Antistatic Epoxy Tank Coating

»
  • Chemical resistant
  • Conductive (ESD)
  • Corrosion protective
  • 2-component
  • Solvent-borne
  • DTM (direct-to-metal)
  • Primer

High solid epoxy paint, thixotropic, two component, cured with amines, containing conductive pigments.

For the protection of inside linings of tanks, cisterns and pipelines for flammable liquids, also in explosion hazard zones. For protection of inside linings of tanks, cisterns and pipelines for liquid and loose products forming explosive mixtures. For protection of laminate constructions and other non-conducting surfaces for its antielectrostatic finish. 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. The surface resistance ρs of the coating is about 10exp.6 Ω, the leakage resistance Ru is about 10exp.4 Ω, measured according to EN 61340-2-3:2016-11. The coating of the paint, as well as the laminate based on it, meets the requirements of protection against static electricity related to hazardous areas. Coating is antielectrostatic conductive material, surface resistivity of the cured INERTA 266 coating is no more than 10exp.6 Ω. The coating meets the requirements of the standard TRbF 401.

Surface preparation

Before cleaning of surface, it is recommended to wash it with water with addition of OLICLEAN 123 and then rinse with fresh water. STEEL SURFACES: dry, salt-, grease- and dust-free, cleaned to the degree of cleanliness according to 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). Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.

Application

Take into consideration the pot life of the mixture when estimating the amount to be mixed at a time. Before application the base and hardener are mixed in right proportion. Stir thoroughly down to the bottom of the vessel. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties. When using a brush it may be necessary to apply several layers to achieve recommended coating thickness. Airless spray parameters: 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. 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 150-200 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.

Application conditions

During the application and drying period the temperature of the ambient air, the surface and the product shall be above +10°C and the relative air humidity below 80%. The temperature of the surface to be treated must be at least +3°C above the dew point of the ambient air. Adequate ventilation during application and drying. If application and drying is carried out at lower temperatures, a winter hardener should be used. Please contact your Teknos representative.

Storage

The storage stability is shown on the label. Store in a cool place and in tightly closed containers.
