Will Gasoline, Oil, Denatured Alcohol Affect Ordinary Sanitary Silicone or Sealants?

Question

Hi. I have a question. Will gasoline, oil, denatured alcohol dissolve ordinary sanitary silicone?
Alternatively, is there any silicone or silicone-like sealant that the above liquids will not dissolve? Please give me some suggestions.

Sanitary is not suitable buy a car, what do you want to seal?

If it does not solidify, it will wash off with gasoline. Use the silicone used in the moto technique, but I haven't seen the colorless ones, that's what you mean.

Thanks for the quick replies. The point is, I have a handmade stainless steel item and I wanted to seal it. Has contact with the fluids I have replaced. I want to seal it so that it does not leak and the sealant does not dissolve. It does not have to be colorless.

Gasoline dissolves silicone 100%. I experienced it myself. As for the other two substances, I'm not sure. Maybe some acrylic or two-component distal or Technicoll glue.

The car silicone Technicoll petrol, nor any of the substances mentioned above, dissolves. Of course, it must be solidified, otherwise it can be washed off with water.

Silicones, as long as they have a little solvent in them, can be washed off with many liquids, but if the ribbon is 100%, even acetone will not dissolve it.

Gasoline should not dissolve the silicone. Alcohol too.
All stories of silicone dissolving by various liquids are mainly due to the misuse of silicone. If someone seals the fuel tank of a scooter without cleaning the surface and the fuel is poured in when it is wet, the joint lets go.

Once a friend of mine sealed a carburetor in a Fiat 126p with silicone. As he was doing the entire engine overhaul, the silicone must have dried properly before he started it. Then he struggled with a clogging carburetor for a few days. The silicone has grown into small balls under the influence of gasoline. It was true that it was about 15 years ago, so now silicones are more resistant to gasoline.

robokop · Answer

The term idiot for this acquaintance is too mild. Not under the influence of gasoline, but too much stuffing it, and in addition, wherever it falls - the squeezed out litter fell wherever they wanted. In general - sanitary silicones can be used in environments where there are neither oils nor substances similar to them - it is, among others, o that the silicone gasket is detached from the surface and crumbles.

telecaster1951 · Answer

Exactly. Gasoline, crude oil, engine or cooking oil should not dissolve the silicone, but it should detach it from the surfaces to be joined. Especially when dealing with constantly flowing fluid. It will then be washed away.
