6 Application Scenarios You Need Antifoaming

Knowing the different antifoaming agents application is essential. It helps you make better decisions when choosing the most suitable one.


Difference between Antifoam and Defoamer

Antifoaming Agent

-Antifoam prevents foam from forming in the first place.

-Often added to formulations to stop foam from appearing during application.

-Reducing the surface tension of liquids, preventing bubbles to form more.



-Defoamer destroy existing foam.

-Break down existing bubbles and reducing foam volume.

-Typically contains ingredients that disrupt foam structure, causing bubbles to collapse.


Antifoaming for Self Leveling Mortar

When mixing cement mortar with water, air gets trapped, creating lots of foam. Foam reduces production efficiency and harms the quality of self-leveling cement mortar.


Self-leveling mortar requires mixing techniques. If the mixing speed is too slow, the mixture will mix unevenly, and if it’s too fast, it will create too many bubbles. This is where antifoaming steps in to fix the issue.


1. Reduced foam formation during mixing.

2. Improved workability and fluidity.

3. Prevention of surface defects caused by foam.

4. Increased productivity and material consistency.

Is powder antifoam a better option?

Powder doesn’t contain moisture, which is why it works well in dry powder mix products.


Another benefit of powder defoamer is that it only requires a minimum dosage to stop foam for a long time. The powder product is very easy to carry around. It’s effective in controlling foam in hot and high-alkaline liquids.


Anyway, each type of antifoaming product may have its pros and cons. Choose the most suitable one for your application.

Why do we need antifoaming in building materials?

The air in the foam prevents the dispersion of the material or filler;


Resulting in insufficient utilization of equipment, affecting production quality;


Foaming affects the mixing speed and prolongs the blending time.


This resulted in the use of film in making holes, small holes, and so on.

What is the difference between anti-foaming agents and defoamers?
The difference between anti-foaming agents and defoamers lies in their application and timing. Anti-foaming agents are used preventatively to inhibit foam formation before it occurs. They are usually added during the manufacturing process to prevent foaming issues.
On the other hand, defoamers are used reactively to eliminate existing foam. They are introduced after foam has already formed, to break down the foam and reduce its volume.
Both anti-foaming agents and defoamers serve the same ultimate purpose of controlling foam. But, they are applied differently based on whether the goal is prevention or elimination. Understanding these distinctions is crucial in selecting the appropriate product for specific industrial processes where foam management is essential.
What is an antifoaming agent?

Industrial processes are susceptible to potential problems if foams are not eliminated. As a result, adding antifoaming agents during the process is essential to reducing and preventing foam formation. Defoamers commonly include insoluble oils, polysiloxanes, alcohols, stearates, and glycols. Each chemical has unique properties that enable them to break down and prevent foam formations. Defoamers can be added either before or after foaming occurs for maximum effectiveness.

How does a foaming agent work?

Defoamers, or antifoaming agents, are important chemical additives in industrial processes. It mainly reduces and prevents foam formation. These two terms are often used interchangeably. Defoamers eliminate existing foam, while antifoaming agents block additional foam from occurring. The use of these chemicals is an essential part of many industrial processes.

What are defaming agent and deformers used for?

Formulations such as paints, inks, coatings, adhesives, and emulsion polymers can cause foam during production. If left unchecked, the foam can result in various detriments—for example, surface defects or production inefficiencies. To effectively address the foam issue, antifoaming agents are crucial components for successful outcomes.

What are the types of antifoaming?

The types of antifoaming agents vary. They come in three types: silicone-based, oil-based, and water-based antifoams. Silicone-based antifoams work well in high temperatures. Oil-based antifoams are suitable for oil-based systems. Water-based antifoams are commonly used in water treatment.
