    Glue-injected protective kits and fireproof coatings
    DS-202 cable fireproof coatings

    Product overview

    DS-202 cable fireproof coatings is a new type of fireproof coating successfully developed by our company according to the national standard of GA181-1998, which is composed of tertiary propylene emulsion waterborne material with various fire retardants, plasticizers, etc. It is a advanced waterborne fireproof coating for wire and cable in China at present. This product can generate uniform dense sponge foam insulation layer when the coating is subjected to fire, which can effectively inhibit and block the propagation and spread of flame, and play a protective role for wires and cables. Its main advantages are environmental protection, no pollution, non-toxic and tasteless, no threat to the health of the applicator. This product also has a thin coating, strong adhesion, good flexibility and other characteristics, and has good insulation, anti-corrosion function.


    Scope of application

    This product is widely used in the fire retardant treatment of wires and cables in power plants, industrial and mining, telecommunication and civil buildings, and can also be used in the fire protection of objects such as combustible substrates of wooden and metal structures buildings and underground projects.

    Construction method

    • Before the construction of fireproof coatings, the surface of the cable should be cleaned and polished of floating dust, oil, sundries, etc., and the construction of fireproof coatings can be carried out only after the surface is dry.
    • The construction of this product adopts spraying, brushing and other methods, the use of which should be fully stirred, and when the coating is a little thick, it can be diluted with appropriate amount of tap water to facilitate spraying.
    • During the construction process and before the coating is not dry, it should be waterproof, anti-exposure, anti-pollution, anti-movement, anti-bending, and if it is damaged, it should be repaired in time.
    • For plastic, rubber jacket wires and cables, directly paint for more than 5 times generally. The coating thickness is 0.5-1mm and the approximate dosage is 15Kg/m². For an insulated cable with oiled paper outside, it should be wrapped with a layer of glass cloth, and then painted. If the construction is carried out in the outdoor or humid environment, it should be added with matching cover varnish.
