Jotacote Xtend GF
Two-component amine-cured abrasion-resistant epoxy glass flake coating. High solids content and low VOC content, with a mass proportion in the paint below 10%. General-purpose primer developed and designed specifically for severe environments requiring long-term corrosion protection design life. In atmospheric and immersion environments it can be used as primer, intermediate coat, topcoat or a single-coat system. Suitable for properly prepared carbon steel, stainless steel, aluminium, galvanized steel, concrete and thermal spray zinc substrates.
Suitable for steel structures and pipelines exposed to "very high" corrosivity categories or to immersion and buried environments. Recommended for offshore environments, including splash zones, refineries, power stations, bridges, buildings and mining equipment. Within a certain dry film range and on the coated areas, the product offers excellent flexibility. Specifically for areas requiring abrasion and impact resistance, such as decks, walkways and landing areas.

For the maximum recoat interval, refer to the Application Guide (AG) for this product.
Drying and curing times are measured at a dry film thickness of 300 µm under controlled temperature and relative humidity below 85%.
Extra care is required when overcoating at low temperatures; the whole coating system requires higher temperatures to cure and develop good mechanical strength.

| 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 service: the minimum time before the coating can be permanently exposed to a specific environment/medium.

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.
