VR-500 SERIES AIR DRY PHENOLIC COATINGS
GENERIC TYPE:Air drying phenolic
RECOMMENDED
USAGE: Heresite VR-500 air dry phenolic series
coatings are specifically formulated to permit
application by brush, spray or roller. some of their
outstanding properties are excellent durability, good
adhesion, good film building characteristics and
flexibility.
When thoroughly aged they produce hard corrosion
resistant films. Recommended as a heavy duty maintenance
coating for exposures to splash, spillage and fumes.
Successful applications include: agricultural
implements, chemical plants, canning factories,
construction equipment, marine finishes, steel plants,
sewage disposal plants, textile industry, underground and
underwater service, and ventilating systems. The VR-514
brown coating is a primer-finish combination material,
specially formulated for salt water service.
When finished product is going to be
exposed to UV rays, one topcoat of Hersite UC-5500 is
recommended.

| COVERAGE: Theoretical
Coverage -- 737 sq. ft. per gal. at 1 mil. Recommended
dry film thickness is 4.0 to 6.0 mils in 2 to 3 coat
system. (At 5 mils DFT average coverage would be 118 sq.
ft. per gal. This includes a 20% loss factor.) |
| SURFACE PREPARATION: Remove all oil or grease from the surface with an
appropriate solvent, such as Heresite S-330. |
- STEEL:
- NON-IMMERSION: A commercial
blast is recommended in accordance with NACE #3
or SSPC-SP-6-63 specifications
- Surface profile or anchor pattern shall be 20 to
25% of the recommended dry film thickness.
|
- CONCRETE: Remove protrusions by
stoning, sanding or grinding. Concrete must be
cured at least 28 days at 70ºF(21°C) and 50%
relative humidity.
- NON-IMMERSION: Surfaces must be
acid-etched or abrasive blasted to remove
laitance.
|
PRIMER: While VR-500
Series are self-priming on steel, four primers are
available.
VR-502P, VR-504P, and VR-506P are inhibitive primers to
be used for maximum corrosion resistance.
VR0508P is a primer for use in food service areas, on
concrete or porous surfaces
On concrete or porous surfaces two (2) coats of primer
with two (2) coats of finish are recommended. The first
coat shall be thinned one (1) part primer to one (1) part
S-240 Solvent. |
| THINNER: Recommend use
of S-440 Solvent for spray application and S-240 Solvent
for brush or roller applications |
- THINNING: The type and amount of
thinner required is dependent upon temperature,
ventilation, humidity, spray equipment used, and
desired film thickness.
- SPRAY: All Heresite VR-500
Series coatings are normally diluted. VR-514 is
normally diluted five (5) parts coating to one
(1) part S-440 Solvent. Other VR-500 Series
coatings are normally diluted four(4) parts
coating to one (1) part S-440 Solvent.
- BRUSH OR ROLLER: (non-porous
surfaces)Heresite R-500 Series coatings may be
applied without dilution. If desired a small
amount of S-240 Solvent may be used.
|
APPLICATION:
- Do not apply if temperature is less than 5°F
(2°C) above dew point, or if temperature is
below 45°F(7°C).
- All spray equipment shall be thoroughly cleaned
and the hoses in particular shall be free of old
paint film and other contaminants.
- Use standard production type spray guns, such as:
| Guns |
Fluid |
Air |
| DeVilbiss
JGA-502 |
E |
704 |
| Binks #62 |
66-SS |
66-SS |
| Graco
P800 |
04 |
02 |
| May also be applied with
airless spray equipment. |
- Air supply shall be uncontaminated. Adjust air
pressure to approximately 50lbs. at the gun and
provide 14-20# pot pressure. Adjust spray gun by
first opening liquid valve and then adjust air
valve to give approximately an 8" to
12" fan, holding gun perpendicular to the
surface at a distance of 12".
- Apply a mist bonding pass.
- Allow to flash off for several minutes, but not
long enough to allow film to completely dry.
- Apply 2 to 4 criss-cross multi-passes maintaining
a wet appearing film. Approximately 2 to 4 mils
wet film thickness equals approximately 1.5 mils
dry film thickness.
- Air dry, with ventilation.
|
- CURING SCHEDULE:
- AIR DRY SCHEDULE:
6-8 hours per coat @ 70°F(21°C).
FORCE CURE SCHEDULE:
20 minutes per coat @ 250°F(121°C).
- CLEAN UP:
- Use Heresite S-440 Solvent
- STORAGE CONDITIONS:
- Coating should not be stored longer than 24
months. Storage at above 80°F(27°C) may shorten
shelf life.
