Jota Armour

 

Product description

Jota Armour is a three-pack, abrasion-resistant, high solids epoxy-based coating formulated to be applied in high film thickness for durability, wear resistant and anti-slip properties under dry, wet and oily conditions. The third component consists of selected blend of abrasion-resistant fused, aluminium oxides. The product is sold as kits and two kits are available, one with standard (Std) curing agent, and one with wintergrade (WG) curing agent.

    Surface preparation

     

    All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.

     

    Coated surfaces

    Clean, dry and undamaged compatible primer. Contact your local Jotun office for more information.

     

    Other surfaces

    The coating may be used on other substrates. Please contact your local Jotun office for more information.

    Condition during application

    The temperature of the substrate should be minimum +10°C (Std) (0°C in CC/WG) and at least 3°C above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Good ventilation is required in confined areas to ensure proper drying. The coating should not be exposed to oil, chemicals or mechanical stress until cured.

    Drying time

    Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:

  • Good ventilation (Outdoor exposure or free circulation of air)

  • Typical film thickness

  • One coat on top of inert substrate
