Epoxy primer

  • Corrosion protective
  • Low-temperature curing
  • 2-component
  • Solvent-borne
  • Primer

Modified epoxy primer, fast curing with amine adduct, two component, cured in low temperatures (from -10°C).

For priming of steel constructions, thermally sprayed steel, aluminium or galvanized operating in sea, coastal and industrial environment. For priming steel and cast iron constructions operating in immersion. Can be applied on wet and not well cleaned surfaces. The coating cures very fast even in low temperatures. The paint is not moisture sensitive during curing. The coating is not sensitive to water (rain) when cured to touch dry degree. Flexible coating, with good adhesion to surfaces and resistant to mechanical factors. The coating resistant to weathering, water, salt and alkali solutions, oil, fuel oil, diesel, motor gasoline and some organic solvents. The coating is resistant to elements occurring in the cathodic protection.

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. The surfaces are prepared according to the different materials as follows: STEEL SURFACES: cleaned to the degree of cleanliness according to ISO 8501-1: at least Sa 2 for constructions operating in immersion and in aggressive environment, when long term protection is needed; at least St 3 for constructions used in industrial environment; at least St 2 for constructions used in atmospheric conditions and for internal surfaces. Dry, salt-, grease-, dust- and poor attached rust-free surface. It is possible to use on wet surfaces. STEEL SURFACES PREVIOUSLY PRIMED USING SHOPPRIMER: dry and free of contamination. Rust, mechanical, thermal damage or any defects of surface should be cleaned to at least Sa 2 according to ISO 8501-1 for immersion and St 3 for surfaces in atmospheric conditions. For internal surfaces St 2 is acceptable. Shopprimed coating without visible defects, roughened mechanically. NO STABILIZED HOT DIP GALVANIZED STEEL SURFACES AND DRY ALUMINUM SURFACES: should be tarnish with non-metallic abrasive. All contamination e.g. oil, grease, fluxing agent, etc. should be removed. Galvanized surface should be contaminant-free. STABILIZED HOT DIP GALVANIZED STEEL SURFACES: should be zinc corrosion products free (white rust free) and any contaminant-free. For cleaning hot water, water under pressure, steam, abrasives or manual mechanic tool cleaning can be used. The surface for painting should be dry, dust-, grease- and salt-free. THERMALLY SPRAYED GALVANIZED AND ALUMINUM SURFACES: should be dry and primed immediately with thin layer of diluted EPIRUST 2002 or EPIRUST, before any condensation occurs. The surface for painting should be dry, dust-, grease- and salt-free. Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.


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. Mixing by machine is recommended, for example a slow-rotating hand-drill equipped with a mixer. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties. Apply by airless spray or brush. When painting on wet or corroded surfaces it is recommended to apply first layer by brush. Airless spray parameter: Nozzle size 0.015 - 0.019". Nozzle pressure 15 - 20 MPa When preparing painting specification, depending on subject and type of construction, different dry film thickness than recommended can be assumed. During airless spray application typical dry film thickness range is between 35 and 90 µm. Different dry film thickness than recommended causes change in theoretical spreading rate, wet film thickness, weight of dry film thickness, drying time, overcoating time and ready for handling time. In high corrosive environment it is recommended to prepare surface as best as possible and to apply successive layers of paint before full curing of previous layers to achieve best protection. It is not recommended to apply EPIRUST 2002 on wet or covered with drops surfaces.

Application conditions

During the application and drying period the temperature of the ambient air shall be above -10°C, of the paint should be over +15°C and the relative air humidity below 95%. The minimum temperature of the surface shall be above -5°C (frost- and ice-free surface). The coating can be applied on wet and cold surfaces (temperature below dew point). The wet surfaces means: surfaces after hydroblasting or cold surfaces with temperature below dew point, without water observed. Adequate ventilation during application and drying period is recommended.
