概要
Solvent-based intumescent coatingについて
Dries faster than water-based coatings and tolerates higher humidity during application.
Suited to off-site application in the fabrication shop, followed by careful packing.
Topcoated for semi-exposed and humid interior areas.
主なメリット
- Fast drying – practical for shop application and tight schedules
- Better tolerance of humid climates during application
- Robust finish for transport and erection
- Thin film keeps steel slim and visible

鉄骨建築におけるSolvent-based intumescent coatingの活用
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構造と一体で仕様決定 – 厚さ、密度、表面材を屋根・外壁・耐火設計に合わせます。
- 02数量は鉄骨、母屋、外装材と同じ 3D モデルから算出。
- 03鉄骨パッケージとともに梱包・出荷 – 現場への納入スケジュールは一つです。
用途
Solvent-based intumescent coatingの用途
- Shop-applied protection of beams and columns
- Warehouses, factories and logistics buildings with fire-rated steel
- Semi-exposed steel with approved topcoat

FAQ
よくある質問
What thickness of solvent-based intumescent coating do I need?
It depends on the member size (section factor), the critical temperature and the required fire rating – the fire engineer or the manufacturer's tested data gives a thickness for each member.
Does World Steel supply branded products?
Yes – we supply the brand and listed system your specification or authority requires. This page describes the product type.
