FIRE TEST PERFORMANCE
Tested to BS476 Part 20 (1987), showing that it can offer protection to structural steel for up to 90 minutes, and it has been tested when applied over multiple layers of existing paint, achieving protection of 150 minutes.
Tested to BS476 Part 22 (1987) on aluminium with Granada Windows, achieving 38 minutes of fire protection and again on aluminium with Wessex Medical lifts, achieving 49 minutes of fire protection.
Unprotected steel can lead to building construction collapsing in a fire.
It can take just a few minutes for unprotected steelwork in a building to attain temperatures of around 550ºC in a fire. At this temperature, steelwork loses its load bearing capacity and the structure is likely to collapse, giving little time for people to evacuate and even less time for the fire service to bring the fire under control.
Building regulations and legislation demand fire protection to upgrade the fire resistance of buildings and the Envirograf® range of intumescent coatings can certainly stand the heat. As modern design often involves steel being expressed as an architectural feature, intumescent coatings are frequently the protection of choice.
EP/FS/INT offers up to and including 90 minutes of fire protection and can be applied both on and off site.
EP/FS/INT is a waterborne product with low odour, often chosen as the ideal solution for on-site application. A full range of top sealers, both waterborne and solvent based are also available to complement the intumescent coating.
