Phenolic Modified Primer
Phenolic modified medium oil, lead and chromate free, single-package, VOC conforming
primer (3.3 lbs./gal.) based on alkyd technology. The resulting very quick drying primer delivers good
As a primer, direct-to-metal (DTM) or “shopcoat” on carbon steel and wood where:
n primer for use under lacquer or enamel topcoats is needed.
n Corrosion protection during transport and construction is required.
n Fast dry and handling times will improve productivity.
n Indefinite pot life, single component and no thinning reduce cost.
n Application by brush, roll, or spray may be required.
n Rusted, hand or power-tool cleaned surfaces must be protected.
NOT RECOMMENDED FOR:
n Immersion service
n Application over galvanized steel
n Application over inorganic zinc
COMPATIBILITY WITH OTH COATINGS:
As a universal primer, most topcoats can be applied over HJ-0100, including alkyds, epoxies, polyurethanes,
and acrylics. Testing for lifting, bubbling and adhesion is recommended to assure compatibility with unknown coatings.
MAXIMUM SVICE TEMPATURE:
0°F (93°C) in continuous service
Chemical Very Good with appropriate topcoat

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. Steel surface should be clean, dry and free of any oil or
No activation required.
No further reduction necessary. Can be thinned up to 5% with HJ-O93D or HJ-612. However, thinning
greater than 5% will eliminate compliance with VOC limitation of 3.5 lbs/gal. See VOC chart.
Brush, Roll HJ-O94A
Normally no reduction should be required. See VOC information for amounts that can be added and still remain
compliant at 3.5 lbs/gal VOC.
CLEAN UP THINNS:
HJ-612 or mineral spirits
Do not apply if material, substrate or ambient temperature is below 40°F (4°C) or above 110°F (43°C). The substrate
must be at least 5°F (3°C) above the dew point. Relative humidity should be below 90%.
n Apply by brush, roll, or spray.
n Manufacturers listed below are a guide. Others may be used. Changes in pressure and tip size may be required
to achieve proper application.
