Because liquid silicone molding base material is using vinyl triethoxy silane to advocate material, it is a platinum catalyst of curing agent, because platinum is heavy metal products, very temperamental, it is the most afraid of tin material, so as iron and other metal is easy to cause its not curing phenomenon. If it does not cured, it will appear that the surface is sticky, which is called intoxication or cannot be completely cured. If the platinum catalyst will react with our silicone, it will never cured.
In addition, if you want to use the molding silicone rubber, remember not to use it as a condensing silicone device to make the silicone products. If the mixture is used, it will be unsolidified.
