Non-Silicone Defoamer & Antifoaming Agents — Mineral Oil, Fatty Alcohol, Polyether | INVINO®
Silicone-Free Antifoam Solutions — No Cratering, No Film Defects, No Silicone Contamination
INVINO® non-silicone defoamers are antifoaming agents that control industrial foam without using silicone (PDMS) as the active component. They use mineral oil, fatty alcohols, polyether block copolymers, or polyether esters as active ingredients. Non-silicone formulations are required when silicone residues would cause cratering and fish-eyes in coating films, incompatibility with AKD or rosin paper sizing systems, contamination in food-grade processing, or surface defects in high-quality printing inks.
INVINO supplies four non-silicone active component portfolios: mineral oil compounds for waterborne paints, adhesives, and printing inks; fatty alcohol emulsions for paper machine wet-end white water and pulp washing; polyether block copolymers for fermentation bioreactors, wastewater treatment, and cementitious construction; and polyether ester variants for wet-process phosphoric acid and aggressive chemical systems. All are 100% active content — no water carrier — and available in 25 kg drums, 200 kg barrels, and 1,000 kg IBC totes.

Mineral Oil Defoamer
For waterborne architectural paints, industrial coatings, adhesives, and printing inks. 100% active, APEO-free. Eliminates cratering and fish-eyes without the silicone contamination risk that causes recoatability failures in multi-layer coating systems.
Fatty Alcohol Defoamer
For paper machine wet-end white water systems and kraft pulp brownstock washing. Silicone-free, alkali-stable, and fully compatible with AKD and rosin sizing — the standard antifoam choice for sensitive paper grades and food-contact packaging board.
Polyether Defoamer
EO/PO block copolymers for fermentation bioreactors (citric acid, yeast, antibiotics), industrial wastewater aeration tanks, MBR units, pulp mills, and cementitious construction. Biologically inert. Food-grade and Halal grades available.
Polyether Ester Defoamer
Chemically modified polyether ester variants for wet-process phosphoric acid production, industrial washing systems, and leachate treatment. Designed for aggressive acidic or high-electrolyte environments where standard polyethers lose performance.
Non-Silicone Defoamer — Technical Guide
What is a non-silicone defoamer?
A non-silicone defoamer is an antifoaming agent that controls industrial foam without using silicone (polydimethylsiloxane) as the active component. Non-silicone defoamers use mineral oil, fatty alcohol, polyether block copolymers, or polyether esters as active ingredients. They are required in applications where silicone residues would cause problems: cratering and fish-eye defects in waterborne coating films; incompatibility with AKD or rosin paper sizing; contamination concerns in food-grade fermentation; and surface defects in sensitive printing inks and adhesives.
What is the difference between silicone and non-silicone defoamers?
Silicone defoamers (PDMS-based) provide strong, fast foam knockdown across a wide temperature range — they are the best choice for wastewater treatment, textile dyeing, and high-temperature industrial systems. However, they can deposit silicone oil residues on surfaces, causing cratering in coating films, fish-eyes in paints, and incompatibility with AKD/rosin paper sizing.
Non-silicone defoamers eliminate the silicone contamination risk entirely. They are the required choice for waterborne architectural coatings, paper machine white water systems, food-grade fermentation, and any application with silicone-free certification requirements. The trade-off: non-silicone defoamers typically require more careful grade selection and dosage calibration than silicone alternatives.
Which industries require non-silicone defoamers?
Industries where silicone-free antifoam is required or strongly preferred:
- Waterborne Paints & Coatings — Silicone residues cause cratering and inter-coat adhesion failures. → Mineral oil defoamers
- Pulp & Paper Manufacturing — Silicone contaminates AKD/rosin sizing and causes paper defects. → Fatty alcohol defoamers
- Fermentation & Food Processing — Food-grade and Halal certification requires silicone-free actives. → Polyether defoamers
- Adhesives & Printing Inks — Silicone causes delamination and ink fisheye defects. → Mineral oil defoamers
- Phosphoric Acid Production — Corrosive acidic environment requires acid-stable non-silicone actives. → Polyether ester defoamers
How to Select the Right Non-Silicone Defoamer
Non-silicone defoamer selection depends on your process medium chemistry and the reason silicone is excluded:
- Film appearance critical (coatings, inks, adhesives) → Mineral oil compound defoamers
- Paper machine sizing compatibility required → Fatty alcohol emulsion defoamers
- Biological systems (fermentation, wastewater) → Polyether block copolymer defoamers
- Aggressive acid or high-electrolyte systems → Polyether ester defoamers
- Dry-mix systems (mortar, detergent, agrochemical WP) → Powder defoamers (silicone on inorganic carrier)
