5.0 Cable Fire retardant Coatings
Application scope: can be widely used in metallurgy, chemical, power and other industries of wire and cable fire protection coating. When there is a fire, it plays a fire and flame retardant, heat insulation expansion error effect to win the fire fighting time.
Fire prevention base: ductile elastic 5. 0 fire retardant coating is an intumescent fire retardant coating, the coating film will soften the bubble expansion and produce carbonified foam, the foam contains low thermal conductivity substances, can protect the material from damage due to high temperature, the heat insulation and flame retardant effect of the coating is remarkable.
The state in the container is the same as that in the container after stirring.

Oil resistance d
Foaming 7 days, coating no wrinkle, no fall, foaming in the standard environmental conditions for 24 hours of basic recovery, allowing slight discoloration and foaming for 3 days, coating days up and down, no thorns, foaming in the standard
Salt corrosion resistance d
Under environmental conditions, it can basically recover for 24 hours, allowing slight loss of light.
Moisture and heat resistance d
After 7 days of trial staining, the smear positive had no berthing and no shedding, and slight loss of light was allowed.
Freeze-thaw cycle resistance
After 15 cycles, there are no foaming and no detuber, and less than 2 lines are allowed to appear.
I bending resistance
If you can't spread an eagle, you don't want to fall, and you're allowed to have less than eight cracks.

In order to make the coating play a role in fire prevention, it is necessary to meet the requirements of the coating:
1. In the flammable substrate, not less than 1000g per square meter, to ensure the above dosage, can ensure that the refractory time in more than 30 minutes, to meet the first level requirements, generally coated three times, each interval of about 4 hours.
two。 Brush the surface of the power cable to ensure that the thickness of the coating is not lower than that of 1mm.
1. Construction method: manual brush with row brush, flat brush, sprayer can also be selected for spraying. The number of brush channels needs to be increased to reach the thickness.
two。 Construction preparation: remove dust and oil from the surface of the substrate. If it is spraying, it should also cover the parts that do not need to be sprayed, and the paint should be thoroughly stirred and evenly before construction.
3. Construction environment: under the condition of temperature 5-40 °C and relative humidity less than 90%, the construction should be carried out in an environment with temperature of 5-40 °C and relative humidity of less than 90%.
4. Note: the coating shall not be mixed with other paints and coatings in order to avoid affecting its fire prevention effect and construction under the condition of drying and ventilation.
Storage and transportation:
The coating should be stored at 5-40 °C.
