Applications where air-
cured chemistry and thin
film cure is d
esired.
The Duratec Pattern Surfacing Coating is a self- leveling, air cured polyester
coating. The rapid complete cure will provide a hard glossy surface for patterns
and molds. This exceptional product is easy to sand and polish, achieving a final
gloss over 90 percent. The Pattern Surfacing Coating will not dull during the
mold making process, thereby providing a superior surface over tooling gelcoat.
FEATURES
AIR CURE
Provides a complete cure, even at
10 mils, 250 microns.
RESISTS FISHEYES
Unique additives reduce the risk
of fish eyes and pinholes during
the spray application.
SUPERIOR FINISH
Porosity free coating produces
glossy patterns that retain 98% of
their initial gloss after mold
making process.
LABOR SAVINGS
Smooth surface minimizes
sanding. Patterns can be finished
the day after the pattern coating is
applied. Mold prep is also
abbreviated due to high gloss
transfer.

Prepare & Catalyze
Temperature should be at least 64 F for both the product and the part.
Mix with either a paint shaker or a drill-mounted mixer. A paint stir stick will not be enough for a proper mix.
For pattern or part
preparation, sand with 220 grit. Wipe down with a rag wetted with acetone. Do not use a
tack rag, as many tack rags will transfer materials to the surface. Seek a dust-free area around the pattern to
reduce contamination while the Duratec is liquid.
Catalyze the Duratec at 2.0 % by weight with a full strength MEKP, like Norox 925. Mix only an amount that can
be sprayed in 15 minutes. Mix well.
Additional solvent is not needed for most spray guns. If solvent is required, Duratec Reducer 39UCE-3 is the best
choice. MEK solvent is a good second choice. Discuss other options with our Technical Team prior to use.
If extended gel time is needed, check out Duratec Gel Time Extender.
Apply
Pattern Surfacing Coating should be applied by spraying. We recommend HVLP air-assisted spray guns.
A 1.8 mm tip is recommended. Use 34-40 psi air pressure (at the gun). Adjust the needle and fan to provide
the proper spray. Use the lowest pressures possible to minimize orange peel.
The first coat should be a light dust coat. The dust coating does not completely cover the surface. Wait at least
two minutes, and apply another light coat. Continue to make build passes of 4-5 mils, with two minute
intervals, until at least 20 mils of product is on the surface.
Apply build coats before the previous coat has tacked-off. The coating should be wet enough to transfer to a
fingertip. If the previous coat has cured enough that it will not transfer then allow for full cure and sand before
continuing.
Allow to cure fully. Sand and wait at least eight hours before polishing.

TROUBLESHOOTING | PRODUCT #902-046
Problem Cause Solution
Alligatoring
Not enough catalyst used.
Substrate/primer incompatibility or
chemical reaction.
Check for proper catalyst levels.
Expose surface to higher temperature
before spraying when ambient temp
is below 64 F, 18 C.
Product sprayed on cold surface.
Check compatibility of surface of product.
Cracking Product sprayed too thickly, too fast.
Increase the number of passes,
adding dwell time between coats.
Dimples (Craters)
Film build up too rapid, solvent
trapped in product.
Increase the number of passes to achieve
desired thickness. Allow for ash o
between passes.
Fisheyes
Substrate contaminated.
Do not use a tack rag . Ensure rag does
not leave contaminant on surface.
Spray in a clean area to minimize airborne
dust, water, waxes, and/or silicones.
Spray with dry fltered air.
Contamination in the air.
Contamination in the line.
Orange Peel
Spray equipment set up incorrectly.
Spray pressure incorrect.
Pot pressure incorrect.
Follow the instructions for equipment
set up.
Set pressure at 34-40 psi.
Set pressure at 10-12 psi.
Pattern surface
sticks to mold
upon release
Pinholes
Porosity
Improper release preparation.
Follow manufacturer s instructions
when applying release materials.
Primer not fully cured before
compounding and polishing.
Excess gel time for tooling gel coat.
Substrate porosity.
Fill porous areas with product using
squeegee, brush or roller before spraying.
Follow instructions in the application
guide for pattern surfacing.
Follow manufacturer s recs for gel time
Acetone used as thinner.
Spray pressure too high.
Spray orifce too small.
Reduce pressure to 34-40 psi.
Use larger orifce.
Use slower solvent such as MEK or
Duratec Reducer
