PVA, Partall #10, Green Liquid Release, 5 GL; traditional alcohol based

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 feet2 (40 m2 ).
