 PARTALL Film #10 is a water and alcohol-based polyvinyl alcohol (PVA) coating comprised of water-soluble, film forming materials. The dry PVA film is resistant to the solvents in the resin system used to make composites parts but is soluble in water. It is particularly recommended as a parting agent for separation between polyester or epoxy resins and various mold surfaces but may be used with most thermoset resins. PARTALL Film #10 is not recommended for use with resin or substrates containing water or giving off water during cure. PARTALL Film #10 parts easily from mold surface and is readily dissolved from molded parts and spray equipment with water. For most composite casting processes PARTALL Film #10 is used over wax or other mold release agents. 


Directions for Use: 

 

PARTALL Film #10 is ready to use as received and should not be diluted. Preferred application is with a spraygun. Good results may be obtained with a sponge applicator or paint brush or by dipping substrate and draining excess PVA. Recommended air pressure with HVLP spraygun is 22 - 24 PSI (1.5 - 1.7 BAR) at the gun. When using a traditional spraygun adjust air pressure to 60 - 90 PSI (4 - 6 BAR). Normal gun to substrate spraying distance is 12 -18 inches (30 - 45 cm). On new or unseasoned polyester or vinylester molds, apply multiple coats of PARTALL Film #10 to surface and allow each coat to dry completely before proceeding. On seasoned mold, apply one or two coats of PARTALL Film #10. Do not begin molding until PVA on surface is completely dry. Drying time is approximately 15 - 30 minutes per coat depending on ambient temperature and humidity. On new or reconditioned molds dry film thickness should be at least 2 - 4 mils (50 - 100 micrometers), about the thickness of an industrial type trash bag. 1 - 2 mils (25 - 50 micrometers) is recommended on seasoned molds. PARTALL Film #10 will exhibit a white foamy appearance when sprayed but will dry to a clear coat. Film should not sag or contain runs when applied. If application flaws appear in PVA film wash off with water and begin again. Make certain that PARTALL Film #10 is completely dry before proceeding with molding process. Film should be very smooth and glossy when dry. A dull, hazy or grainy film may result from too thin a PVA film from insufficient spray - spray PVA to wet look. If spray air bubbles are trapped in PVA film try higher air pressure. One gallon (3.79 liters) covers about 400 feet(40 m).
