Jotun Steelmaster 900WF Intumescent Paint

Jotun Steelmaster 900WF is a new product designed to bridge the gap between the very popular 600WF and 1200WF. Initially designed to be the go-to product for 90-minute fire resistance steel projects, it has since proven to be just as useful on some 60-minute and 120-minute projects.

900WF uses an enhanced waterborne acrylic thin film intumescent coating, making it suitable for use in C1, C2 and C3 internal environments. It has a shelf life of up to 12 months in a sealed container. Store according to the storage guidance in the technical data sheet, which you can find in the tab above.

Fire Testing

900WF has been tested in accordance with BS 476 part 20/21 and EN13381-9. Furthermore, it has been Certifire approved – document CF 6140.

It is suitable for use on structural steel which is exposed to cellulosic fire.

Primers and Topcoats

900WF cannot be applied onto raw steel. It must be applied onto a compatible primer. If your steel is bare, we recommend using Jotun Pilot QD primer beforehand. On galvanised steel, apply the Jotun Penguard Primer onto your steel beforehand.

As with all intumescent paints for steel, this product achieves a white matt finish. In C1 environments, the intumescent paint can be left without a topcoat if this colour finish is fine.

In C2 environments, or C1 environments where a colour finish is required, the Jotun Conseal topcoat should be used.

In C3 environments, we recommend using the Hardtop XP topcoat. lease contact us for a quote with your desired RAL or BS Colour code.

When needing topcoats, please contact us for a quote with your desired RAL or BS Colour code. The topcoats which can be purchased on our website come in stock white.

Application

900WF is easy to apply through brush and airless spray pump to give a good aesthetic finish. Ensure that you apply the product in a well-ventilated environment, which is at least 5 °C. Ideally, the application environment should be at least 10 °C.

Please refer to the application instructions in the data sheets tab above for more information.
