This media is very difficult to eliminate and can result in small sticky areas where the rubber has failed to cure.
Choice of silicone very important and you should consult with the supplier.
WSF has given me no problems with silicone curing , but the surface roughness can make mould stripping difficult.
Painting with primer and flatting where possible will help as with this pattern for a 7 !/4" gauge steam locomotive part.

Polished WSF is easier to strip , as you would expect.
You can see several examples of moulds taken from printed patterns at;
