      Description

      Two component protective zinc-rich epoxy primer EPPEXZnRICH.

      Scope and specifics of application

      EPPEX Zn RICH primer is a cold-dip galvanizing material with a high volume dry residue, high zinc content and good protective properties. It is recommended for use as a primer in complex anti-corrosion protection systems with polyurethane two-component enamel "Polytex". It can be used without finishing coating when painting objects exposed to atmospheric conditions (atmospheric corrosion category C3).

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

      It is used for coating pipes and pipelines, oil and gas pipelines, railway bridges, road bridges, tunnels, ground parts of piles, overpass supports, road fences, navigation and vehicle control facilities as well as for coating steel structures and equipment in the wood and chemical industries.

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

      Main applications: oil and gas industry, transport construction, chemical industry.

      Instruction for use

      1. Metal surface must be degreased to grade1 due to GOST 9.402.
      2. Metal surface should be abrasive blasted to grade 2 due to GOST 9.402
      (Sa 2½ or Sa 2 по ISO 8501-1) with roughness, recommended blast profile  is Rz from 30 to 50 mcm. For hot-rolled steel, mechanized and manual surface cleaning up to degree 3 is allowed due to GOST 9.402 (St 3 or St 2 to ISO 8501-1).
      Application on a smooth surface without roughening is not allowed.
      3.Metal surface must be dust free.

      Conditions

      Basis temperature higher than dew point no less than 3°C.
      Ambient temperature from  -10°С  to +35°C, when applying at the temperature ≤00С surface icing is highly possible. Primer  temperature when applying should be no less than +15°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.
      The maximum time of cross linking time is 6 months. With a longer cross linking time, the coating must be sanded before applying the next layer
      Open time  and cross linking time depend on the film thickness, temperature, relative humidity and ventilation.

      Finishing
      Tubing, pistol and other spraying tools must be cleaned after using.
      Cleaning
      Wash the tools after using immediately. The frequency of washing depends on the amount of sprayed material, the temperature and the time since the shutdown, including any time lag.
