The ultimate High-Gloss surface primer for wood, MDF, tooling board and composite plugs, patterns and models. Unique air-cure technology for fast cure even with thin coats. Easy to sand, polish to a gloss.  Take a mold directly off the Surface Primer or topcoat for the highest gloss.

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 micorns, 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.

 Duratec Vinyl Ester Primer is used for composite yacht priming and to provide protection against blistering and osmosis damage.

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.
