Jotamastic 90 AL

Aluminium flakes in this version of Jotamastic 90 create an impenetrable barrier to water and increased coating flexibility. The epoxy binds the coating together to give it considerable strength, particularly when applied to vulnerable areas. The aluminium range is particularly suited for submerged areas

Jotamastic 90 offers the longest lifetime in any environment. It has exceptional corrosion resistance, is fast drying - greatly improving efficiency, and is designed to be safely applied from 100 to 300 microns in a single coat over a wide temperature and humidity range.

Jotamastic 90 is surface tolerant and can be applied on surfaces that appear dry but where moisture remains and flash rusting has begun. It is ideal for use when blast cleaning is not possible.

Unlike the Standard version this product is only available in Aluminium colour.

Note:  The pack size (including hardener) is 4.55 litres and 20 litres nominal as the exact quantity of paint is colour dependent (the quantity of tint varies with each colour).

Use the AL (Aluminium flake) Wintergrade version for application below 10°C and faster curing times in normal conditions.

Recommended topcoats (above the waterline):

Standard: Conseal Touch-Up

Premium: Hardtop AX

Eco: Hardtop CA

Other topcoat options available. Please call us for advice.
