PVA release agent

PVA (polyvinyl alcohol) is a liquid release agent that creates a thin film over the surface. This film is very strong and resistant to many chemicals, including epoxy and polyester.

Applications

PVA release agent can be used for:

• Damaged moulds.
• Moulds with a poor surface.
• Substrates of unknown or unsuitable composition, such as porous or sanded substrates.
• Substrates that are not resistant to polyester.

Directions for use

Processing Polyvinyl alcohol is easy. You can simply apply the release agent with a brush or a moist sponge. When using polyvinyl alcohol, ensure that the entire surface is covered with alcohol. PVA release agent can also be applied with an air sprayer. In addition, you can dilute the PVA release agent with water or alcohol (methylated spirits). First spray a mist layer, and then a wet layer.

After application, the release agent will dry to a tough film layer in approximately 1 hour. When the release agent has dried, you can apply gelcoat, polyester or an epoxy product in the mould.

On porous substrates, we recommend applying the PVA in several layers until it has formed a dense film layer on the surface.

Unloading is easy. You add some lukewarm water which will make the Polyvinyl alcohol layer dissolve. The final product and the mould can be easily cleaned with water.
