Antistatic Epoxy Tank Coating
PAINT TYPE
High solid epoxy paint, thixotropic, two component, cured with amines, containing
conductive pigments.
USAGE
For protection of inside linings of tanks, cisterns and piping installations for
flammable liquids, also in explosion hazard zones. For protection of inside linings
of tanks, cisterns and piping installations for liquid and loose products, which can
cause explosive mixture. For protection of laminate constructions and other nonconducting surfaces for its antielectrostatic finish.
SPECIAL PROPERTIES
Coating with outstanding adhesion to steel, laminates and mineral surfaces.
Coating resistant to mechanical factors, oil, fuel oil, heating oil, diesel, motor
gasoline, ethyl gasoline, unleaded petrol, biofuel, aviation fuel, glycol, glycerine,
aromatics, water, electrolyte solutions and weathering. Coating is antielectrostatic
conductive material according to PN-92/E-05200 and PN-92/E05203 standards.
With proper grounding the coating is unable to get electrified. Coatings surface
resistivity ρS is 106Ω, leakage resistance RU is 104Ω. Coating surface and surface
based on the coating fulfills requirements of protection against static electricity for
explosion hazard zones. Coating fulfils requirements according to TRbF 401
standards.

As many of the paint’s properties will change if too thick coats are applied, it is not
recommended that the product is applied to a film thickness that is more than
double of the thickest recommended film.
Practical spreading rate
The values depend on the application technique, surface conditions, overspray,
etc.

Before cleaning of surface, it is recommended to wash it with water with addition
of OLICLEAN 123 and then rinse with fresh water.
Steel surface dry, salt-, grease- and dust-free, cleaned to the degree of
cleanliness according to PN-ISO 8501-1, at least Sa 2½.
EPINOX®60 surface dry, rust-, salt-, grease- and dust-free.
Laminate surface contaminant-, dust-, grease- and oil-free. In case of old
laminates it is recommended to roughen it with abrasive paper (120-150).
Concrete surface fully cured (minimum 28 days at 20°C), rough, without cracks,
crevices and laitance, jet cleaned or cleaned using a wire brush. Surface must be
dry (relative humidity max. 4%), fat-, salt-, dust- and inclusions-free. Before
painting it is recommended to prime surface using varnish EPINOX 12 diluted with
TEKNOSOLV 564..
Mixing of the components
Take into consideration the pot life of the mixture when estimating the amount to
be mixed at a time. Before painting the base and hardener are mixed in right
proportions. Stir thoroughly down to the bottom of the vessel. Inadequate stirring
or incorrect mixing ratio results in imperfect curing and impaired film properties.
Application conditions
During the application and drying period the minimum temperature of the surface
shall be above +10°C at least 3°C above the dew point of the ambient air.
Minimum ambient air temperature +10°C. Maximum humidity 85%. Adequate
ventilation during application and drying.
Application
Airless spray, brush. When using a brush it may be necessary to apply several
layers to achieve recommended coating thickness
Airless spray parameter:
Nozzle size
0,48 - 0,63 mm
Nozzle pressure
20 - 30 MPa
Depending on application and type of construction, other thickness of a single
layer can be assumed instead of recommended. Typical dry film thickness range
using airless spray is from 150 to 300 µm. Changing the thickness of the coating
changes the theoretical consumption, thickness, weight of dry coating, drying
time, time of recoating and finishing work.
When using for antielectrostatic finish for non-conducting surfaces (laminates,
concrete), it is necessary to attach to surface earth electrode and cover it with
coating.
Laminate constructions (tanks, pipelines) where small abrasive and mechanical
hazard, should be painted with 1 or 2 layers giving in total dry film thickness 150200 µm.
Mineral surfaces (concrete floorings), where pedestrian and vehicular traffic takes
place, cover with 2 layers giving in total dry film thickness 300-400 microns.
ADDITIONAL INFORMATION
The storage stability is shown on the label. Store in cool place and in tightly
closed can.
Additional instructive information for surface preparation can be found in
standards EN ISO 12944-4 and ISO 8501-2.
