You'll save time and labor and add quality with Duratec
Polyester Base Primer. Here's why you should choose Duratec Polyester Base
Primer-- Easy to apply -- apply with a sprayer, brush or roller. Rapid coat
buildup--builds quickly--between 1 to 3 mm, 40-120 mils, maximum weton-wet
application with minimum sag on vertical surfaces. Quick Shaping--quickly
shaped by knife, file or sandpaper. Fast air curing--saves time. The primer
quickly air cures to an easily sandable surface, which provides a stable base
for other coatings. High heat distortion temperature--reduces the risk of
post-cure or distortion from elevated temperature due to exotherm and
consequential print-through of substrates.
Usage For composites, metal, MDF, brick, concrete, various
lowdensity foams, plaster and clay.
Features:
Here's why you should choose Duratec Polyester Sanding
Primer: Low porosity--provides a super fine leveling and filling system on a
variety of substrates with superior release properties. Adhesion to most
epoxies -- with heat distortion level of 201°F, 94°C, the primer also adheres
to fiberglass, properly prepared metal, wood, MDF, brick, concrete and
polyurethane foam. Rapid coat buildup--to 40 mils, 1000 microns, wet on wet, on
composite plug and master mold surfaces; saves time and labor cost. Easy sanding--saves
time and effort. An exceptional primer for topcoating with Duratec Surfacing
Primers and HiGloss Coatings, lacquers and polyurethane paints.
Recommended Uses:
• Surface coat for plugs/ patterns for composite tooling.
• Easy Sanding High-Build Primer for composite parts.
• High Build, Fast Sanding Primer perfectly smooth surfaces
• A substitute for sanding gelcoat -epoxy laminates or
pinhole-free surfaces.
• Highly crosslinked coating providing excellent chemical
resistance Features: Low Porosity- provides a super fine leveling and filling
system. Applied properly, Surface Primer provides a porosity-free surface
without pinholes or defects. Adhesion to most epoxies- with heat distortion
level of 200° F/93 C the primer also adheres to fiberglass, wood, MDF, brick,
concrete and polyurethane foam. Rapid Buildup- up to 40 mils 1000 microns, wet
on wet, on composite plugs and master mold surfaces. Save time and labor. Easy
Sanding-also saves time and labor. The primer cures to a surface that polishes
to a gloss.

Important: If the surface to be coated is epoxy laminate—
• Always test the compatibility between the epoxy surface and Duratec products.
• Do not apply Duratec Vinyl Ester products over epoxy putties that contain microballoons.
• If the surface is epoxy resin or laminate, scrub with an abrasive pad and water to eliminate any possible amine blush that may be exposed due to sanding and might interfere with the adhesion of Duratec products to the epoxy substrate. Here’s how to apply Duratec Vinyl Ester Primer: 1. When Duratec Vinyl Ester Primer is applied over Duratec Vinyl Ester Fairing Putty or Duratec Vinyl Ester Fairing Primer, follow instructions outlined above. Otherwise, sand or sandblast the surface to a 80- or 120- grit finish and wipe with a fast solvent and clean white cloth. Do not use a tack rag. 2. Thoroughly stir Duratec Vinyl Ester Primer in the can. Catalyze at 2 percent with full strength mekP catalyst (20cc/quart) for an 18-20 minute pot life. If ambient temperatures are excessive, cool the primer to 77°F, 25°C to create a longer pot life. Thin, if necessary, 10-20 percent with Duratec Thinner or mek solvent after catalyzation.
Important:
• For proper blister/osmosis resistance, Duratec Vinyl Ester Primer must have a minimum of 0.5 mm, 20 mils, dry thickness remaining after sanding before topcoating. If the primer is used for cosmetic applications above the waterline, no minimum thickness is required.
• After sanding, allow the primer to cure overnight at 77°F, 25°C before topcoating. This allows for the release of solvents that may be trapped at the surface. Spray Application: 3. Gravity, siphon or pressure-pot spray systems can be used. Line air pressure should be between 35-50psi and pot pressure should be 12-15psi. A 1.5- 2.5mm diameter air-cap, needle and nozzle arrangement is recommended. (Plural-component spray equipment —airless, air-assist and/or air-aspirated.
