How it Works
When exposed to fire:-
- 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.
Fire Testing
- Product performance assessment based upon UKAS/EGOLF Fire Test Laboratory Certification to BS 476 Part 21 – Fire resistance to load bearing elements of structures.
Fire Certification
After use, a Certificate of Supply can be issued upon request for each specified project for insurance, Fire and Building Control Authority and Client Records.
