Jotamastic 80 E
It is a two-component, polyamine-cured surface-tolerant epoxy coating. The product fully complies with LEED requirements and contains no solvents listed on the hazardous air pollutants (HAPs) list. It is a product with high surface tolerance and high solids content. Specifically designed for areas where ideal surface preparation cannot or need not be achieved. It can be used as a primer, intermediate coat, topcoat or single-coat system in atmospheric and immersed environments. Suitable for suitably prepared carbon steel and aged painted surfaces.
General:
Used mainly for maintenance and touch-up. Only aluminium-containing grades may be used in immersed environments.
Marine coatings:
Hull shell, exterior and interior areas.
Industrial protective coatings:
Recommended for offshore environments such as refineries, power stations, bridges, buildings, mining equipment and general structural steel.

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 service: the minimum time before the coating can be permanently exposed to a specific environment/medium.
| Paint temperature | 23 °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.

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.
