Why silicone mold appear to stick to the hands?

Mold is mainly used in manufacturing products in large quantities. According to the materials, the mold can be divided into paper mold, metal mold, silicone mold, etc. Paper mold can be used only once, and silicone mold has high duplication times which has an effect of anti-sticking itself. In practical process, why silicone mold appear to stick to the hands? It may be some detail problems we didn't pay attention to in the process of making silicone mold.   The main reason for the sticky of the silicone mold is that the mixing ratio is inexact not weigh on the electronic scales or following the standard, and the mixture of silicone rubber and curing agent is not mixed completely and evenly. For example, the molding silicone rubber belongs to condensation silicone rubber which gets solidified after absorbing moisture from the air. If the humidity is relatively high, the silicone mold will appear to be dry outside but wet inside. Conversely, if the humidity is relatively low, so the moisture inside the silicone rubber will get more, external parts will slow drying, which also will lead to the problem of sticky of the silicone mold. This phenomenon does not belong to product quality problems, as long as you add or reduce the amount of curing agent according to the specific situation in this mixing ratio when using silicone rubber and stir them evenly.     Secondly, the factor for the sticky of the silicone mold may be that the original model is not perfect, and it has not been polished and cleaned. For this situation, you should handle this original model carefully before making silicone mold. Such as for the model with an unsmoothed surface or a complicated pattern, you should manually polish and smooth it and spray the release agent which can be liquid wax, detergent, Vaseline, etc. according to different material of model.   Thirdly, why silicone mold appear to stick to the hands can be due to the reason of incomplete vulcanization or improper operating temperature or curing temperature. You should pay attention to control the temperature in the process of operation and maintenance, it is best to use a thermometer. You also need to lengthen the curing time. Usually, the curing time is 3-5hrs at room temperature 25℃.   Of course, please don't overlook the importance of selecting a suitable and high quality silicone rubber.
