Prepare & Catalyze
T
emperature 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 to mix up.
The primer should be sanded with 220 grit, and wiped down with an acetone damped rag. Do not use
tack clothes.
Catalyze the Duratec at 2.0 % by weight with a low hydrogen peroxide MEKP, like Norox 925H
Additional solvent is not needed for most spray guns. If thinning is required, we suggest the use of
Duratec 39UCE Reducer.
IN-MOLD USE: Vinyl Ester Hi-Gloss Topcoat can be sprayed in mold, but equipment and technique will need to be
adjusted in comparison to tooling gelcoat application in order to support the lower-viscosity Vinyl Ester Hi-Gloss
Topcoat. We suggest use of an HVLP gun over a dump-gun and use of wax mold release agent like TR108 or honey
wax rather than or in conjunction with semi-perm release agents. Wax allows the proper surface tension essential for
the product to level and flow across the in-mold surface. If you are experiencing severe fisheyes when applying in-
mold, it is likely the semi-perm release agent is preventing the necessary surface tension.
Apply
Duratec Vinyl Ester Hi-Gloss Topcoat should be applied by spraying. We recommend an
HVLP air-assisted spray
guns or with a gelcoat application system.
A 1.8 -2.2 mm tip is recommended (depending on part size). Use 34-40 psi air pressure (at the gun). Adjust
the needle and fan to provide the proper spray.
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. After two additional minutes, begin build coats of 4-5 per
pass, waiting 2 minutes or more between passes.
Apply at least 18 mils for an even and complete cure. Recoat before the topcoat has set up and lost it s tack.
If the topcoat cures completely, wait at least eight hours, sand, and recoat. Wait at least eight hours from the
start of sanding before polishing or topcoating.

TROUBLESHOOTING | PRODUCT #1904-045
Problem Cause Solution
Alligatoring
Not enough catalyst used.
Substrate/product 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.
Blisters
Substrate not cured, gassing
underneath product.
Completely cure putties, pastes and
compounds before applying 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
