MORE INFO
Silicone rubbr RTV EC22 for skin contact. Two-component silicone with polyaddition curing. For body moulding and mask making. For very detailed moulding.
For fast and very detailed moulding, e.g. of skin surfaces.
Paste-like, spreadable silicone that vulcanises at room temperature and can also be used for vertical work. Exceptional non-stick properties. Very suitable for special effects. RTV EC22 moulds can be filled with many materials, e.g. plaster, wax and synthetic resins. Several castings are possible with one mould. Talcum powder can be used as a release agent.
APPLICATION:
Weigh component A (pink) and component B (white) precisely in different containers and stir carefully and thoroughly in equal proportions by weight (100:100) to form a homogeneously coloured mass. Ensure that no residues remain in the weighing containers - a deviation from the mixing ratio of more than 5 % can change the vulcanisation. Process the silicone compound immediately after mixing.
The silicone cures at room temperature. Changing the room temperature can shorten or lengthen the processing time, while also changing the curing time: at 40 °C, the processing time and curing time are roughly halved; at 4 °C, the processing time is doubled and the curing time is approximately three times longer - in relation to the processing and curing time at a room temperature of 23 °C.
If skin surfaces are to be moulded with the silicone, apply Vaseline beforehand if necessary to protect fine hairs.
