For the maximum recoat interval, refer to the Application Guide (AG) for this product.
The given drying and curing times are measured at 80% relative humidity during application and curing. Increased relative humidity accelerates curing; decreased relative humidity slows curing.
During the entire application, drying and curing period, the ambient temperature and relative humidity in the tank shall be strictly controlled. Touch-up work may be carried out immediately after completion of overall spraying; wet-on-wet application is preferred. It may also be carried out after the coating has fully cured; however, if zinc salts have formed on the surface, they shall be completely removed. For touch-up of cured coatings, 15% Jotun Thinner No. 25 shall be added.
Air circulation (moist air circulation) shall be provided to ensure all surfaces are properly exposed to a high-humidity environment.
To ensure proper curing, the relative humidity (RH) during curing shall be at least 60% (at 23 °C). At low temperatures, the relative humidity must be increased to ensure complete curing. Air circulation shall be provided to ensure all surfaces are properly exposed to a high-humidity atmosphere.
| 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. |
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.

For more resistance information, refer to the marine coatings resistance list and/or the protective coatings resistance list on the JOTUN website, or contact the local JOTUN office.
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.
To provide cargo resistance and durability, the following procedure shall be followed after the coating has cured to a serviceable condition:
- Spray seawater (not fresh water) onto the coating and keep the tank closed. Repeat water spraying 3–4 times within 48 h.
- Remove the water and allow the tank to dry.
- After the tank is completely dry, rinse with clean water if required.
- After completion of the procedure, the presence of white zinc salts will not adversely affect coating performance.

In some markets, the stated shelf life may be shortened to comply with local legal requirements. The above is the minimum shelf life; thereafter, testing is required to confirm quality remains acceptable.
For professional use only. Applicators and workers must be trained, experienced, capable and equipped to mix, stir and apply the coating correctly in accordance with JOTUN's technical documents. Applicators and workers must wear appropriate personal protective equipment when using this product. This guidance is provided based on current product knowledge. Any proposed modification to suit site conditions must be approved by the responsible JOTUN representative before use.
Read the safety warnings on the container packaging. Use in well-ventilated conditions. Avoid inhaling spray mist and avoid skin contact. 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.
