Intumescent coatings

intumescent coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material and retard the rapid spread of fire. It is used to increase the fire resistance of the coated material.

intumescent coatings are based on their flame-retardant mechanism:intumescent coatings can be divided into two types, intumescent intumescent coatings or non-intumescent intumescent coatings.

    Non-intumescent coatings are mainly coatings that are flame-resistant or non-combustible, and can release fire-extinguishing gases under flames or high temperatures to prevent or delay the coating from catching fire.

The intumescent intumescent coating is that its coating undergoes intumescent carbonization under flame or high temperature, forming a non-flammable sponge-like carbon layer that is tens or even hundreds of times thicker than the original film, in order to isolate the external flame from heating the substrate. At the same time, a large amount of non-combustible gas is generated during the coating film''''''''''''''''''''''''''''''''s melt expansion process, which dilutes the combustible gas generated by the thermal decomposition of the substrate, which can effectively prevent the spread of the flame, thereby achieving the role of protecting the substrate.

    Our products can be widely used in intumescent intumescent coatings. When the intumescent intumescent coating is heated, it acts as a strong dehydration carbon-forming catalyst, which dehydrates the carbon-forming agent into carbon while generating a large amount of non-existent gas to expand the coating. It is an indispensable part of intumescent coatings.
