What is Powder Defoamer?

A powder defoamer is a specialized chemical additive designed to control and suppress foam formation in cement or gypsum mixtures. For many building materials, such as cement, mortar, self-leveling compound, or tile adhesive, foam can be an unwanted side effect that disrupts the subsequent work steps and may even undermine the stability of the construction. It needs defoamers to eliminate or reduce the formation of bubbles and ensure smooth processing of the compound.

5 Key Benefits of NOVASTAR™ Powder Defoamer

Exceptional Foam Eliminating Ability

NOVASTAR™ Powder Defoamer is highly effective at controlling and eliminating foam in mortar mixtures. By destabilizing and rupturing the foam bubbles, NOVASTAR™ defoamer causes them to collapse. This action reduces surface tension and improves air release, ultimately preventing the formation of unwanted foam.

Reduced Mixing Time

NOVASTAR™ Powder Defoamer has a fast foam-eliminating speed, which helps to reduce mixing time and leads to increased productivity.

Excellent Chemical Stability

NOVASTAR™ Powder Defoamer has good chemical stability and is difficult to react with other substances. Adding it to the mortar does not affect the basic properties of the system, allowing smooth application of the mixture.

Consistent Performance

NOVASTAR™ Powder Defoamer helps maintain and strengthen the desired properties of the mortar mixture, such as setting time, compressive strength, flexural strength, and adhesion, without the interference of unwanted foam.

Good Heat, Acid, and Alkaline Resistance

NOVASTAR™ Powder Defoamer is formulated with modified polyether compounds, which are polymers with unique properties that make the powder defoamer have good heat stability, acid resistance, and alkaline resistance.

Multiple Applications of Powder Defoamer

Cement-Based Self-leveling Mortar

Powder defoaming: Powder defoamer can reduce the surface tension of cement paste and make the foam film rupture, thus eliminating these bubbles and holes.

Fluidity enhancement: It can significantly improve the fluidity and the apparent state of the mortar, making the surface flatter and smoother.
Strength enhancement: It can improve the compressive and flexural strength of self-leveling mortar.

Grouting Mortar

Quality improved: Powder defoamer can effectively eliminate the foam in grout and ensure its uniformity and fluidity, thus improving the strength and durability of grout.
Enhanced efficiency: By reducing the generation of foam, it can improve the processing efficiency of grout, shorten the construction period, and reduce construction costs.
Protect equipment: The use of powder defoamer can reduce the maintenance cost of equipment caused by foam and prolong the service life of the equipment.

Waterproof Mortar

Sealing and waterproof: Powder defoamer can help the air bubbles burst, reduce the holes appearing during the curing process, and improve the sealing and waterproof performance of the coating.
Compressive and flexural strength: The defoamer eliminates the holes and defects, which not only improves the compactness of the mortar but also enhances its compressive and flexural strength.

UHPC (Ultra-High Performance Concrete)

Durability: Powder defoamer eliminates air bubbles in concrete by lowering the surface tension of the bubbles, which improves the compactness of concrete, reduces the cavity, and enhances its compressive strength and durability.
Flatter surface: It can make the surface of concrete smoother and flatter, improve the overall appearance quality of the project, and fulfill architectural aesthetics.
Seepage resistance: Defoamer can also reduce the water secretion phenomenon of concrete, reduce its water absorption, and improve seepage resistance.

Frequently Asked Questions about Powder Defoamer

What is the Mechanism of Powder Defoamer in Mortar?

Powder defoamer in mortar can inhibit the formation of foam and destroy the formed foam. The mechanism is that they enter the liquid film to reduce the viscosity of the liquid, forming a new low surface viscosity interface, so that the liquid film loses its elasticity, accelerating the process of liquid exudation, and ultimately making the liquid film thin and rupture.

What are the Influencing Factors of the Defoaming Rate of Powder Defoamer?

What are the Precautions for the Use of Powder Defoamer?

Correct usage amount

When using powder defoamer, the first thing to pay attention to is the usage amount. The right amount is the key to ensuring the defoaming effect. Too little defoamer may not be effective in removing foam, while too much defoamer may affect the performance of the mixture. Therefore, users should determine the optimal amount to use through experimentation based on the specific application scenario and the nature of the foaming system. This not only ensures the defoaming effect but also avoids unnecessary waste.

Avoid excessive mixing

After adding the polyether defoamer, stirring is a necessary step to ensure that the defoamer is evenly dispersed in the foaming system. However, excessive stirring may damage the dispersion performance of the defoamer and reduce its defoaming effect. Therefore, mixing should be carried out in moderation to avoid excessive mixing. At the same time, attention should be paid to safety during the mixing process to avoid the defoamer splashing or splattering.

What are the Storage Conditions of Powder Defoamer?

The storage of powder defoamer is also an important part of ensuring its stability and effectiveness. Defoamer should be stored in a cool, dry, and ventilated place, avoiding direct sunlight and a high-temperature environment. High temperatures and humidity may cause the defoamer to deteriorate or become ineffective. At the same time, storage should ensure that the container is well sealed to avoid the entry of air and moisture. For the defoamer after opening, it should be used as soon as possible to avoid quality degradation caused by long storage time.
