JOTUN JOTAMASTIC SF

Jotun Jotamastic SF is a two-component solvent-free polyamine-cured epoxy mastic coating.

Jotun Jotamastic SF is a two-component, solvent-free epoxy mastic coating cured with polyamine. Designed for maintenance and repair situations where ideal surface preparation isn’t possible, it provides durable protection in highly corrosive environments. This surface-tolerant coating adheres well to properly prepared steel, aluminum, and concrete. Moreover, it functions effectively as a primer, mid-coat, finish, or single-coat system for use both above and below the waterline. It works particularly well for maintenance on external hulls, interior and exterior structures, offshore areas including splash zones, as well as in refineries, bridges, buildings, and general structural steel.

Additionally, Jotamastic offers flexible and efficient application solutions for everything from small, high-performance touch-ups to large-scale maintenance jobs. It remains robust and reliable, even when applied using a variety of methods or in unpredictable conditions. Furthermore, it features short overcoating intervals and fast curing times, allowing for quicker project turnaround.

You can use it as a primer, mid-coat, finish, or as a single-coat system in both atmospheric and submerged environments. It is best suited for properly prepared carbon steel and aged coating surfaces.
