Air introduced during mixing can cause pinholes, surface craters, oil spots, lower slurry density, and inconsistent finished-product quality in cement- and gypsum-based materials.
For manufacturers of self-leveling compounds, grouts, waterproof mortars, decorative mortars, gypsum products, and prefabricated components, selecting an effective powder defoamer is essential for controlling unwanted air and improving product consistency.
Myield Chemical offers the AGIETAM® powder defoamer series, including DF-011, DF-G07, and DF-H06, for different dry-mix mortar and construction material applications.
Why Use Powder Defoamers in Dry-Mix Mortar?
Powder defoamers can be blended directly with cement, gypsum, fillers, cellulose ethers, redispersible polymer powder, and other solid raw materials.
Their main benefits include:
- Rapid removal of unwanted air bubbles
- Improved slurry and hardened-product density
- Reduced pinholes, craters, and oil spots
- Better surface smoothness and uniformity
- Easy incorporation into dry-mix production
- Stable performance at low dosage
- More consistent production quality
The most suitable grade depends on the binder system, formulation additives, mixing conditions, temperature, and required surface quality.
AGIETAM® DF-011: Versatile and Long-Lasting Foam Control
AGIETAM® DF-011 is a non-ionic polyether-based powder defoamer suitable for concrete, mortar, gypsum, and other cementitious systems.
It provides rapid and long-lasting defoaming performance while also improving wetting, slurry fluidity, and ease of application. Its anti-floating-oil properties help reduce surface defects, while its free-flowing powder form supports easy dispersion during production.
Typical applications:
- Self-leveling compounds
- Grouting materials
- Repair mortars
- UHPC
- Gypsum flooring
- Artificial stone
- Cement and gypsum boards
- Gypsum molds and sculptures
- Composite cementitious systems
The recommended dosage is generally 0.05%-0.20% of the total dry-mix weight, or approximately 500-2,000 grams per metric ton.
DF-011 is suitable for manufacturers seeking a versatile, low-dosage defoamer for multiple cement- and gypsum-based product lines.
AGIETAM® DF-G07: Reliable Performance at Low Temperatures
AGIETAM® DF-G07 is a highly effective powder defoamer designed for neutral and alkaline construction material systems.
It provides good foam control, helps improve slurry density, reduces floating-oil defects, and offers good compatibility with commonly used mortar additives. One of its key advantages is reliable defoaming performance under low-temperature conditions.
Typical applications:
- Cementitious grouts
- Self-leveling cement
- Tile grout and caulking compounds
- Interior and exterior putty
- Gypsum prefabricated boards
- Waterproof mortar
- Decorative mortar
The recommended dosage is generally 0.10%-0.20% of the total mortar weight.
DF-G07 is a strong choice for alkaline formulations, cooler production environments, and systems requiring broad additive compatibility.
AGIETAM® DF-H06: Fast Defoaming for High-Quality Surfaces
AGIETAM® DF-H06 is a powder defoamer based on polyether surfactants and a dry powder carrier.
It rapidly removes bubbles introduced through mechanical mixing or chemical reactions. Under suitable conditions, defoaming can generally be completed within approximately 40-90 seconds after mixing.
DF-H06 can also help eliminate black oil spots and is particularly suitable for products with demanding surface-quality requirements.
Typical applications:
- Surface self-leveling compounds
- Grouting materials
- Tile grouts
- Interior and exterior putty
- Gypsum boards
- Bonding mortars
- Gypsum plaster
- Waterproof mortar
- Decorative mortar
- Cement and gypsum prefabricated components
The recommended dosage is generally 0.10%-0.20%, although it may be adjusted after testing for more demanding applications.
DF-H06 is recommended when rapid bubble release, cleaner surfaces, and reduced visible defects are the main formulation priorities.
How to Select the Right Grade
Choose DF-011 for broad cement- and gypsum-based applications requiring rapid and long-lasting foam control, improved wetting, and good slurry flow.
Choose DF-G07 for neutral or alkaline systems, low-temperature conditions, and formulations requiring good compatibility with other construction additives.
Choose DF-H06 for self-leveling materials, grouts, decorative mortars, and prefabricated components where fast defoaming and surface appearance are especially important.
Formulation Recommendations
For the best results:
- Dry-blend the defoamer evenly with other powder ingredients.
- Begin testing within the recommended dosage range.
- Keep the water ratio and mixing procedure consistent.
- Compare slurry density, flow, bubble-release speed, and surface appearance.
- Confirm final performance through laboratory and production-scale trials.
The optimum dosage should balance foam control, workability, mechanical performance, surface quality, and formulation cost.
Improve Your Mortar with the Right Defoamer
Unwanted air can affect the appearance, density, strength, and consistency of dry-mix construction materials.
The AGIETAM® DF-011, DF-G07, and DF-H06 series provides targeted foam-control solutions for different cement-, gypsum-, and mortar-based formulations.
Myield Chemical can recommend a suitable grade based on your application, raw materials, operating temperature, required surface quality, and target dosage.
