The product LAITEX ME-10 is a natural rubber-based compound specially prepared for occlusion-free mould interiors with perfect reproducibility. Once the LAITEX ME-10 is dry, an elastic and resistant mould is obtained; the thicker the surface, the more resistant it is.
Total solids: 59% ± 1,0 – Method I-10-31
Clean the surface of the object to be reproduced thoroughly to avoid imperfections in the mould, making sure that it is completely dry at the time of use.
Fill the work tank slowly, so as not to foam the ME-10; let it rest so that the occluded air rises to the surface and can be eliminated.
Then slowly introduce the original (cleaned of dust and grease) into the ME-10; depending on the time it remains immersed, we will obtain a greater or lesser thickness of ME-10.
Dry, without demoulding, at room temperature or in an oven at 70-80°C, making sure that the heat is not direct.
If you want to speed up the drying process, we suggest applying a thin layer, drying until the fingers still leave a mark, and repeating this operation successively until the desired thickness is achieved.
The ME-10 is perfectly dry when its colour changes from white to caramel. Then remove from the mould.
Due to its extraordinary elasticity, especially in thin layers, we recommend making a plaster counter-mould so that the ME-10 mould does not deform during the reproduction process.
While in the dipping process, the latex film is formed on the outside of the mould, in the casting process the latex film is formed on the inside of the mould.
Normally, hollow moulds of 2 or more parts made of porous material such as unglazed porcelain or plaster are used, which have a funnel-like opening through which the latex mixture is poured into the mould. In some cases it will be necessary to preheat them.
Once the product is inside the mould, a film forms on the inside wall of the mould by filtration of the serum, which thickens over time.
When the desired wall thickness has been reached, the remaining latex mixture, still liquid, is forced out through the opening.
The closed mould is left to stand until it is completely dry.
