Description
A water-based intumescent paint system providing fire resistance to structural steel and cast iron.
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.
Features and benefits:
- Available in pack sizes of 2.5 kg, 5 kg, 20 kg.
- Minimum 30 minutes fire resistance subject to manufacturer's guidelines.
- Low-odour, water-based coating, making it user and environmentally friendly.
