ZINGALU is a one component high performance stand alone organic zinc rich coating. ZINGALU has 90% of

ultra pure zinc (ASTM D520 type III) and 4% aluminium flakes in the dry film which provide long lasting cathodic

protection to ferrous metals. The aluminium flakes offer barrier protection and a bright finishing color, matching

the color of galvanised surfaces. Therefore ZINGALU is ideal for repairing and touching-up of damaged or old

hot-dipped, Zinganised or other zinc coated structures.It can be applied by brush, roller or spray equipment on a

clean and rough substrate in a wide range of atmospheric circumstances.

    surface prepa ration

    Cleanliness - The metal substrate should first be degreased, preferably by steam-cleaning

    at 140 bar at 80ÅãC. After that it should be grit-blasted or slurryblasted

    to cleanliness degree SA 2,5 according to the standard ISO

    8501-1:2007 or to the cleanliness degree as described in the standards

    SSPC-SP10 and NACE nr 2. This means that the surface must be free from

    rust, grease, oil, paint, salt, dirt, mill scale and other contaminants. Once the

    blasting is completed the surface should be de-dusted with non contaminated

    compressed air according to the standard ISO 8502-3 (max

    quantity 2)

    - Another method to obtain a clean surface is UHP water-jetting to cleanliness

    degree SSPC-WJ2. But keep in mind that this method does not

    create surface roughness.

    - This high degree of cleanliness is also needed when ZINGALU is applied on

    a hot-dip galvanisation or a metallisation layer, or when it is applied on top of

    an existing ZINGALU layer, but not the same roughness degree (see further).

    Please consult with the Zingametall representative.

    - ZINGALU can be applied on light flash rust occurring (after wet blasting) in

    the allowed time limit, but it is not advised for optimal results.

    - On small areas or on non-critical applications ZINGALU can be applied on a

    surface that is manually prepared to degree St 2 according to ISO 8501-1.

    - For more information on surface cleanliness, please contact Zingametall.

    Roughness - It is recommended to apply ZINGALU on a metal substrate that has a

    roughness grade of medium G according to the standard ISO 8503-4:2012.

    - Make sure that the surface is degreased before the blasting.

    - This high degree of roughness is not needed when ZINGALU is applied on

    a hot-dip galvanisation or a metallisation layer, or when it is applied on top of

    an existing ZINGALU. Old hot-dipped surfaces have adequate roughness,

    new hot-dipped surfaces require a sweep blast or adequate power tool



    Maximum time to application Apply the ZINGALU as soon as possible onto the prepared metal substrate

    (it is recommended to apply before flash rust appears). If contamination occurs

    before coating, the surface must be cleaned again as described above
