Water-soluble barrier coat between model and addition-cure silicone
PVA release agent is a solution of polyvinyl alcohol. Once the solvent has evaporated, a very thin, water-soluble layer of polyvinyl alcohol remains that seals the model. This often lets you use addition-cure silicones on a surface that would otherwise disturb the cure. It also stops silicone oil from soaking into natural stone and leaving stains. After demoulding you simply wash the layer off with water.
⚠️ Always test first
A PVA layer reduces the risk of inhibition of addition-cure (platinum) silicones, but it is no guarantee. Always test on a small area of your model or substrate first. With natural stone, also check that the layer can be removed completely with water afterwards.
Key benefits
- Sealing layer: often makes addition-cure silicones possible on an inhibiting surface.
- Water-soluble: easy to remove with water after demoulding.
- Protects natural stone: prevents stains from silicone oil.
- Simple: quick and easy to apply.
Typical applications
- ✓ Sealing models that may inhibit addition-cure silicones
- ✓ Moulding natural stone without silicone oil stains
Processing
- Apply the product thinly but with full coverage to the surface.
- Avoid applying several coats on top of each other: a new coat can dissolve the coat already applied.
- Let the solvent evaporate completely. Drying time depends on temperature and humidity.
- Then pour or brush on the silicone.
- Wash the PVA layer off with water after demoulding.
Points to note
- ✓ The product is flammable. Keep it away from flames, fire and hot objects.
- ✓ Work in a well-ventilated room and wear gloves.
- ✓ In case of eye contact, rinse immediately with water for several minutes. See a doctor if irritation persists.
- ✓ Keeps for at least 1 year when tightly closed and stored dark and cool (but not cold).
