Silicone
The results are largely linked to the nature and type of silicone used with the machine.
We have a strong experience of how our machines work with silicone and we strongly advise to use the S110 silicone of the German brand Otto Chemie (see link to their website hereunder)
This silicone is a neutral, one-component silicone made for window water proofing. Its density is around 1g/cc.
The silicone needs to be coming in sealed 30kg pails, which wall is equipped with an airtight plastic liner, together with a dessicant bag and a polystyrene round plate.
