives to improve the flow qualities, sag resistance, and anti-settling features of the material. The organoclay materials offered by Zhejiang Camp Shinning make it possible for pigments to be dispersed more effectively, which in turn leads to superior color development and an overall improvement in the performance of coatings.
Organoclays are synthetic materials that are derived from naturally occurring clay minerals like montmorillonite and bentonite. The clay surfaces of these minerals go through a process called as organophilization, in which they are changed with organic molecules, most often quaternary ammonium ions. This change bestows distinctive qualities onto the organoclays, including increased rheological control, greater thickening efficiency, and exceptional suspension capabilities, to name just a few.
What is the Purpose of Organoclay Thickeners in Paint?
When we add organoclay to the paint, it becomes thicker and less likely to flow. The better thickness of the paint makes it easier to apply and prevents it from spreading too much or dripping, especially on surfaces that are upright. When the paint becomes thicker, it helps to spread it evenly and uniformly, resulting in a consistent paint thickness.
Organoclays are used in paints and coatings to enhance their flow properties, prevent sagging, and improve their ability to resist settling. The organoclay products from Zhejiang Camp Shinning help to disperse pigments more effectively, which leads to better color development and overall performance of coatings.
What are the Different Types of Paint Thickeners?
The desired qualities and application criteria of the paint formulations may be utilized to direct the selection of the many kinds of paint thickeners, each of which offers certain advantages.
Organoclays are an extremely popular use as paint thickeners. These clays have had their structure altered by the application of organic molecules. Paint compositions benefit from the use of organoclay since it increases viscosity and increases stability. During the application process, they serve to avoid sagging and leaking, as well as enhance the flow behavior of the paint. Also, organoclays, especially the ones from Zhejiang Camp-Shinning is affordable compared to other paint thickeners available in the industry.
2. Hydrogenated Castor Oils
Hydrogenated castor oil is a waxy compound obtained through the hydrogenation of refined castor oil. It is commonly used as a slip additive in paints, plastics, and inks. It also functions as a dispersing agent in carbon papers, plastic color master batches, and ink formulations. Additionally, it can serve as a dispersing additive and flow control agent in sealants, hot-melt adhesives, powder coatings, and more.
3. Polyamides | Bentonite for Drilling Fluids
These are high-performance coatings that are semi-transparent and are designed to preserve wood surfaces that are exposed to the elements. They provide protection against the damaging effects of water, mold, and ultraviolet light. Polyamides are often utilized in wood treatments because of their ability to increase durability while still maintaining the wood’s natural beauty.
4. Silicas |Bentonite for Drilling Fluids
Another kind of thickener that is often used in oil-based paint formulations. Due to the fact that it has a little effect on the color of drying oil, it may be used without significantly altering the overall color hue. When employed in formulas, silica has a rather firm texture, which, when combined with other ingredients, may impart a noticeable texture on the surface of the paint.

Advantages of Using Organoclay as a Thickener in Paint Formulations
Organoclay is a substance that paint manufacturers find helpful in controlling the thickness and flow of their paint formulations. By using this approach, you can avoid the paint from drooping, dripping, or running while you are applying the paint. By doing this, you’ll have more precise control over the paint, and it will enhance the overall look of your project. This product is designed to make it easier for you to apply paint by helping to level it out. This results in a smoother and more even finish, whether you’re using a brush or a roller.
Organoclay-based thickeners are useful in improving the stability and durability of paint formulations. These substances help prevent pigments, fillers, and other components from settling and separating, even when they are exposed to varying temperatures and shear conditions. When paint is stable, it can last longer on the shelf. This means that the quality of the paint remains consistent over time. Many types of paint systems work well with organoclay thickeners. You can add these to different types of paint without any impact on the paint’s performance or other characteristics.
Types of Paint That Uses Organoclay
Bentonite for Drilling Fluids
Organoclay-based thickeners find application in a wide range of paint types. Here are some common types of paint that utilize organoclay:
1. Acrylic Paint Thickener
Zhejiang Camp-Shinning’s organoclay is specifically formulated to enhance the thickening efficiency in synthetic and other organic fluids with medium to high polarity. When incorporated into acrylic paint formulations, this organoclay rheological additive improves viscosity control, allowing for better handling and application of the paint.
2. Oil Paint Thickener
To make it, you mix organoclay smectite with an organic cation. Typically, the quantity of cation utilized falls within the range of 75% to 150% of the clay’s cation exchange capacity. This clay is effective in thickening natural oil systems. If the organophilic clay has a component that occurs naturally, it is more effective in thickening natural oil-based products. The end result is now easier to work with and apply due to improved viscosity control and stability of the oil paints.
3. Latex Paint Thickener
Zhejiang Camp-Shinning CP-180 is a type of organoclay thickener that can be added to latex paint. It has the advantage of being able to disperse well even under high shear conditions. When you combine it with a polar activator, CP-180 works at its best efficiency. Usually, the polar activator makes up around 30% to 40% of the weight of CP-180. Typically, when adding CP-180 to latex paint formulations, the recommended levels range from 0.2% to 2.0%. For optimal outcomes, it is suggested to use a polar activator like 95% ethanol or 95% methanol. When you use a mixture of organoclay thickener and polar activator, it helps to better control the thickness and stability of latex paint formulations.
4. Water-Based Paint Thickener
Specifically designed for water-based systems, the organoclay thickener enhances the viscosity and rheological properties of the paint, ensuring better control during application. It disperses easily in water-based formulations without the need for additional heat or complex mixing processes. The addition levels of the organoclay thickener typically range from 0.2% to 2.0%, depending on the desired viscosity and consistency of the paint.
