Thermocoat W is a water-based intumescent paint system providing fire resistance to structural steel and cast iron that may be applied by brush, roller or airless spray.
A compatible decorative overcoat system ensures the system will enhance the building’s architectural and design features.
Thermoguard Thermocoat W is a low-odour, water-based coating, making it user and environmentally friendly.
The range of topcoats are either water-based or 2010 compliant and safe to use in accordance with manufacturer’s instructions.
- Water based Intumescent for structural steel
- For 30 mins protection: 1 thick coat – 2.5kg 4 linear m, 5kg 8 linear m, 20kg 32 linear m – if in any doubt please contact us.
- For 60, 90 or 120 minutes protection: contact us for further advice specific to your project
How intumescent coatings work
The heat of a fire triggers a catalytic reaction, causing the expansion of an insulating char layer up to 50 times the paint thickness. This layer keeps the steel below its critical temperature, thus maintaining the structural integrity of the building.
