MORE INFO
Polyvinyl alcohol (PVA). Release agent, impregnation, pore filler, protection. Non-toxic, grease-free, water-soluble, washable.
PVA forms a thin release agent layer that has a separating and protective effect. Suitable as a protective and release agent for moulding master models when moulding with polyester, polyurethane or epoxy resin, as it is resistant to all solvents contained in these resins. Suitable for protecting or separating master models that have a non-solvent-resistant surface. Suitable for sealing porous surfaces and as a release agent, e.g. for master models made of wood or plaster, (dried or fired) clay or stone before moulding with silicone or other moulding compounds. Suitable for protecting casting moulds, e.g. made of silicone, which are to be filled with synthetic resins.
Release agent can be washed off with water, use a brush if necessary. Can be sanded off very porous surfaces if necessary.
Application:
Apply PVA in at least two coats: Brush the original model or casting mould carefully and evenly with a thin layer of PVA. Allow the release agent to dry to a solid layer within 20 - 30 minutes. Do not apply the second coat until the first coat is completely dry. Do not apply moulding compound or casting compound until the last layer of PVA has completely hardened.
