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.
For severe dry, wet and oily conditions requiring durability, wear resistance, anti-slip properties, such as flight decks, military applications, extreme environments. Approved to U.K. Defence Standard 80-134 for the Royal Navy. One-coat, high build application over anti-corrosive primer.

*Measured according to ISO 3233:1998 (E)
All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.
Clean, dry and undamaged compatible primer. Contact your local Jotun office for more information.
The coating may be used on other substrates. Please contact your local Jotun office for more information.
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.

The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.
