What to do if molding silicone appears to be cured...

1. Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to    provide a significant shelf-life for the silicone rubber, we will dry out the water in the silicon rubber.     Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it. 2. If making paltinum silicone molds for an orginal model, pls make sure that your original model haven't ever touched with condensation silicone rubber before. Because platinum is quite sensitive from tin element in Condensation silicone rubber.
