- Exposure
- EAD 350402 type X or Y
- Durability
- Primer + intumescent + topcoat
- System
由 World Steel 随您的钢结构建筑一并供应或单独供应 – 一份订单、一次发运、一个合作伙伴。
概览
关于Exterior-grade intumescent systems
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.
主要优势
- Proven fire performance after weathering
- Protects exposed steel and canopies
- Works with ISO 12944 corrosion systems

FAQ
常见问题
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.
