- Interior / sheltered
- Exposure
Supplied by World Steel with your steel building or on its own – one order, one shipment, one partner.
Overview
About Solvent-based intumescent coating
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.
Key benefits
- 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

How we use Solvent-based intumescent coating in steel buildings
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.
- 01Specified with the structure – thickness, density and facing matched to the roof, wall and fire design.
- 02Quantities taken from the same 3D model as the steel, purlins and cladding.
- 03Packed and shipped with the steel package – one delivery schedule to site.
Applications
Where Solvent-based intumescent coating is used
- Shop-applied protection of beams and columns
- Warehouses, factories and logistics buildings with fire-rated steel
- Semi-exposed steel with approved topcoat
