Tufcote™ 3.5 PR™
High Solids Alkyd Primer
GENERAL
DESCRIPTION
An acrylic modified medium oil, lead and chromate free, single-package, 3.5 lbs/gal VOC
conforming primer based on Axalta alkyd technology. The resulting primer is designed to be
very quick drying and to deliver good corrosion resistance.
SUGGESTED USES
As a primer, direct-to-metal (DTM) or “shopcoat” on carbon steel and wood where:
 Universal primer for use under lacquer or enamel topcoats is needed
 Corrosion protection during transport and construction is required
 Fast dry and handling times may improve productivity
 Indefinite pot life, single component and no thinning is desired
 Rusted, hand or power-tool cleaned surfaces must be protected
 Using a coating manufactured from recycled products to support a commitment to reduce
environmental impact
COMPATIBILITY WITH OTHER COATINGS
As a universal primer, most topcoats can be applied over Tufcote 3.5 PR, including alkyds,
epoxies, polyurethanes, and acrylics. Testing for lifting, bubbling and adhesion is
recommended to assure compatibility with unknown coatings. Contact your Axalta
representative for specific recommendations.
NOT RECOMMENDED FOR
 Immersion service
 Application over galvanized steel
 Application over inorganic zinc
 Application by roller

Reduction
No further reduction necessary. Any thinning will increase VOC above 3.5 lbs./gal. VOC.
APPLICATION THINNERS
None required.
POT LIFE
Not applicable.
APPLICATION
SURFACE PREPARATION
Commercial Blast SSPC-SP 6 is recommended. If not possible, clean to an SSPC-SP 2
Hand Tool Clean or SSPCSP 3 Power Tool Clean with some sacrifice in performance.
APPLICATION CONDITIONS
Do not apply if material, substrate or ambient temperature is below 40°F (4°C) or above
110°F (43°C). For best results, the temperature should be between 65°F (13°C) and 85°F
(29°C). The substrate must be at least 5°F (3°C) above the dew point. Relative humidity
should be below 90%.
ROLL APPLICATION
Manufacturer: Wooster® Pro/Doo-Z ¼” - ½" nap
 Keep roll wet. Roll in one direction, rewet, then cross roll.
BRUSH APPLICATION
Manufacturer: Wooster China Bristle - 2”-4” brush
