Application Guide
PARTALL@ Hi-Temp WAx
PARTALL@ Hi-Temp Wax is a premium multi-release mold release agent formulated from a blend of hydrocarbon and mlcrocrystal-
line waxes and fortified with PTFE polymer. lt is particularly recommended for use with epoxiesorphenolicsormpartofmdd
ingprocessesthatcureand/orcatalyzeathighertemperatures (150-350’F(65- L77 “C)) when castingcomposites partsor
molds from plugs. PARTALL@ Hi-Temp Wax may be used with most thermoset resins at ambient or elevated temperature cure,
and is especially useful in applications where standard silicone waxes hinder post-finishing operations. PARTALL@ Hi-Iemp Wax
has a creamy texture that makes for ease of application.

Fitm #1-O or PARTALL@ Coverall Film in conjunction with PARTALL@ Hi-Temp Wax to initialize new or reconditioned
polyester or vinylester molds, or on molds that are particularly intricate or too expensive to risk demolding problems.
PREPARING THE MOLD SURFACE
Molding surface must be thoroughly dry and free of other parting agents and contaminants such as silicone, dust, and compres-
sor oil prior to application of PARTALL@ Hi-Temp Wax. Porous molds (i.e., plaster or wood) must be sealed; composites grade
sealers, such as FORMULA FIVE
o Mold Sealer and FORMULA FIVE
o
Mold Sealer-S, are recommended but fairing compounds,
automobile type primer-sealers, and lacquers may be sufficient. Best practice is to allow residual solvents to out-gas from seal-
ers and waxes for at least one hour after application.
DIRECTIONS FOR USE
Use in a well-ventilated area with appropriate personal protection. Use a clean dry cloth or applicator pad to apply a thin even
coat of PARTALL@ Hi-Temp Wax to mold surface; 0.5-1.0 gm is sufficient to cover approximately 1yd2 (1 mz;. lf buffing by hand,
apply to a small section and begin buffing within one minute of application; it may be advantageous to have a second operator
follow to polish. A power buffer equipped with a terry cloth or lamb’s wool pad will reduce labor time on larger molds. Keep
power buffer moving constantly so as not to allow build-up of friction that could burn through the wax coating. Surface should
be buffed to a glossy finish.
Complete coverage is more imporlantthan wax film thickness. ln order to insure complete coverage, repeat application and
polishing process at least three times when initializing new or reconditioned molds or plugs. Alternate rubbing motions during
application of each coat (i.e., up-down, left-right, circular) and polish each coat before applying the next. Apply one coat of
PARTALL@ Hi-Temp Wax following each cycle thereafter until mold is broken in. Re-wax mold as necessary throughout produc-
tion. Allow at least one hour after application of final coat for residual solvents to out-gas before applying polyvinyl alcohol
(PVA) coating or casting parts.
The best procedure for separating parts from a mold depends on the size and shape of the part. ln most cases a part can be
lifted from the mold after loosening around the edges. On large curved parts it may be necessary to first tap over the surface
