Jotun Marathon 500 is a two component polyamine cured epoxy coating. It's a surface tolerant, high solids, high build product that will continue to cure even when immersed in water.

It can be used as primer, mid-coat, finish coat or as single coat system in atmospheric and immersed environments. Ideal for properly prepared carbon steel substrates.

Typical use

Jotun Marathon 500 is suitable for structural steel and piping to be exposed to corrosive environments up to very high and immersed.

Recommended for offshore environments, refineries, power plants, bridges, buildings, mining equipment and general structural steel. Specially suited in areas where high mechanical strength is required, such as splash or tidal zones. Compatible with cathodic protection systems.
