When our human body silicone rubber manufacturers are using silicone rubber, they must first confirm a few points when encountering the problem of skin color sticky silicone rubber:

　　1. Confirm whether the skin color human body silica gel used is fully cured. At room temperature of 25°C, there is 30 minutes of operation time, it takes 4 hours to fully cure. A friend explained that the silicone seems to be completely cured, but there is still a small part of it that sticks to your hands. This situation is caused by that small part of the human body silicone is evenly stirred, the A B components are according to the weight 1 :1 ratio for accurate ratio, resulting in part of the silicone is fully cured. In this case, there is no way to completely solidify that small part. It can only be scrapped a new mold needs to be made.

2. There is another situation that the mixing is even, it seems to be completely cured, there is still a small part of the viscosity similar to adhesive tape. If this happens, you must check the tools, materials molds. Addition type silica gel should be in contact with any other condensation type silica gel, otherwise it will cause silica gel ‘poisoning’ cause the silica gel to cure. Water, impurities, organotin catalysts, acids, alkalis other organic substances containing sulfur, phosphorus, nitrogen can affect the curing of the glue. Do mix contact these substances during use. During the experimental operation, production workers mold openers should smoke, otherwise it will be affected. Check whether these substances have been mixed during the operation?

3. Another point is to look at the hardness of the skin color of the human body silicone. First of all, we must know that the hardness of the silicone will also affect whether the silicone is sticky after curing. Generally, how much is the hardness of the silicone with a Shore A unit of 0 degrees even 5 degrees. It is always a bit sticky oily. Different manufacturers have different quality. Some manufacturers may have sticky silicone at 10 degrees. Of course, the engineers of Shenzhen Hongye Silicone Factory have solved this problem. The general solution is to apply talcum powder on the surface after the silicone is cured. This can solve the problem of the silicone sticking to the hands, use the heating curing method when the human body silicone is cured.
