Different profile types (open sections or hollow sections) have different heating behaviour. For example, hollow sections heat up faster than open sections (e.g. I sections, H sections) with the same U/A factor. Therefore, the coating thicknesses to be applied are…
In case of small gaps, it can be assumed that the insulation layer builder will bridge them in the event of a fire by foaming. The surface in the gap should be coated as deep as possible. For larger gaps,…
No maintenance is necessary. The top coat must be checked regularly to ensure that it is undamaged. Damage to the coating structure must be repaired professionally. The manufacturer's instructions must be observed. The owner of the object is responsible for…
We recommend first removing loose dust or other dirt by hand or mechanically, for example by blowing, vacuuming or lightly brushing. However, care should be taken to avoid damaging of the coating. Further cleaning procedures depend on the product and…
As mechanical damage is largely excluded, maintenance is only required if water damage occurs.
To obtain a building authority approval for exterior intumescent materials, outdoor exposure of coated steel plates is required. After 2, 5 and 10 years, aged plates are officially tested again and the approval is extended accordingly. If a top coat…
A general statement on this is not possible. The manufacturers provide information whether systems with or without topcoat are approved. Products specially developed for protection against hydrocarbon fires can even be used in adverse climatic conditions such as offshore structures.
Component temperature not below + 5°C, maximum + 40°C Relative air humidity max. 80 Dew point distance during processing and drying ≥ 3 K Protect the coating from weathering (rain) until the entire coating is finished and fully cured! Depending…
The required layer thickness depends on several factors. These include, among others: the section factor (U/A factor), the type of profile (closed/open), the exact fire scenario (cellulosic fire, hydrocarbon pool fire, hydrocarbon jet fire, etc.), the desired fire resistance duration,…
The section factor is defined as the ratio of the flamed circumference to the cross-sectional area of the profile. There are tables for the commonly used standardized profiles. Thin-walled profiles with a correspondingly large section factor heat up more quickly…
