CENSIL 17 is a hydrophobic silica in Sensilchem's defoamer silica family. The hydrophobic, anti-caking route for oil-based defoamer systems. Compatibility with mineral oil, silicone oil, polyether and waterborne systems is always confirmed separately. It is quoted on the defoaming & system stability track. Specifications, the technical data sheet and a COA are issued per enquiry; the fit is confirmed on your own line.
Two roles: making an oil-based system stable, and turning a liquid defoamer into a powder that still flows.
A high-absorption candidate for liquid powdering — taking a defoamer oil or liquid active onto a carrier that remains easy to handle and dose.
The companion high-absorption route, aimed at liquid powdering and powder-system stability work.
Run CENSIL 17 beside the material you use now, in your own system at the same loading, and read the dimensions below. We send a short test plan with every sample set.
| 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 |

Technical data sheet at the current supplier revision with the test method behind each figure, a specification sheet, a certificate of analysis for every lot, SDS / MSDS and a use statement for the destination market. Sensilchem does not publish specification tables on the website; request the set by email and it arrives matched to your application.
The material you use now, the formulation or resin, the equipment and the target you need to hit. That is enough for us to say whether we have something worth testing.
