BURN BARRIER™ No. 50-69C and No. 50-69CX Cementitious Thermal Claddings
contain no asbestos. They are formulated essentially out of fire inert inorganic materials;
therefore, coated surfaces will not support combustion and are fire safe. No. 50-69C and
No. 50-69CX offer an inexpensive way of affording permanent, lightweight, fire protection
to interior and exterior structural steel. They are supplied as dry materials that are mixed
with water prior to application. These mixtures form a heavy slurry, that can be spray or
trowel applied. They do not employ the use of any flammable solvents; therefore, no fire
hazard exists during application and curing. The cured materials are noncombustible and
they import a high degree of thermal insulation.
No. 50-69C and No. 50-69CX exhibit excellent bond strength to primed and unprimed
steel. No. 50-69C is designed primarily for interior application, while No. 50-69CX is used
for exterior application.Fire Protection Properties:

Peoples Republic of China, Standard GN15-82:
Structural Steel L = 6300 X H = 400 X W = 200 mm, thickness 10mm, Weighing 71
*80 percent of actual time to failure. Time to failure 8.4 hours.
Mixing: (*) Use plaster/fireproofing mixer. For spray, add a maximum of 55 lbs. of water/50 lb.
Application: Can be trowel applied or sprayed. For spray application, use only equipment designed for
Maintenance Repairs: can be made easily by hand, using a trowel.
