New fire classification Bfl s1 for FLOORTOP 1K determination of fire behavior using a radiant heat source
Dec 18, 2020
New fire classification Bfl s1 for FLOORTOP 1K determination of fire behavior using a radiant heat source. The painting system with FLOORTOP 1K has just obtained the fire classification Bfl s1, this classification consists of two tests:
The first test method determines the flammability of the construction product by direct application of a small flame, with zero radiation and using samples tested in vertical orientation.
Second, method to evaluate the behavior against fire and propagation of the horizontal flame in the opposite direction to the wind of covering floors exposed to a gradient of radiant heat flow in a test chamber, when burned with a pilot flame during a 30 minute period.
This solution is designed to offer Krypton Chemical systems greater resistance to degradation by UV radiation, its aliphatic polyurethane nature ensures color stability and offers greater resistance to wear.
Case study of the month: Roof waterproofing of a pharmaceutical factory in Egypt
The cover, with a mortar support, showed many infiltrations.
To solve the problem, an inexpensive and simple solution was applied in two simple stages. Primer Epoxy 100 and Impermax Polyurea H Flex membrane (aluminum color).
This special color is maintained over time and it is possible to avoid the aliphatic protective topcoat. Impermax Polyurea H Flex with a great ability to bridge cracks in the substrate (static class A5 and dynamic class B.4.2) presents an ETA certificate, a Broof(t2) class exterior fire behavior certificate and a hail resistance test, among others.
The photos show the difficulty of treating this roof, due to the large amount of equipment installed on top of it. In these extreme conditions, the applicator and the owner appreciated the simple and fast execution in two simple stages and with a 100% solvent-free system.
