Polyvinyl Alcohol Release agent
Poly vinyl alcohol can be used to prevent cure inhibition from an otherwise "toxic" surface for addition curing silicones. If this poly vinyl alcohol is brushed on properly the poisoning material will not bleed through.
PVA dissolves readily in water making it is easy to rinse off with water. Even if you want to copy stone(work) without staining it with silicone oil you can put on a layer of PVA. This layer may later be washed off with water. Please always do a little test to see if this works in your specific situation.
- Easy and fast to work with
- Makes otherwise poisoning surfaces available to addition curing silicones
