Intumescent · exterior exposure
Exterior-grade intumescent systems
Steel outside the building envelope needs an intumescent system proven to keep its fire performance after weathering.
- Exterior / semi-exposed
- Exposure
- EAD 350402 type X or Y
- Durability
- Primer + intumescent + topcoat
- System
World Steel が鉄骨建築と一括で、または単体で供給 – 一つの注文、一つの出荷、一つのパートナー。
概要
Exterior-grade intumescent systemsについて
The European assessment document EAD 350402 classifies reactive coatings for durability: type X for all conditions including exterior, type Y for internal and semi-exposed, Z1 and Z2 for internal conditions; EN 16623 sets durability requirements as well.
Exterior systems are usually solvent-based or epoxy intumescents with a compatible sealer or topcoat; the whole system – primer, basecoat and topcoat – is what was tested.
Corrosion protection of the steel underneath follows ISO 12944 for the environment.
主なメリット
- Proven fire performance after weathering
- Protects exposed steel and canopies
- Works with ISO 12944 corrosion systems
- Shop or site application

FAQ
よくある質問
Can an interior intumescent be used outside with a topcoat?
Only if that complete system has been tested for exterior durability – otherwise choose an exterior-qualified system.
Is this product certified?
Certification belongs to a specific manufacturer’s product or tested system. We supply the test report, classification or listing accepted in your market for the product selected – it is confirmed per project, never assumed.
