Silicone Defoamer Guide: Emulsion vs Compound vs Food Grade
Silicone defoamers work in diverse media: aqueous, non-aqueous, and food-safe systems. Form and active silicone content are the primary selection criteria.
| Spec | ZEMSIL DF-100 | ZEMSIL DF-200 | ZEMSIL DF-W | ZEMSIL DF-F | ZEMSIL DF-C |
|---|---|---|---|---|---|
| Form | O/W emulsion | O/W emulsion | Water-based compound | O/W emulsion | Neat compound (100 %) |
| Active content | ~10 % | ~20 % | ~20 % | 10–30 % (FDA) | ~100 % |
| Dilution required | Optional | Optional | Dilute 1:10–50 | Optional | Yes, 0.01–0.5 % |
| Food-safe (FDA) | No | No | No | Yes (21 CFR 173.340) | No |
| Best for | Wastewater, paper | Paper, textile | Aqueous paint, latex | Food, pharma, fermentation | Paints, coatings, rubber processing |
How to choose
- ▸Wastewater treatment and paper: DF-100 (10% emulsion, safe dilution ratio, low cost).
- ▸Textile wet processing and high-foam paper: DF-200 (20% emulsion, stronger active dose).
- ▸Water-based paints and latex: DF-W (water-based compound, compatible with aqueous systems).
- ▸Food, beverage, or pharmaceutical processes: DF-F (FDA 21 CFR 173.340 compliant).
- ▸Rubber processing or high-load coatings: DF-C (neat 100% compound, maximum efficiency).
