      Description 

      Two component protective zinc-rich epoxy primer.

      Filds of application

      EPPEX Zn primer is a cold-dip galvanizing material combining low consumption and high level of ferrous metal structures protection. It can be used in various thicknesses from 15 to 120 microns. It can be used as a shop primer in a layer of 15-20 microns. It is used to protect against corrosion products and structures made of ferrous metals, operated in atmospheric conditions, in water-saline mist conditions, in vapors and aerosols of petroleum products environment.

      It can be used  both as an independent coating and as a primer layer in complex protection systems. When self-coating, it is used without a finishing layer when painting objects exposed to atmospheric conditions (atmospheric corrosion category C3). In anti-corrosion systems it is used as a primer layer in combination with EPPEX primer and/or with polyurethane two-component enamel "Polytex".

      Due to its properties, the primer is used to protect construction metal structures, bridges and hydraulic facilities, ports and ship structures, overpasses and platforms, surface and vessel equipment, various tanks, storage facilities, pipes and pipelines, oil and gas pipelines as well as in the construction of railway and, in particular, sea and river transport.

      The primer coating does not prevent welding operations by spot welding or arc welding in an inert gas in the layer of 15-20 microns. The coating is resistant to sea and fresh waters, salts water solutions, oil and petroleum products.

      Information on the material resistance to various media is available on request.

      Main fields of application: transport construction, tank equipment, oil and gas industry, power engineering, mechanical engineering.

      Instruction for use

      Metal surface should be abrasive blasted to grade 1 due to GOST 9.402
      (Sa 2,5 to ISO 8501-1:2007) with roughness, recommended blast profile  is Rz=30÷50 mcm. Cleaned surface must be free of dust and grease. Application on a smooth surface without roughening is not allowed! 

      Conditions

      Ambient temperature from  +5°С  to +35°C.
      Relative air humidity no more 80%.

      The process of applying


      Preparation The product is two component. Component А is a dispersion of pigments and anticorrosion filler in epoxy resin.  Component B is a hardener solution. Mix the contents of the containers in the supplied proportions. After mixing, use within the specified pot life.

      Mixing sequence:
      The basis (component A) is mixed with a construction mixer. Then mixed hardener (component B) is added to the basis (component A) and thoroughly mixed with a construction mixer.

      Attention! Careless mixing or incorrect ratio can lead to uneven curing and painting film properties weakening.

      Minimum open time before coating materials are applied (at a temperature of (20+2)°C and relative humidity (65±5)%) is 3 hours.
      Maximum open time before applying the coating layers is no more than 1 year. Open time of the coating before use in aggressive environments is at least 7 days.
      Open time and cross linking depend on the film thickness, temperature, air humidity and ventilation.
