About this deal
the coverage will be reduced accordingly. The product may be applied in damp and humid conditions which is useful in ship and coastal applications. One of these oxides is magnetite [Fe 3O 4] or fersoferric oxide, a stable compound, which does not readily change as exposure conditions change. However, before doing this ensure that the previously applied coat is dry, particularly in the web/flange junctions
If a decorative finish is required, the product can be overcoated with Zeroflame Aquasteel WB+ Finish which has a wide range of colour options (RAL, BS & NCS)
Credit limit exceeded
It may be possible to apply two coats in one day, particularly if the atmospheric temperature is above 20°C and the relative humidity below 70%
Zeroflame Aquasteel WB+ is a white thin-film waterborne intumescent coating with a new and improved formula designed to provide 30 and 60 minutes fire resistance on standard structural steel members in internal environments. It provides an easier and more efficient alternative to cladding steel members in plasterboard.Chemical compound Freshly prepared aqua regia to remove metal salt deposits Freshly prepared aqua regia is colorless, but it turns orange within seconds. Here, fresh aqua regia has been added to these NMR tubes to remove all traces of organic material. Normally calculating the required material to achieve fire protection for structural steel involves the complicated and time consuming process of getting details of all the steel members involved in the project and calculating the exact amount of material required for each one.
