Epoxy primer

  • Corrosion protective
  • Low-temperature curing
  • Wear resistant
  • 2-component
  • Solvent-borne
  • Intermediate
  • 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 and aluminium operating in sea, coastal and industrial environment. Can be applied on wet and not well cleaned surfaces. The coating cures very fast even in low temperatures. 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.

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: The surface to be treated must be dry, salt-, grease-, dust- and poor attached rust-free cleaned to the degree of cleanliness according to PN-ISO 8501-1: at least St 3 for constructions used in industrial environment; St 2 for constructions used in atmospheric conditions and for internal surfaces. It is possible to use on wet surfaces. STEEL SURFACES PREVIOUSLY PRIMED USING SHOPPRIMER: The surface to be treated must be dry and without any contamination (grease-, salt-, dust-free). Rust, mechanical, thermal damage or any defects of surface should be cleaned to Sa 2 according to PN-ISO 8501-1 for immersion and St 3 for external exposure. For internal surfaces cleanliness at least St 2. Surfaces covered with epoxy shopprimer without visible defects, abrasive blasted (submerged surfaces) or roughened mechanically (external surfaces). DRY ALUMINIUM SURFACES: The surface to be treated must be dry, tarnished with non-metallic abrasive, grease-, salt- and dust-free. THERMALLY SPRAYED ALUMINIUM SURFACES: The surface to be treated must be dry, grease-, salt-, dust-free and without other contaminants, primed immediately with thin layer of diluted EPIRUST 2012, EPIRUST 2002, EPIRUST or shopprimer, before any condensation occurs. 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 using a brush it may be necessary to apply several layers to achieve recommended coating thickness. 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 50 and 150 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 2012 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 and the relative air humidity below 95%. The minimum temperature of the surface shall be above -5°C (frost- and ice-free surface) and of the paint should be over +15°C. Adequate ventilation during application and drying period is recommended. 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.
