Partall FILM #10 Technical Bulletin
GENERAL INFORMATION
Partall
?
Film #10 is a water/alcohol-based Polyvinyl Alcohol (PVA) solution of water-soluble, film
forming materials. It is particularly recommended as a parting agent for separation between
polyester or epoxy resins and various mold surfaces.
Partall
?
Film #10 is not recommended for
use with resins containing water or giving off water during cure (i.e., phenolics). or with automotive
finishes as damage may occur.
Partall
?
Film #10 will not shrink or pull away from corners or curved surfaces.
Film parts easily
from mold surface and is readily dissolved from molded parts and spray equipment
with water.
An occasional coating of Partall
?
Paste #2 is suggested for most mold surfaces prior to
application of Partall
?
Film #10.
PREPARATION OF MOLD SURFACE
Porous molds (i.e., plaster or wood) must first be sealed with lacquer or similar coating. A good
surface on plaster may be obtained with automobile type primer-sealers and lacquers. Mold
should be thoroughly dry and free of other parting agents. Cleaning with fine steel wool or sandpaper
will not affect the high gloss obtained with Partall
?
Film #10 although deep scratches or pits will fill with
s
olution and increase drying time.
APPLICATION OF PARTALL
FILM #10
Apply Partall
?
Paste #2 according to instructions prior to use of parting film. Partall
?
Film #10 is
ready to use as received and should not be diluted. Apply with a spray gun, adjusting air pressure
to approximately 90 psi at the gun. Normal spraying distance is 12 to 18 inches.
Apply a mist coat of Partall
?
Film #10 to mold surface followed by at least two flow coats. Allow
each coat to dry completely before proceeding (drying time is approximately 10-15 minutes for
mist coats and 30-45 minutes for flow coats). A spray density that just allows the liquid to flow
together and form a continuous film is ideal. Dry film thickness should be at least 2-4 mils (about
the thickness of an industrial-type trash bag) on new or reconditioned molds (1-2 mils on seasoned
molds). One gallon will cover about 400 square feet.
Factors such as humidity and proximity to direct sunlight may cause drying time to vary.
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 film may result from insufficient spray and may
contain pinholes.
REMOVING PART FROM MOLD
The best procedure for separating parts from a mold depends on the size and shape of the part.
In most cases a part can be lifted from the mold after loosening around the edges. A jet of air
between the part and mold at the edge is sometimes useful. On large curved parts it may be
necessary to first tap over the surface with a rubber mallet. A very strong blast of air, or a few
squirts with a CO
2
extinguisher, can aid in freeing very rigid parts that cannot be flexed.
