概览
关于Water-based intumescent coating
Applied like paint by airless spray, brush or roller over a compatible primer.
In a fire the coating expands into a thick insulating char that slows heating of the steel.
Thickness is set per member from the section factor, the critical temperature and the required rating.
主要优势
- Slim, architectural finish – the shape of the steel stays visible
- Low VOC and low odour for occupied buildings
- Can be applied in the shop, so steel arrives protected
- Decorative topcoat in any colour

我们如何在钢结构建筑中使用Water-based intumescent coating
World Steel can apply the primer and intumescent coating in our blasting and painting shop, so members arrive at site already fire-protected – thickness per member from the fire engineer's schedule, recorded in the coating report.
- 01与结构一同选型 – 厚度、密度和饰面与屋面、墙面及防火设计相匹配。
- 02工程量取自与钢构件、檩条和围护板相同的 3D 模型。
- 03与钢结构包一同包装发运 – 一份到场交货计划。
应用
Water-based intumescent coating的应用场合
- Exposed steel in atriums, lobbies and façades behind glass
- Office, retail and education buildings
- Car parks with suitable topcoat
