Description
What is Silicone Defoamer?
Silicone Defoamer (also known as a Silicone Antifoam Agent) is a high-efficiency chemical additive formulated with Polydimethylsiloxane (PDMS) silicone fluid emulsified in water with hydrophobic silica particles. It works by lowering surface tension at the gas-liquid interface, rapidly destabilizing foam bubbles, causing them to collapse immediately (knockdown), and preventing new foam formation (antifoaming persistence).
Manufactured in Vadodara, Gujarat by Zeel Product, our industrial silicone defoamer emulsion is non-ionic, chemically inert, non-corrosive, and universally compatible with acidic, alkaline, and high-salinity industrial aqueous systems.

Key Benefits of ZEELCHEM® Silicone Defoamer
🚀 Rapid Foam Collapse
Spreads rapidly over foam lamellae to collapse existing macro and micro foam in under 5 seconds upon addition.
⏳ Long-Lasting Antifoaming
Maintains prolonged antifoam action in continuous turbulence, aeration tanks, and aggressive shear environments.
💰 Cost-Effective Ultra Low Dosage
Extremely effective at economical concentrations (20–100 ppm), significantly reducing overall chemical consumption costs.
🔬 Non-Reactive & Eco-Friendly
Does not react with substrate chemicals, non-toxic to biological sludge in wastewater ETP systems, and eco-safe.
Industrial Applications of Silicone Defoamer
Our silicone defoamer chemicals are widely utilized across diverse manufacturing sectors in India and internationally:
- Effluent & Sewage Treatment Plants (ETP / STP): Eliminates surface foam caused by surfactants, detergents, and biological aeration in municipal & industrial wastewater treatment.
- Textile Dyeing & Processing: Prevents foam formation in jet dyeing machines, yarn dyeing, textile printing pastes, and wet finishing processes without oil spots or fabric staining.
- Pulp & Paper Manufacturing: Controls foam in black liquor washing, bleaching towers, papermaking wet ends, and coating applications.
- Chemical & Agrochemical Processing: Suppresses foam during chemical reaction blending, resin synthesis, fertilizer production, and pesticide formulation.
- Paints, Inks & Coatings: Prevents air entrapment and pinholes during high-speed dispersion, grinding, and application of water-borne latex paints.
- Sugar & Distilleries: Controls heavy foam generated during sugar beet/cane extraction and alcohol fermentation processes.
How to Use & Recommended Dosage Guidelines
- Direct Addition or Pre-Dilution: ZEELCHEM® Silicone Defoamer can be added directly into the foaming system as a concentrate or pre-diluted with 1 to 5 parts of cool soft water.
- Recommended Dosage Rate: Typical starting dosage is 20 ppm to 100 ppm (20 to 100 grams per 1,000 Liters of foaming liquid). Optimization can be conducted via laboratory beaker test.
- Addition Point: Add the defoamer solution upstream at a point of high turbulence or agitation (e.g., aeration tank inlet, pump suction, or mixing vessel) to ensure rapid, uniform distribution.
- Continuous Metering: For continuous processes, automated metering pumps are recommended for maintaining steady antifoaming efficacy.

Frequently Asked Questions (FAQs) – Silicone Defoamer
Q1: What is the price of silicone defoamer per kg in India?
The price of industrial silicone defoamer in India typically ranges from ₹65 to ₹190 per kg depending on the active silicone content percentage (10% to 50%), order quantity, and packaging type. Contact Zeel Product for factory-direct wholesale quotes.
Q2: What is the difference between silicone and non-silicone defoamers?
Silicone defoamers use Polydimethylsiloxane (PDMS) which offers superior thermal stability, lower required dosage (20-100 ppm), and faster foam knockdown across extreme pH ranges. Non-silicone defoamers are mineral oil or fatty alcohol based, suitable where silicone presence is restricted (such as specific automotive paints).
Q3: Is silicone defoamer suitable for ETP / STP wastewater treatment?
Yes. ZEELCHEM® silicone defoamer is specifically formulated for industrial ETP and municipal STP plants. It rapidly destroys surface foam without harming beneficial microorganisms in aerobic or anaerobic biological digestors.
Q4: How should silicone defoamer emulsion be diluted?
Silicone defoamer emulsion can be diluted using cool clean water at a ratio of 1:1 up to 1:5. Gentle stirring is recommended to maintain emulsion stability; avoid high-shear mixing during pre-dilution.
