Jotamastic 90 Aluminium
This is a two-component, polyamine-cured surface-tolerant epoxy coating. It is a high-build product featuring surface tolerance, wear resistance and high solids content. It contains aluminium pigment, which improves protective performance. It is intended for areas where ideal surface preparation cannot be achieved or is not required. It provides long-term anticorrosive protection in highly corrosive environments. It may be used as primer, intermediate coat, topcoat or single-coat system in atmospheric and immersion environments. Suitable for suitably prepared carbon steel, galvanized steel, stainless steel, aluminium, concrete and many aged coated surfaces. Can be applied at substrate temperatures below 0°C.
General:
Mainly for maintenance and repair.
Marine coatings:

Regardless of substrate temperature, the minimum temperature of the mixed base and curing agent is 10 °C. At lower temperatures, thinner is required to achieve the specified application viscosity. Adding more thinner may reduce sag resistance and slow curing. If thinner is required, add it after mixing the two components.

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.
