Marathon 500
It is a two-component polyamine-cured epoxy coating. It is a high-build product with surface tolerance and high solids content. It continues to cure when immersed in water and has good abrasion resistance. Suitable for highly corrosive environments, such as splash zones and tidal zones. It can be used as a primer, intermediate coat, topcoat or single-coat system in atmospheric and immersed environments. Suitable for properly prepared carbon steel, galvanised steel, stainless steel, aluminium and concrete substrates.
Suitable for steel structures and pipes in highly corrosive and immersed environments. Recommended for offshore environments such as refineries, power stations, bridges, buildings, mining equipment and general structural steel. Particularly suitable for areas requiring high mechanical strength, such as splash zones and tidal zones. Compatible with cathodic protection systems.

For the maximum recoat interval, refer to the Application Guide (AG) for this product.
Drying and curing times are determined based on temperature and relative humidity below 85%, with dry film thickness within the average range.
Excessive dry film thickness or over-thinning extends drying and curing times.
If applied one hour earlier on the tidal zone of legs and piers, the product may be immersed in water. Early immersion causes whitening, visible on most dark colours. However, corrosion performance is not affected.
| Touch Dry | The state at which light finger pressure leaves no mark or stickiness. |

| Walk-on Dry | The minimum time after which the coating allows normal foot traffic without leaving permanent footprints, marks or other physical damage. |
Minimum recoat interval after drying: the recommended minimum interval before applying the next coat.
Dry/cured to immersion: the minimum time before the coating can be permanently immersed in sea water.

At the above temperatures, protective performance is unaffected, but appearance may be affected.
Note: this coating can withstand different immersion temperatures, depending on the specific chemical and whether immersion is continuous or intermittent. Heat resistance is affected by the coating system as a whole. When used with other coatings, ensure that all coatings in the system have similar heat resistance.
Depending on the actual exposure conditions in service, this product may be used with various primers and topcoats. Some reference systems are listed below. For specific systems, contact JOTUN.

When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
