Fireproof Coating Market Overview
Fireproof coating is a special coating that can reduce the combustibility of the coated surface, stall the rapid spread of fire, and increase the fire resistance limit of the coated material.
In 2016, the global fireproof coating output value scale of 1.16 billion U.S. dollars, an increase of 5.5%; in 2017, the global fireproof coating output value scale of 1.23 billion U.S. dollars, an increase of 6.2%; in 2018, the global fireproof coating output value scale of 1.3 billion U.S. dollars, an increase of 5.7%; in 2019, the global fireproof coating output value scale of 1.37 billion U.S. dollars, an increase of 5.6%; in 2020 The global fireproofing coating output value scale of $1.44 billion in 2020, an increase of 5.2% year-on-year.
The demand and consumption of fireproof coatings in 2021 is affected by the blockade policies and quarantine measures implemented by governments across the world, reducing the global value size to USD 1 billion due to the ongoing Covid-19 global pandemic. However, with the global economic recovery, the fireproof coatings market is expected to grow at a CAGR of 3.7% during the period 2022-2030.
Europe currently holds the largest share in the fire protection coatings market. In Europe and North America, technical regulations related to fire safety in the construction and manufacturing industries are implemented to ensure safety and prevent fire accidents. For instance, in the U.K., building owners, designers, occupants, and operators require fire risk assessment along with quality inspection of various building materials. The booming construction industry in several countries and regions in Asia Pacific and Latin America is significantly increasing the demand for fire protection coatings, especially in Asia Pacific, where continuous investment in construction has a significant market driving effect on fire protection coatings. Asia Pacific is expected to be the fastest growing market for fire protection coatings during 2022-2026.
Principle of Fireproof Coating
1. the coating itself is non-flammable and slows down the burning of the object or the deterioration of its performance due to high temperatures.
2. low thermal conductivity of the coating, which slows the transfer of heat from the heat source to the substrate.
3. the decomposition of the paint at high temperatures to produce an inert gas that dilutes the concentration of the accelerant.
4. adding fire retardant chemical elements of various fire retardant coatings, the solid can be rapidly decomposed after heat to generate nitrogen, oxygen, ammonia and other groups, and organic groups and free radicals cyclic chemistry, so that a series of chain reactions interrupted.
5. The coating creates a protective layer on the surface of the substrate through a series of physicochemical changes that insulate it from oxygen and slow down heat transfer.
Fireproof Coating Product Types
Fireproof coatings mainly include non-intumescent and intumescent fireproof coatings of two types.
Non-intumescent fireproof coatings consist of non-combustible base materials, inorganic fillers and flame retardants, of which inorganic salt system accounts for the mainstream. The thickness of non-intumescent coating is about 25mm, and it belongs to thick fireproof coating according to the thickness classification. Thick fireproofing coatings are widely used, including cement-based thick fireproofing coatings, which are popular because of their low price and cost. Non-intumescent coatings have high fire resistance limit and low thermal conductivity, so they have greater advantage and value in places with high fire protection requirements. However, its coating thickness is large, and the weight of the coating is a relatively large burden on the building structure, which can easily lead to peeling and higher requirements for the bonding ability between the coating and the substrate, in addition, regular maintenance also increases the construction cost, and there is an urgent need to reduce the coating thickness and reduce the self-weight.
The main structural components of intumescent fireproof coatings are film-formers, acid sources, carbon sources, foaming agents and filling materials. The common flame retardant structure system is the P-N-C flame retardant structure system composed of ammonium polyphosphate, melamine and pentaerythritol. Under the action of high temperature, the acid source is decomposed into acid by heat, and the acid makes the carbon source charred after dehydration, and esterification reaction occurs to a certain extent, forming residual carbon material. The residual carbon is an important part of the gas foam layer, and the foaming agent produces non-combustible gas after decomposition. The gas skeleton rises together to form a uniform and dense porous gas foam structure, which is tens of times thicker than the film layer. The carbonization process will absorb a lot of heat, and the decomposition of the foaming agent will produce non-combustible gas, and the foam layer will isolate oxygen and heat, which is conducive to delaying the spread of fire. Intumescent fireproof coating has a base thickness of less than 3mm, and belongs to the ultra-thin fireproof coating, which can expand up to 25 times in case of fire, forming a residual carbon layer with fire insulation, effectively extending the fire resistance time of the substrate, which is the fastest growing in fireproof coating varieties, and the most widely used is wood structure and steel structure fireproof coating, which is expected to have a compound annual growth rate of up to 8.5% in the next few years.
Fireproof Coating Market Outlook
Developed countries such as Europe, America and Japan have an early start on the research of fireproof coating products and are ahead in application technology. The U.S. 3M, Denmark Haihong old man, the U.S. Xuanwei, India Lloyd company, the United Kingdom Nullifire company, the United States PPG, the Principality of Liechtenstein HILTI company, Finland Teknos company, Japan Kansai coating, the Netherlands Akzo Nobel, the United States Carbo Laing company, Germany Rudolf Hensel company, Norway Jotun, etc., in the global market occupies an important position. With the subway in many big cities around the world and high-rise buildings relieving the pressure of insufficient urban ground space, there are more and more various supporting facilities, which need more fireproof coatings. The relevant departments in many countries and regions are also gradually strengthening the fire safety regulations, which also brings favorable opportunities for the development of fireproof coating market.
At present, a more active research area in the field of fireproof coatings is the application of fluorine-containing resins and silicone modified resins to improve the weather resistance and corrosion resistance of fireproof coatings, to provide ideas to solve the outdoor application of ultra-thin fireproof coatings, which is an important development direction for super weatherproof fireproof coatings.
