Marathon 1000 GF
This is a two-component polyamine-cured epoxy coating. Solvent-free, glass flake reinforced high-build product. It has very good impact and abrasion resistance. Suitable for highly corrosive environments such as splash zones and tidal zones. In atmospheric and immersion environments, it can be used as primer, intermediate coat, topcoat or single-coat system. Suitable for properly prepared carbon steel substrates.
Industrial protective coatings:
Suitable for steel structures and pipelines in highly corrosive and immersion 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.
Can be used together with anti-slip sand and topcoat in anti-slip deck systems.
Compatible with cathodic protection systems.
Others
Pre-qualified in the selected coating system in accordance with NORSOK M-501. Other certificates and approvals are available on request.

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.
| 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.
Dry/cured to service: the minimum time before the coating can be permanently exposed to a specific environment/medium.
| Paint temperature | 23 °C |
| Pot Life | 45 min |
Lowering the temperature prevents the paint from expanding.
Temperature
| Drying, atmospheric | Continuous 120 °C | Peak - |
| Immersed, sea water | 50 °C | 60 °C |
Withstands peak temperatures for a maximum of one hour.
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.
| Previous coat: | Epoxy, zinc-rich epoxy, inorganic zinc silicate |

In case of accidental splashes on skin, wash immediately with a suitable cleaner, soap and water. In case of eye contact, rinse thoroughly with water and seek medical attention immediately.
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.
The information in this datasheet is based entirely on knowledge gained in our laboratory and in practice. JOTUN products are regarded as semi-finished products, and their use is generally beyond our control. JOTUN therefore guarantees only the quality of the product itself.
