DFP-810 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
High-temperature and strong-alkali resistance – reliable under harsh mixing and processing conditions.
Fast dispersion – powder form blends uniformly with dry raw materials without affecting flowability.
Environmentally and regulation friendly – free of REACH SVHC substances, suitable for export and for medical / public-infrastructure materials.
DFP-880 Powder Defoamer (Non-silicone)
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
Non-silicone and phosphorus-free – reduced surface defects and regulatory risks.
Fast defoaming with long-term suppression – balanced process efficiency and product stability.
Easy to handle in powder form – high compatibility with dry formulations, convenient storage and dosing.
WDF-862 | Mineral-oil-based Waterborne Defoamer
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
Rapid micro-foam break + long-term suppression – suitable for both application and storage stability.
High active content (99%) – low dosage and good cost efficiency.
Regulation friendly – free of REACH SVHC substances, suitable for export and medical / public-project coatings.
WDF-816 | Dilutable Silicone High-Efficiency Defoamer
Q1: Why essential?
In wastewater treatment, industrial cleaning, and adhesive production, foam often causes tank overflow, sensor malfunction, and reduced process efficiency.
WDF-816 is a highly concentrated silicone defoamer that achieves rapid defoaming and long-term suppression at very low dosage, significantly improving system stability.
Q2: What scenarios?
Wastewater treatment systems
Industrial cleaning processes
Adhesives
General surfactant- and polymer-foaming systems
Q3: Key benefits
High dilution ratio – flexible use, lower transportation and inventory costs.
Compatible with silicone emulsions – high formulation flexibility.
Full regulatory compliance – free of SVHC, NP/APEO, and RoHS restricted substances.
WDF-887 | Polyether Liquid Defoamer
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
High compatibility with cement additives and inorganic systems.
Non-silicone, NP/APEO-free – avoids surface defects and environmental concerns.
Stable handling – transparent, low-viscosity liquid, easy to meter and dose continuously.
