Quick selection
- Oil-based systems, hydrophobic
- CENSIL 17
- Liquid powdering, high absorption
- CENSIL 698
- Powder systems, high absorption
- CENSIL 688
Where we add value
- Support powdering of defoamer oils or liquid actives into a system that is easier to handle and dose.
- Improve anti-caking and stability in oil-based defoamer systems through hydrophobic silica.
- Help balance knock-down speed, persistence, compatibility, cratering and surface-oil risk.
Who this track serves
- Defoamer manufacturers, defoamer compounders and industrial additive channels.
- Coatings, paper, textile, wastewater, construction-chemical and fermentation additive companies.
- Customers who need powder defoamers, liquid powdering or system-stability materials.
Grades on this track
A hydrophobic route for oil-based defoamer systems, and two high-absorption powder routes aimed at liquid powdering and powder-system stability. Mineral oil, silicone oil, polyether and waterborne systems each need their own compatibility testing.
We publish the selection logic, not the numbers. Data sheets are issued per enquiry so the figures match the current supplier revision and your application.
Typical values for orientation only, not a specification. The current supplier technical data sheet governs for quotation, COA and customer testing — request it for the grade you are evaluating.
How to run the trial
| Test dimension | What to watch | What it tells you |
|---|---|---|
| Knock-down speed | How fast foam is eliminated | Tells you immediate defoaming power |
| Persistence | Foam regrowth over time | Tells you sustained stability |
| Compatibility | Fit with resin, emulsion, oil or water phase | Avoids separation, surface oil and cratering |
| Liquid powdering | Whether the powder still flows after absorption | Tells you if powdering is feasible |
| Storage stability | Settling, caking or loss of activity over time | Tells you product reliability |
Where we sit against the reference brands
How we approach it
Confirm whether the customer runs mineral oil, silicone oil, polyether or a waterborne system first, then decide between the hydrophobic route of CENSIL 17 and the high-absorption powdering route of CENSIL 698 / 688.
