FEATURES
EASY TO APPLY
The ability to be sprayed,
brushed, or rolled on makes for
easy application.
QUICK SHAPING
Q
uickly shaped by knife, file or
sandpaper.
RAPID BUILD UP
B
uilds quickly between 1 to
3mm, 40- 120 mils, maximum wet-
on-wet application with minimum
sag on vertical surfaces.
FAIR AIR CURI NG
Saves time and labor. The primer
quickly air cures to an easily sandable surface, which provides a stable base for other coatings.
PROTECTIVE LAYER
Hi-build primer offers a 200 F
HDT, which reduces the risk of post-cure distortion due to
exotherm and consequential print –
through of substrates.

The following use instructions are broad to address multiple applications. We recommend testing for product
compatability with your process. Please contact our Tech Team at (909) 546-1160 with any questions.
PLEASE NOTE
Catalyze
Catalyze with full strength MEKP Catalyst at 2% by weight (approx. 20 cc per quart). Norox 925 is a
good choice. Catalyze only what will be used in 10-15 minutes. Mix well.
Apply
Duratec Base
Primer is best applied by spray using an HVLP gun, or with a gelcoat application
system. Seek a fine spray, and use the lowest pressure that allows an even spray fan.
(approximately 40 psi). A 2.0 mm tip is recommended. If applying by brush or roller, please speak
with our Technical Support Team
Apply at least 10 mils, building 4-5 mils at a time, for even and complete cure. Recoat before the primer
has set up and lost its tack. If the primer cures completely wait at least eight hours, sand, and recoat.
Additional solvent is not needed for most spray guns. If solvent is required, do not add acetone.
Duratec Reducer 39UCE-3 is the best choice. Methyl Ethyl Ketone Solvent (MEK) will work for most users.
High quality urethane reducers are good choices. Lacquer Thinners are not recommended.
If extended gel time is needed, check out Duratec Gel Time Extender.
Sand
Sand when the primer has cured. The grit of sandpaper that should be used will be determined by the
surface quality of cured primer and your desired outcome.

TROUBLESHOOTING | PRODUCT #707-051Problem 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.
Primer sprayed on cold surface.
Check compatibility of surface of product.
Blisters
Substrate not cured, gassing
underneath primer.
Completely cure putties, pastes and
compounds before applying primer.
Cracking Primer spray too thickly, too fast.
Increase the number of passes, adding dwell time between coats.
Dimples (Craters)
Film build up too rapid, solvent trapped in primer.
Increase the number of passes to achieve desired thickness. Allow for ash o between passes.
Fisheyes
Substrate contaminated.
Do not use a tack rag , slow evaporating solvent.
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 35-50 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.

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 35-50 psi.
Use larger orifce.
Use slower solvent such as MEK or
Duratec Reducer
