préparation de la surface avant application préparation au jet de sable avant application

  • All parts of an object to be protected must be accessible for inspection, surface preparation, application of the zinc-rich coating and controlling its quality.
  • The surface of the object to be prepared for the application of a zinc-rich coating must be free of burrs, sharp edges (radius less than 0.3 mm), weld spatter, weld bulges, burns and flux residues. The welding sites of the metal framework (structural angles, plates, etc.) must not have inaccessible holes and cavities. If oil, grease, and other contaminants are on the surface, wash it off with detergents.
  • New steel (rolled stock) with scale adhering to the primer should be sanded to level SA 2.5 and degreased.
  • Degrease new steel (rolled broth) without scale.
  • Old rusty surface – loose rust is removed by hand or mechanically with scrapers, brushes, etc.) or with fresh water at high pressure at 10-20 МРа, followed by degreasing of the surface.
  • Zinc-plated preliminary surface – contamination and the top layer of zinc salts are removed by hand or mechanically (high pressure water at 10-20 МРа), followed by degreasing of the surface.
  • Previously painted surface – the paint is removed chemically and by washing (by hand or mechanically or with water under very high pressure 175-275 МPа), followed by degreasing of the surface.
  • The steps to be followed to obtain an anticorrosion coating based on the Zinker coating include the following sequence of six operations;
  • It is recommended to maintain the workflow of the anti-corrosion coating at an ambient temperature not lower than -30° С.;
  • To carry out anti-corrosion protection operations in winter, the following conditions must be fulfilled;
  • Provide awnings or shields from the elements;
  • The temperature of the metal surface should not be 3° C lower than the dew point temperature.

table-drawing-application

  • A simple application process allows the Zinker rust inhibitor to be spread well.
  • Zinker can be applied with a brush, roller or spray gun or also electrostatically, but in general it is simply applied with spray guns, like regular paint.
  • It is ready to use and can be easily applied by any painting method at any temperature (-30 ° C to + 50 ° C), humidity and even on rust.
  • Zinker is used to protect metal structures, in all types of corrosive environments, including aggressive and very aggressive (C5 according to ISO 12944-5: 2018), offering a guaranteed protection period * of 15 years or more with a thickness 120 micron layer
    *Soumis aux règles d’application
  • Zinker, rather hot-dip galvanized, is used to protect large products, hollow parts, but also thin-walled or welded elements.

Apply with a brush

The brush should be with natural bristles and free of dust and other contaminants. It is not necessary to dilute the zinc-rich coating with a solvent under standard conditions.

Apply with a roller

The roller should be made of a material resistant to organic solvents and free from previously used contaminants and MPVs. It is not necessary to dilute the zinc-rich coating with a solvent under standard conditions.

Application with a compressed air gun

Equipment should be free of previously used contaminants and MPVs. If necessary, a zinc-rich coating is diluted with “Zinker”, solvent or xylene at 5% by weight.

Airless spray application

Equipment should be free of previously used contaminants and MPVs. If necessary, dilute the zinc-rich coating with “Zinker”, solvent or xylene at 4% by weight.

Dip application method

If necessary, dilute the zinc-rich coating with “Zinker”, solvent or xylene to 15% by weight.

Application with an aerosol container

  • When applying the composition, hold the container vertically with the valve facing upwards, 25-35 cm from the surface to be protected. Apply at an ambient temperature of + 5 ° С to + 40 ° С.
  • When the job is done, clean the valve: Turn the receiver over and press the nozzle until the clean gas is evacuated. Remove composition residues with a swab soaked in “Zinker Multisolv”, solvent or xylene.
  • The material is applied layer by layer, overlapping the edge of the previously applied coating strip.
  • The total coating thickness should be a minimum of 40 mµ and a maximum of 160 mµ. When applying to constructions with slight mechanical deformation, the maximum thickness can be increased up to 200 mµ. Perform published work on the application of a zinc-rich coating (except when using an aerosol container) at -30 ° С to + 50 ° С and relative humidity up to 90%.
  • The composition can be applied to a wet surface. In this case, the surface must be free of water droplets. When applying at sub-zero temperatures, check for an ice crust. It is recommended to provide a canopy when applying in snow or rain conditions).

We recommend applying at least 80 microns, so one kilogram to cover 2 m2 , for increased and very long-lasting protection in very corrosive environments.

The pot life is unlimited when storage conditions are optimal, and the lid is properly closed. Polymerization of the coating occurs due to the evaporation of the solvent; therefore, if the lid is securely closed, evaporation and therefore polymerization does not occur.

  • Do not use on aluminum, copper and other non-ferrous metals.
  • Do not use over an already applied coat of paint.
  • Do not mix the product with the paint.
  • Do not use with or on bituminous, oily, petroleum products or with certain organic solvents: The coating is not resistant to petrol and several other organic solvents; therefore, it should be covered with a medium strength topcoat.
  • You should know that Zinker was developed by researchers in Russia, a country where winter temperatures are at least as low as those in Canada.
    The protection of steel in this part of the world faces the same constraints that we face in Canada.
  • You should know that Zinker can effectively replace your need for hot-dip galvanizing. It is a fast and high-quality solution, which allows you to meet the delivery deadlines of your projects.
  • Be aware that the use of widely answered epoxy solutions only produces a barrier effect but does not give you any cathodic (electrochemical) protection against corrosion. It suffices for the epoxy film to be pierced in one place by a bad application in one place, by the fall of a tool or brushing during handling, for corrosion to occur and it is deployed through your steel. , without you knowing it. We see this all too often happening in installations where steel is in contact with water and chemicals, for example. When you realize it, it might be too late for your steel.
  • You should know that it is not only the amount of pure Zinc that makes the effectiveness, but there are also zinc-based products that do not provide the necessary electrochemical protection, because they do not have the right combination of purity. with the shape of the particles and the suitable polymer.
  • You should know that almost all the products available on the market in America, do not allow you to carry out your steel repairs in negative temperatures. With Zinker, you increase the operational time window and you can carry out your projects with complete peace of mind.
  • Note that most products on the market must be used quickly once the can is opened, whereas Zinker has an unlimited pot life.
