Industrial coating applications: how Coatex’s rheology modifiers can help you?

Industrial coating applications: why rheology is critical to apply the coating?

For industrial coating applications as for other markets, one critical requirement is to formulate long-lasting performance coatings. Several factors strongly contribute to the durability of a coating.

In order to have a durable coating, beyond paint quality and surface preparation, the coating application and the method used are key!

And coating rheology properties have a strong influence on the efficiency of the application method and on the coating thickness control.

Thus, adjusting the flow properties and the viscosity of your coating formulation is essential.

Coatex's rheological additives can help you meet this objective and formulate industrial coatings that can be effectively applied!

For industrial coating applications, several application processes are applicable including spray, dipping, curtain and brush.

Let's review some of these application modes and explain how you can benefit from Coatex's rheology modifiers performance for your industrial coating applications.

Various application processes for Industrial coating applications

For industrial coating applications, some of the traditional application methods frequently used are:

blue arrow Spray

Spray application Spray is the application mode for many industrial coating applications (factory or field-applied).

Rheology profile is critical when the paint is sprayed-applied. And it is not an easy task!

If the viscosity is too high, it can cause surface defects such as orange peel, grainy texture and also a lack of gloss. On the contrary, if the viscosity is too low and the film thickness too high, you can have sags in coatings. In addition, you can face some issues (gun tip blocked) when trying to pump a highly viscous material with fillers that have packed.

The paint has to exhibit good flow properties and to be easy to manipulate while being sprayed. The viscosity has also a strong influence on the equipment used to apply the paint.

Moreover, the paint has to regain its initial viscosity within a short time. Thus, it can be effectively sprayed-applied in thicker layers without running or sagging.

Coatex can help you by recommending the right rheological additives, specifically adapted to spray applications,and which can help you adjust the rheology profile of your industrial coatings:

Thixol™ 53L or Coapur™ XS 71 used in combination with Coadis™ 123 K dispersant allows you to formulate high-quality and eco-friendly waterborne coatings.

blue arrow Dipping

An effective dipping operation depends, among others, on the flow properties of the coating and the anti-settling properties.

Indeed, in order to apply a similar film thickness from the top to the bottom of the parts, paints have to exhibit the required flow. Otherwise, fatty edges can develop at the bottom due to an excess of coating which drains. In addition, thanks to the viscosity control, you can adjust the film thickness.

Finally, avoid pigments sedimentation in dip tanks is critical for an optimized application process.

To address these aspects, part of the solution is to use the right rheological additives.

Coatex rheology additives can help you tailor the behavior of your coating during the dipping process, as shown in the below video. You can select the most appropriate thickener based on your needs and the required effect.


Thanks to the following Coatex's rheology modifiers, you can formulate industrial coatings exhibiting the flow properties compatible with dipping application:


blue arrow Curtain

One of the main issues in curtain coating is to maintain the stability of the curtain coating film and have a continuous flow. Indeed, if the film tears, this causes coating defects.

Specific newtonian thickeners with well controlled elastic behavior can help in this matter providing the desired film resistance.

In addition, they provide the ideal viscosity enabling coating uniformity & quality and a constant film thickness.

Finally, it is critical to avoid pigments sedimentation in tanks in order to keep an homogeneous coating formulation to be applied. And Coatex's additives can help!

For curtain coating, Coatex can recommend the following rheological additives:
No matter how your industrial coatings are applied, Coatex can offer the rheology modifiers
that match your application requirements!
