| Topic | Guidance |
|---|---|
| Dosing | Start 10–50 ppm; increase to 100–200 ppm for severe foam. Add at turbulence point upstream. Avoid overdosing (can stabilize foam). |
| RO/Membranes | Use RO‑grade only; dechlorinated feed; follow membrane OEM. Clean if flux/rejection suggests fouling; avoid mixing neat with cationic polymers. |
| CIP/High pH | Use alkali‑stable grade. Effective during caustic CIP; confirm with line trials. |
| Food/NSF | NSF/ANSI 60 options available for potable/process water; use within local limits. |
| Storage | Non‑DG. Store 5–35 °C; protect from freezing/heat; mix before use. |
| Applications | Packaging | Storage & Handling |

|
• RO pretreatment, CIP tanks, wastewater and biological
systems.
• Pulp & paper whitewater, coatings/adhesives, fermentation. • Where silicone carryover is unacceptable. |
• 25 kg cans; 200 kg drums; 1,000 kg IBCs.
• Private‑label on request. |
• Non‑DG. Rotate stock FIFO; gentle agitation before use.
• Consult SDS for PPE and spill response. |
