Aerogel coating
The outstanding performance of aerogel coatings fundamentally stems from the unique microscopic structure of its core component - nano-aerogel. This structure enables it to effectively block three pathways of heat conduction: solid heat conduction, air convection heat conduction, and thermal radiation.
Superior heat insulation and significant energy-saving effect: This is the core performance of aerogel coatings. Their thermal conductivity is extremely low, typically ranging from 0.030 W/(m·K) or so, which is much lower than that of traditional insulation materials. This means that a very thin coating (such as 2-3mm) can achieve the insulation effect equivalent to that of traditional insulation materials (such as 30-40mm), effectively reducing energy loss and achieving energy conservation and consumption reduction.
Outstanding fire resistance and flame retardancy: Aerogel coatings usually have good fire resistance ratings. Many products can reach national standards of A-level non-combustibility or A2-level fire resistance ratings, which can effectively delay the spread of fire and improve the safety of the coated objects.
Light weight and strong adhesion: Aerogel itself is one of the "lightest solids" in the world. Therefore, the coating formed after the drying of the paint has a low density and light weight, and will not impose excessive burden on the substrate. At the same time, through formula optimization, the adhesion strength between the coating and the substrate such as metal and concrete is high, and it is not easy to fall off or crack.
Waterproofing, water repellency and anti-corrosion: The aerogel itself is hydrophobic, which enables the coating to have excellent waterproof and moisture-proof properties. It can effectively prevent water vapor from eroding the substrate and prevent condensation on the surface of industrial equipment. Some coatings also have anti-corrosion functions, which can extend the service life of the equipment.
Green and environmentally friendly, easy to apply: The mainstream aerogel coatings currently available are mostly water-based systems, containing no or only a very small amount of volatile organic compounds, being non-toxic and harmless to the environment. They are suitable for various application methods such as brushing, roller coating, and spraying, and are particularly convenient for forming seamless insulation layers on the surfaces of irregular workpieces like valves and flanges.
Other properties: Besides the above characteristics, aerogel coatings generally have advantages such as sound insulation and noise reduction, aging resistance, long service life, and good thermal stability at high temperatures.
Insulation for high-temperature pipelines, storage tanks, reaction vessels, industrial kilns and other equipment in industries such as petrochemicals, power, and metallurgy;
Insulation and heat insulation for the interior and exterior walls, roofs, and floors of buildings, as well as for curtain walls and steel structure factories;
Heat insulation and fire prevention for battery packs of new energy vehicles, preventing the spread of battery thermal runaway; Heat insulation and fire prevention for transportation systems, ships, refrigerated vehicles, etc.;
Used for thermal insulation in spacesuits and spacecraft in the aerospace field; Fireproof coatings for cables; and the emerging high-performance outdoor products (such as cold protection clothing, sleeping bags, insulated cup covers, etc.)
