Powder Defoamer

Q1: Why essential?

In high-solids and high-shear processes such as dry-mix mortars and powder coatings, air is easily entrapped to form fine and stable foam, leading to pinholes, reduced mechanical strength, and surface defects after application.
DFP-810 is able to break foam rapidly and provide long-term foam suppression even at high temperatures (60–90 °C) and in strongly alkaline systems (pH > 9), effectively reducing process risks and stabilizing final product quality.

Q2: What scenarios?

• Dry-mix mortars (self-leveling compounds, cement-based repair materials, tile adhesives)

• Powder coatings

• Diatom mud building materials

• Drilling and cementing materials (can be added after foam formation or pre-formulated as a defoaming component)

Q3: Key benefits

1. High-temperature and strong-alkali resistance – reliable under harsh mixing and processing conditions.

2. Fast dispersion – powder form blends uniformly with dry raw materials without affecting flowability.

3. Environmentally and regulation friendly – free of REACH SVHC substances, suitable for export and for medical / public-infrastructure materials.

Q1: Why essential?

In powder coating and dry-mix mortar systems, conventional silicone defoamers may cause craters, fisheyes, or coating defects.
DFP-880 is a non-silicone formulation that combines fast defoaming with long-lasting foam suppression, stabilizing processing and film appearance without compromising surface quality.

Q2: What scenarios?

• Powder coatings with high appearance requirements

• Dry mortars and decorative building materials

• Coating or post-processing systems where silicone contamination must be avoided (can be added during foaming or at formulation stage)

Q3: Key benefits

1. Non-silicone and phosphorus-free – reduced surface defects and regulatory risks.

2. Fast defoaming with long-term suppression – balanced process efficiency and product stability.

3. Easy to handle in powder form – high compatibility with dry formulations, convenient storage and dosing.

Q1: Why essential?

In waterborne architectural coatings, industrial coatings, and high-gloss finishes, micro-bubbles easily cause pinholes, craters, haze increase, and uneven gloss.
WDF-862 uses a mineral-oil/polymer composite system to quickly destroy micro-foam and maintain long-lasting suppression, ensuring stable coating appearance and production quality.

Q2: What scenarios?

• Waterborne architectural coatings

• Waterborne industrial coatings

• Printing inks

• Adhesives

• High-gloss coating systems

Q3: Key benefits

1. Rapid micro-foam break + long-term suppression – suitable for both application and storage stability.

2. High active content (99%) – low dosage and good cost efficiency.

3. Regulation friendly – free of REACH SVHC substances, suitable for export and medical / public-project coatings.

Q1: Why essential?

In polycarboxylate superplasticizers, premixed mortars, and fiber-cement boards, poor compatibility of defoamers may cause phase separation, oil bleeding, or performance failure.
WDF-887 is a polyether-based, non-silicone defoamer designed for cement and admixture systems to stabilize air content and improve consistency of mechanical strength.

Q2: What scenarios?

• Polycarboxylate superplasticizer production

• Premixed mortars

• Fiber-cement boards

Q3: Key benefits

1. High compatibility with cement additives and inorganic systems.

2. Non-silicone, NP/APEO-free – avoids surface defects and environmental concerns.

3. Stable handling – transparent, low-viscosity liquid, easy to meter and dose continuously.
