rheology modifiers in paints

Rheology Modifier

Rheology modifier is widely used in paints, greases, inks and drilling mud.Rheology modifier mainly plays a better thixotropic property,rheology , thickening and dispersion.

Rheology modifiers for waterborne paints

Rheology Modifier For Water Borne Paints

Rheology modifier is widely used in water-based system, also known as inorganic bentonite.In the inorganic system of paint, ink grease, the use of rheology modifier can play a better thixotropy and dispersion.

Rheology modifiers for solvent based paints

Rheology Modifier For Solvent Based Paints

Rheology modifier is used in solvent system paint, it mainly plays a good dispersion, anti settling and anti sagging performance. These properties play a very good role in the long-term storage of paint after the use of rheology modifier.

1,What Is Rheology Modifier? 

Rheology modifier is provided by Camp Shinning New Material Co.Ltd.It is made of amine treated bentonite with good thixotropic in paints and cosmetics,special for waterborne paint and oil which has good has good suspension and thickening.

 In industrial production, such as the production of paints, inks, greases and oil drilling mud, it is very challenging to make the products have better rheological | rheology properties and achieve the stability and suspension of the whole formula.We need to make the whole formula achieve a better suspension performance and a high degree of stability after the rheology modifier, which is our obvious requirement and goal in the operation. Achieve better dispersion is also one of our goals.


However, in the process of production operation, when adding rheology modifier, we need to be very careful to realize a problem, that is, adding rheology modifier at the same time to prevent high viscosity, because high viscosity will affect the construction operation, resulting in the whole formula can not be used because of high viscosity.


Camp Shinning’s rheology modifier plays a good role in a thickening agent and improving viscosity. Its role is far more than its own. It plays a role in rheological properties in the formulation,  Rheology modifier is also a good embodiment of the thixotropy in the formula. Therefore, the rheology modifier is sometimes called the thickening agent, also called ORGANOCLAY rheological additive. Its good performance of rheology modifier can build the stability of the whole formula, making it easy to flow and pour during operation.


  For example, when our paint or lubricant is stored for a long time, it is easy to precipitate. Then when we need to use it, it will cause too high viscosity due to precipitation, and it can’t be poured out, transported out, and operated well. But after using rheology modifier, Camp Shinning’s rheology modifier has an outstanding function in anti-settlement performance.


 Therefore, when developing the formulation of rheology modifier, Camp Shinning fully considered the role of rheological modifiers that need to be embodied, so that the structure of the whole formulation can effectively control the viscosity, making our customers soluble in water-based system and solvent-based system, easy to use our rheology modifier and providing better stability, rheological properties, and suspension properties.

2, What Are The Good Properties Of Rheology Modifier Used In waterborne paints?   

When rheology modifiers for waterborne paints,the properties includes are as follows:

  • High gelling effectiveness,  rheology modifiers can form gel even at 2% in water
  • Easy dispersing.
  • Gel is transparency and of light color
  • Prevents pigment Settling
  • High thixotropy, Good anti-sag property

3, What Products Could Enhance Rheological Properties Of Drilling Fluid?

  • Rheology modifiers could enhance the rheological properties of drilling fluid.
  • Rheologyadditive is used for drilling oil mud because of its thixotropic property.

Thixotropy is also called gel strength. When Rheology modifiers is used for oil drilling fluids, it acts as a thixotropic additive and suspending agent. The thixotropic property of Rheology modifiers helps oil drilling fluids to suspend rock cuttings produced during oil drilling. It ensures these rock cuttings are moved to the surface and prevents them from falling back into the drilling shaft when drilling stops.

The suspension ability of Rheology modifiers in oil drilling muds prevents tools from sticking in the oil well. It also reduces the collection of solid materials at the bottom of the hole. 

4, What types of rheology modifier does Camp Shining produce for oil drilling muds?

As a leading Rheology modifiers manufacturer, Camp Shining produces 6 grades of Rheology modifiers for oil drilling muds and fracturing fluids.

Our 6 series of Rheology modifiers for oil are CP-250, CP-982, CP-992, CP-169, CP-EZ, and CP-150.

Depending on the base oil you use as your drilling fluid, Camp Shining can offer you a suitable Rheology modifiers grade to help you get the best drilling results. Our Rheology modifiers can be used for mineral oil, crude oil, synthetic oil, and diesel.

The table below shows you Camp Shining’s grades of Rheology modifiers and the best base oil it matches best.

We recommended our CP-250A and CP992 for diesel, synthetic oil, and mineral oil. Our CP-169, CP-EZ, and CP-982  are recommended for diesel applications. For an economical-grade diesel, CP-169 is suitable for you.

If you looking for self-activated organoclay, our CP-EZ and CP-982 are the ones you have to look out for. We recommend using these grades when diesel-based drilling mud has no water.

5, What are the benefits of using Camp Shinning’s organophilic clay for my oil drilling muds and fracturing fluids?

Camp Shining’s organophilic clay provides you the following massive benefits when used for your oil drilling and fracturing fluids.

  • It acts as an excellent thixotropic additive that makes your oil drilling mud suspend rocks and other solids materials effectively.
  • Camp Shining’s organophilic clay is a high-performing suspension agentfor your oil field fluids. It helps your oil drilling fluids to maintain suspension over a wide temperature range.
  • Our excellent grades of organophilic is a super quality rheological modifier for all your oil drilling fluids, giving your fluids excellent flowing capability.
  • Camp Shinings make your oil drilling mud disperse easily and yield effectively.
  • When you use Camp Shining’s organophilic clay for your oil drilling muds, you won’t need any chemical activator.

6, What is Water Based Rheology Modifier?

At present, the water-based rheology modifier is a popular and widely used thickener in the market. Rheology modifier is widely accepted by the public because of environmental protection.Water based rheology modifier, also known as additives of inorganic system.When the water-based rheology modifier is applied to the water-based system of paints, lubricants, inks, etc., the formulation can play a good rheological role, greatly improve its thixotropy. The raw material of water-based rheology modifier is bentonite clay. After improvement, the end-users really need the additives of water-based system.Rheology modifier is a white powdery chemical.  The advantage of water-based rheology modifier is that it is very easy to use, and has high stability and environmental protection performance. It can maintain and improve stability and suspension performance at the same time, and it can be easily stirred into the formula without Pre gel expansion. At the same time, rheology modifier can still show better performance under high temperature and high pressure.

Rheology modifier is one of the most common rheological additive. Rheology modifier has a colloidal structure.After using activation, it disperses and has more outstanding performance.  Our common activators are methanol, ethanol and propylene carbonate, some users regard water as an activator, which is a good recommendation.

In the process of our research and development of the modified rheology modifier formula, we are also interested in comparing with other modifiers with the same performance. In the comparative test, our rheology modifier formula has higher      effective control of viscosity,better storage stability and suspension performance.

 Therefore, our organic bentonite formula has those advantages, Camp Shinning’s rheology modifier is a kind of modified bentonite which is very popular and widely accepted in the market.

With the leading technology and unique formula expertise of Camp Shinning in the industry for many years, our incomparable additives and rheology modifier can help our customers obtain the best rheological properties and thixotropic properties in their formulas, so that our users can produce the best products.
