Organosilicon defoamers are emulsion/oil-based high-efficiency defoamers made primarily of polydimethylsiloxane (PDMS)*, combined with emulsifiers, hydrophobic silica, etc. They are currently the most widely used and cost-effective broad-spectrum defoamers in industrial applications.

Core Parameters

Appearance: White milky liquid (emulsion type) / Colorless transparent oil (oil type)

Solid content: 10%–30% (customizable)

pH: 6–8
Temperature resistance: -40℃～180℃
Applicable pH: 3–12

Features: Ultra-low dosage (1–10ppm), extremely fast defoaming, excellent foam suppression, acid and alkali resistance, high temperature resistance

Main Applications

Coatings / Inks / Adhesives: Eliminates foam during production and application, preventing pinholes and craters

Textile Printing and Dyeing: High-temperature dyeing vats, pretreatment, printing defoaming

Paper Making / Pulping: Black liquor, white water, coating defoaming

Water Treatment: Aeration tanks, desulfurization towers, landfill leachate

Chemicals / Fermentation: Antibiotics, monosodium glutamate, citric acid fermentation

Metalworking Fluids: Cutting fluid, cleaning fluid foam control

Product Advantages

✅ High efficiency and low consumption: ppm-level addition, low cost

✅ Broad compatibility: Suitable for both aqueous and oil phases

✅ High stability: Stable in high temperature, acid and alkali environments

✅ Safe and environmentally friendly: low toxicity, physiologically inert, suitable for use in food and pharmaceutical grade systems.
