Zinc reach epoxy primer

  • Corrosion protective
  • Heat resistant
  • 2-component
  • Solvent-borne
  • Primer

A two component, fast curing, metallic, zinc rich epoxy primer cured with polyaminoamide

For priming of steel constructions operating in marine and industrial environment e.g. bridges, flyovers, pipelines, supporting structures etc. Coating with good mechanical properties and outstanding adhesion to the surfaces, resistant to corrosive factors of marine and industrial atmosphere and periodical influence of temperature up to 150°C. Not resistant to acid and alkali environment. Available in ASTM D520, type II zinc dust version as a standard. Zinc content in the dry coating min. 80%.

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- and dust-free, cleaned to the degree of cleanliness according to ISO 8501-1 at least Sa 2½. 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. Mix thoroughly components and wait 15 minutes (at 23°C) before use. After mixing the components, it is recommended to filter the mixture through the sieve mesh 900/cm². Apply by airless spray, air spray (with the use of guns with upper hopper or paint feeding from a separate hopper) or brush (in the case of corrections or small surfaces). It is necessary to mix the paint continuously during painting, due to settlement of the metallic pigment. Airless spray parameter: Nozzle size 0.43 - 0.53 mm Nozzle pressure 20 - 25 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 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. The compartment must be ventilated during and after painting as long as the odour is sensible.

Application conditions

During the application and drying period the temperature of the ambient air and the surface shall be above +10°C and the relative air humidity below 85%. 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 period is recommended.
