¡¡¡¡Antiflaming
mastic is made of pitch, mineral and other substances added
with adequate flame retardant. It has following features:  vapor stop, water impermeability, cold resistance, corrosion
protection, and not easy to deteriorate or crack. And it could
be used at normal temperature and could resist combustion after
dried. It is a kind of ideal coating material for cooling insulation,
fire proof and moisture resistance, which is suited for heat
insulation such as cellular glass and polyurethane in petrochemical
industry,etc.
Method of Application:
1.Smear
the mastic over the surface of cellular glass, no cryogenic
part or polyurethane, etc, with a layer of waterproof glass
cloth or plastic window gauze in the middle. And the thickness
is 3mm. Only after the first layer of mastic gets a bit dry,
the second can be smeared. The gross thickness reaches to 5mm
after drying. 2.Smear
evenly, and no foaming on the surface.
3.Use
Level: 12.5kg/m2 ( include the wastage).
Technical Data:
1. Flame Resistance: It causes no spark during construction,
has flame resistance after dried and extinguishes in 1s after
taken away from fire source.
2.Heat
Durability: There'll be no signs of flowing and foaming when
it is placed at 45o below the temperature of 95¡æ for 4 hours
and then at the temperature of 120¡æ for another 1 hour.
3.Water
Absorption: The water absorbed is less than 1% of its weight
after 24h' soaking at normal temperature.
4.Frost
Resistance: No crack occurs when it is suspended at -40¡æ and
60¡æ for 2h respectively.
5.Drying
Time: It can be touched with fingers after 1h, while it costs
60h to dry completely.
