When it comes to self - leveling plaster, one crucial component that often goes unnoticed but plays a significant role is the defoamer. Self - leveling plaster is designed to create a smooth, flat surface with minimal effort. However, air bubbles can form during the mixing and application process, which can compromise the quality and appearance of the finished surface. A high - quality defoamer can effectively eliminate these air bubbles, ensuring a flawless finish. As a defoamer for self - leveling plaster supplier, I'd like to share some insights on recommended defoamer brands and products.
The Importance of Defoamers in Self - Leveling Plaster
Before delving into specific defoamer brands, it's essential to understand why defoamers are so important in self - leveling plaster. During the mixing of self - leveling plaster, air is often incorporated into the mixture. These air bubbles can cause a variety of problems, such as surface voids, pinholes, and reduced strength. Additionally, air bubbles can affect the flow and leveling properties of the plaster, leading to an uneven surface.
Defoamers work by reducing the surface tension of the liquid, allowing air bubbles to coalesce and rise to the surface more easily. Once at the surface, the bubbles can burst, eliminating them from the plaster. This results in a smoother, more uniform surface with improved mechanical properties.
Factors to Consider When Choosing a Defoamer
When selecting a defoamer for self - leveling plaster, several factors need to be considered:
- Compatibility: The defoamer must be compatible with the self - leveling plaster formulation. Incompatible defoamers can cause issues such as phase separation, reduced adhesion, and poor performance.
- Efficiency: The defoamer should be highly efficient at eliminating air bubbles. This means it should work quickly and effectively, even at low dosages.
- Stability: The defoamer should remain stable throughout the storage and application process. It should not break down or lose its effectiveness over time.
- Environmental Impact: With increasing environmental concerns, it's important to choose a defoamer that has a minimal impact on the environment. Look for defoamers that are biodegradable and free from harmful chemicals.
Recommended Defoamer Brands and Products
Based on my experience as a defoamer supplier, I'd like to recommend the following defoamer products:

DEFOAMER 34987 is also stable over a wide temperature range, making it suitable for use in different climates. -
DEFOAMER 1056
DEFOAMER 1056 is another great option for self - leveling plaster. It is a silicone - based defoamer that provides superior defoaming performance. Silicone defoamers are known for their high efficiency and long - lasting effect. DEFOAMER 1056 has excellent compatibility with most self - leveling plaster systems and can be used at low dosages. It also helps to improve the flow and leveling properties of the plaster, resulting in a more uniform finish. You can find more information about DEFOAMER 1056. -
DEFOAMER 1012
DEFOAMER 1012 is a non - silicone defoamer that is ideal for applications where silicone is not preferred. It offers good defoaming performance and is compatible with a variety of self - leveling plaster formulations. DEFOAMER 1012 is environmentally friendly and has a low odor, making it suitable for use in indoor applications. This defoamer effectively reduces air entrainment and improves the surface quality of the plaster. Check out DEFOAMER 1012 for more details.
Application and Dosage
The application and dosage of the defoamer are crucial for achieving the best results. In general, the defoamer should be added to the self - leveling plaster during the mixing process. It's important to follow the manufacturer's instructions regarding the dosage rate, as this can vary depending on the specific defoamer and plaster formulation.
Typically, the dosage of the defoamer ranges from 0.1% to 1% by weight of the plaster. However, it's recommended to conduct small - scale tests to determine the optimal dosage for your specific application. This will ensure that you achieve the desired defoaming effect without over - or under - dosing the defoamer.
Quality Control and Testing
To ensure the quality and performance of the defoamer, it's important to conduct quality control and testing. This can include testing the defoaming efficiency, compatibility, and stability of the defoamer. Various testing methods can be used, such as the shake test, the bubble test, and the microscopy analysis.
By conducting regular quality control and testing, you can ensure that the defoamer meets the required standards and performs as expected. This will help you to deliver high - quality self - leveling plaster products to your customers.
Conclusion
Choosing the right defoamer for self - leveling plaster is essential for achieving a smooth, bubble - free surface with excellent mechanical properties.
