Fireproof honeycomb panel is dedicated to a special fire-retardant paint by spraying special material to the aluminum honeycomb or steel honeycomb surface. When the cellular grid with thin coating is exposed to fire or temperature reaches 149ºC, retardant coating will react quickly and expand to fill the openings with carbon foams, preventing flame from spreading through the honeycomb panel.
With fireproof capability together with original EMI shielding, ventilation functions, this type of vent panel becomes essential to critical applications, such as telecommunication network equipment, server, harsh condition equipment, etc.
Aging test: 168 hours under 85 degrees, paint color get a little gray, combustion experiments showed that expansion properties of the coating does not change.
Constant temperature and humidity test: 85 degrees, 85% humidity for 168 hours, combustion experiments showed expansion properties of the coating does not change.
