Powder defoamer is a solid defoamer mainly composed of special ingredients such as polyether, polysiloxane, and emulsifier. It is used to solve foaming problems in water-based powder systems (such as dry mortar, coatings, and detergents). It features rapid defoaming, long-lasting foam suppression, resistance to high alkalis/acids/temperatures, good compatibility with powder materials, and easy dispersibility. It can be added directly or diluted with water before use, making it an ideal alternative to liquid defoamers in powder systems.
Main Components and Characteristics
Components: A compound of special polyether alcohol esters, polysiloxane, emulsifier, and inorganic carrier.
Characteristics:
Strong defoaming power: Fast defoaming speed and good long-lasting foam suppression.
Stable performance: Resistant to high temperatures, strong acids, strong alkalis, high electrolytes, and high shear.
Good compatibility: Excellent compatibility with various water-based powder systems and surfactants, without affecting product appearance.
Good flowability: Easy to mix with dry powder materials, convenient to use.
Environmentally Friendly and Safe: Moisture-free, non-toxic, and non-flammable/explosive.
Typical Applications:
Building Materials: Dry-mixed mortar, self-leveling compound, putty powder, waterproofing materials, etc.
Cleaning Agents: Metal cleaners, alkaline degreasing powder, powdered detergents, etc.
Coatings and Inks: Powder coatings, water-based paints, stone-like paints, etc.
Water Treatment: Electrolytic water treatment, industrial wastewater treatment, etc.
Others: Pesticide powders, starch, papermaking, textile printing and dyeing, etc.
Usage Methods:
Direct Addition: The powdered defoamer can be directly mixed evenly with the powder, or sprinkled onto the foam.
Add After Dissolving: Dissolve thoroughly in water first, then slowly add the solution to the foaming system.
Dosage: The generally recommended addition amount is 0.1%–0.3% (depending on the system), and the specific amount needs to be determined through testing.
