Method for producing multilayer silicone composites, in which at least two layers consist of cured silicone each with a layer thickness of 0.1 to 200 μm, where each of the individual silicone layers has a thickness precision of ± 5% as measured over an area of 200 cm 2, characterized in that i) a solvent-containing or solvent-free, crosslinkable silicone composition is applied through the slot of a slot die to a moving carrier, ii) subsequently the solvent, if present, is removed from the silicone layer which forms on the carrier film, and the silicone layer is partially crosslinked, so that it has a degree of crosslinking of at least 40% and at most 90%, iii) optionally intermediate layers are applied, to give a 1st layer composite, composed of carrier, one crosslinked silicone layer, and optionally intermediate layers, iv) a solvent-containing or solvent-free, crosslinkable silicone composition is applied through the slot of a slot die to the moving 1st layer composite, v) subsequently the solvent, if present, is removed from the silicone layer which forms on the 1st layer composite, and the silicone layer is partially crosslinked, so that it has a degree of crosslinking of at least 40% and at most 90%, vi) optionally steps iii) to v) are repeated at least once more, vii) there is a final crosslinking of the silicone layers, since only partial crosslinking took place in steps ii) and v), viii) subsequently the resulting multilayer silicone composite can be separated from the carrier, with the following provisos: - the slot die in step i) and iv) is at an angle of between 10° and 90° to the carrier; - the travel speed of the carrier and of the 1st and also further layer composites in steps i) and also iv) is between 0.1 and 1000 m/min; - the dynamic viscosity at 25°C of the silicone composition, measured according to DIN 53019, is between 100 mPa•s and 1000 Pa•s; - the surfaces of the carrier contain no depressions or elevations which are larger than 5% of the film thicknesses to be produced, and - particles which are greater than 1/3 of the individual silicone layer thickness are removed from the crosslinkable silicone composition before it is used. i) a solvent-containing or solvent-free, crosslinkable silicone composition is applied through the slot of a slot die to a moving carrier, ii) subsequently the solvent, if present, is removed from the silicone layer which forms on the carrier film, and the silicone layer is partially crosslinked, so that it has a degree of crosslinking of at least 40% and at most 90%, iii) optionally intermediate layers are applied, iv) a solvent-containing or solvent-free, crosslinkable silicone composition is applied through the slot of a slot die to the moving 1st layer composite, v) subsequently the solvent, if present, is removed from the silicone layer which forms on the 1st layer composite, and the silicone layer is partially crosslinked, so that it has a degree of crosslinking of at least 40% and at most 90%, vi) optionally steps iii) to v) are repeated at least once more, vii) there is a final crosslinking of the silicone layers, since only partial crosslinking took place in steps ii) and v), viii) subsequently the resulting multilayer silicone composite can be separated from the carrier, - the slot die in step i) and iv) is at an angle of between 10° and 90° to the carrier; - the travel speed of the carrier and of the 1st and also further layer composites in steps i) and also iv) is between 0.1 and 1000 m/min; - the dynamic viscosity at 25°C of the silicone composition, measured according to DIN 53019, is between 100 mPa•s and 1000 Pa•s; - the surfaces of the carrier contain no depressions or elevations which are larger than 5% of the film thicknesses to be produced, and - particles which are greater than 1/3 of the individual silicone layer thickness are removed from the crosslinkable silicone composition before it is used.
