Jotun Jotamastic SF Alu WG is a two component winter grade polyamine cured epoxy mastic coating. It is a surface tolerant, solvent free, high build product. This product is the winter grade version of Jotun Jotamastic SF Alu to aid application in lower temperatures (from 5 °C) and to provide faster drying and curing times.
This version of Jotun Jotamastic SF WG is aluminium pigmented for improved barrier effect. It is well suited for early immersion and specially designed for areas where optimum surface preparation is not possible or desired.
Jotun Jotamastic SF Alu WG provides long lasting protection in environments with high corrosivity and can be used as primer, mid coat, finish coat or as single coat system in atmospheric and immersed environments. Suitable for properly prepared carbon steel and aged coating surfaces.
Primarily designed for maintenance and repair for general use. It can also be used in marine environments for outside hulls, exterior and interior areas, including water ballast tanks. Suitable for water ballast tanks at newbuilding stage.
Jotun Jotamastic SF Alu WG is recommended as a protective coating for offshore environments, including splash zones, refineries, power plants, bridges, buildings, mining equipment and general structural steel.
Additional certificates and approvals may be available on request.

The temperatures listed relate to retention of protective properties. Aesthetic properties may suffer at these temperatures.
Note that the coating will be resistant to various immersion temperatures depending on the specific chemical and whether immersion is constant or intermittent. Heat resistance is influenced by the total coating system. If used as part of a system, ensure all coatings in the system have similar heat resistance
Depending on the actual exposure of the coating system, various primers and topcoats can be used in combination with this product. Some examples are shown below.
