Covering fireproof for KEDR-MET-V air ducts
The thermodistending covering of "KEDR-MET-V" is intended for increase of fire resistance of designs of air ducts of forced-air and exhaust systems, all-exchange, emergency, antismoke ventilation, air conditioning systems, channels of technological ventilation. The covering is applied in the enclosed space of buildings and constructions of industrial and civil function in the range of temperatures from- 50ºС to +60ºС with relative humidity no more than 80%.
Advantages
Except the advantages listed for a covering for a metalwork of "KEDR-MET-K" , the covering of "KEDR-MET-V" possesses:
- high vibrostability;
- high adhesion to steel and galvanized surfaces.
Properties
"KEDR-MET-V" - water dispersible paint, ready to application. The created fireproof covering on the basis of KEDR-MET-V paint provides a limit of fire resistance of designs of steel air ducts of EI - 30 minutes (GOST P 53299).
