Selection & Specification Data
Generic Type
Epoxy polyamide with corrosion inhibitor (zinc
phosphate)
Description
Versatile corrosion resistant coating. Used either
as a primer, intermediate coat, or self-priming
finish over steel and zinc primers. May be
topcoated with itself, or a broad variety of high
performance finish coats. Product also has
surface tolerant properties. Optional (LT) cure for
35°F cure capability.
Features
Ready to apply after mixing; no sweat-in time or
thinning required.
Economical fit for use epoxy
Available in a variety of rapid tint colors
Attractive low sheen for tank exteriors
Used as a primer, intermediate, or finish coat
Power tool cleaned surfaces acceptable
Optional low temperature (LT) cure Part B
VOC compliant to current AIM regulations
Colo
Primer color (0700) gray. Variety of other finish
coat colors in rapid tint service. Use Bright White
(T800) for tank exterior finish. See Limitations
when using (LT) cure.
Finish
Low sheen
Primers
Self-priming. May be applied over zinc rich
primers. A mist coat may be required to minimize
bubbling over inorganic zinc rich primers.
Topcoats
Acrylics, Alkyds, Epoxies, Polyurethanes
Dry Film
Thickness
3.0-5.0 mils (75-125 microns) per coat as a primer
or an intermediate. Two coats at 3-5 mils (75-125
microns) per coat may be used direct-to- metal.
4.0-6.0 mils (100-150 microns) per coat as a finish
coat over a primer. Do not exceed 10 mils (250
microns) in a single coat. Excessive film thickness
over inorganic zincs may increase damage during
shipping or erection.

Dry Temp.
Resistance
Continuous: 200°F (93°C)
Non-Continuous: 250°F (121°C)
Discoloration and loss of gloss is observed above
200°F (93°).
Limitations Epoxies lose gloss, discolor and eventually chalk
in sunlight exposure. LT Cure will cause additional
discoloration as it weathers and/or ages.
Substrates & Surface Preparation
General
Surfaces must be clean and dry. Employ
adequate methods to remove dirt, dust, oil and
all other contaminants that could interfere with
adhesion of the coating.
Steel
For most applications:
SSPC-SP6 to obtain a blast profile of 1.0-2.0
mils (25-50 microns). May also be applied over
SSPC-SP3 for certain applications.
Galvanizing
Galvanizing requires a roughened surface for
optimum adhesion/performance of high build
epoxies. Remove any contaminants per SSPC
SP1; ensure there are no chemical treatments
that may interfere with adhesion; and abrade the
surface to establish a suitable roughness
(typically 1 mil). SSPC-SP7 or SP11 are
acceptable methods.
Concrete
Concrete must be cured 28 days at 75°F (24°C)
and 50% relative humidity or equivalent. Prepare
surfaces in accordance with ASTM D4258
Surface Cleaning of Concrete and ASTM D4259
Abrading Concrete. Voids in concrete may
require surfacing.
