Easy Spray-On – Easy Release for Molds
PVA, or polyvinyl alcohol, should be used with our #1016 Partall Wax for the easy release of parts from a mold. Wax should be applied to the mold, 3–4 layers thick, and buffed to a high gloss. Once the final layer of wax has dried, PVA should be applied with the following considerations:
- PVA can be brushed on, but for best results, apply with a spray gun, 12–18 inches away from substrate.
- Generally, apply in three layers: the first, a thin mist, allowing 10-15 minutes to dry completely. Then apply two heavier flow coats, allowing each to dry completely (30-45 minutes each).
- PVA should form a smooth, glossy surface that will not shrink or pull away from corners or curved surfaces.
- It may be applied over polyester repairs, or gel coat, as a surface layer for airless tack-free cure.
As a dry film, PVA is resistant to the solvents in a resin system, but is water soluble. PLEASE NOTE: It should not be used with resin or substrate that contains—or produces—water during cure.
One gallon covers approximately 400 square feet.
