Sibetter Silicone XB-7 series is a kind of condensation cure silicone rubber with mixing ratio of 100:3, thus 3% catalyst would be sent together with the goods and free of charge.  

Sibetter Silicone XB-6 series is a kind of platinum cure silicone with mixing ratio of 1:1. 






Why is the surface of the finished silicone mould unsmooth and figured

There maybe three reasons for this:

1. It is because the surface of the mother mould itself is not perfect;

2. the mother mould has not been grinded or polished before the further operation

3. the release agent has not been sprayed on the surface of the mother mould evenly

So when we make silicon moulds, firstly we should choose a prefect mold and polish it, then spray the release agent evenly on the product. In this case, the problem can be avoided.
