Description
AITHON A90H creates a hard, reflective char with high insulation properties which shows excellent adhesion to the concrete substrate even after 4 hours of fire exposure above 1150°C, despite the slab deflection (289 mm after 240 minutes, with 4250 mm spam between slab supports)
Tested
The BS EN 13381-3 regards the fire resistance of concrete structures and the performance of the intumescent coatings applied on concrete are expressed in terms of equivalent concrete thickness. The method defines the quantities (in gr/m2) of intumescent coating required to achieve the same insulation performance provided by different thicknesses of concrete. The calculation of the equivalent concrete thickness required for slabs and walls exposed to fire on one side is based on fire test results achieved on loaded slabs having minimum (500 gr/m2) and maximum (2035 gr/m2) applied quantity of intumescent coating. Linear interpolation between minimum and maximum is allowed.
