In recent years, fires have occurred in many places, resulting in increased losses. In fact, during inspections, it was found that fake and inferior fire-retardant and flame-retardant decoration materials were used.


These include fire-retardant and flame-retardant coating products, which have almost no flame retardancy, while qualified tunnel fire-retardant coatings can be flame-retardant for more than ten minutes.

When the surface of the wood board coated with qualified tunnel fire retardant coating encounters fire, the tunnel fire retardant coating can rapidly foam and expand in a short time.

And form a uniform and dense honeycomb or sponge-like carbon foam layer to isolate the flame from the wood, prevent or delay burning,

So as to play a good role in protecting the combustible wood.


Under normal circumstances, qualified tunnel fire retardant coatings can be flame retardant for more than 15 minutes.

Unqualified tunnel fire retardant coatings do not foam or crack directly when exposed to fire because there is no flame retardant or very few flame retardants.

There will be a lot of scattered slag, and it is not flame retardant or has poor flame retardancy.


It is understood that the price of counterfeit tunnel fireproof materials and qualified tunnel fireproof materials is twice or even several times different.

While cracking down on the illegal activities of making and selling fakes, the fire department released a coup for identifying the authenticity of tunnel fireproof coatings:


1. Carefully check the packaging of the tunnel fire retardant coating to see if there are signs, manufacturer's name, factory address, and contact number on the packaging.

Qualified tunnel fireproof coatings are marked on the packaging; check whether the packaging barrel has been pryed,

Prevent the purchase of counterfeit tunnel fire retardant coatings in old barrels; check whether the handwriting on the package is clear, and the handwriting on the package of qualified tunnel fire retardant coatings is clear;


2. When purchasing tunnel fireproof coatings, check whether there is a qualified inspection report issued by the national fire protection quality inspection center.


3. Obtain samples for fire resistance test.

This editor reminds everyone to carry out strict inspections when installing tunnel fire retardant coatings to prevent unnecessary losses.
