Cooling Coating Technology
What It Is
Next-generation cooling coatings are a big step in building technology. These coatings do more than just protect surfaces. They help control heat. The 3U No-Electric Cooling Coating is a great example. It uses special nanomaterials and strong polymers. These materials reflect sunlight and let heat out. Builders use these coatings to keep things cooler. They also help save energy and make buildings last longer.
Modern cooling coatings are not like old thermal barrier coatings:
-
They do more than just block heat. They reflect sunlight and send heat away.
-
Old coatings did not last long in tough places. New coatings are stronger and resist chemicals better.
-
These coatings stop damage from hot and cold, chemicals, and bad weather. This makes them good for hard jobs.
Next-generation cooling coatings are not just for protection. They help save energy, keep people safe, and are better for the planet.
How It Works
Cooling coatings work well because of smart science and design. The 3U No-Electric Cooling Coating has tiny particles of different sizes. These are put together in a special way. This helps the coating reflect sunlight and send out heat.
-
Nanoparticles near the top reflect many kinds of sunlight.
-
The coating sends out heat in the mid-infrared range. It uses the atmospheric window (8–13 μm) to let heat go into space.
-
This keeps the surface much cooler than the air, even in sunlight, and it does not need electricity.
| Scientific Principle | Mechanism and Explanation |
|---|---|
| Passive Daytime Radiative Cooling (PDRC) | The coating sends heat to space through the atmospheric window. This cools surfaces below the air temperature. |
| High Solar Reflectance (0.3–2.5 μm) | It reflects most sunlight. This stops extra heat from building up. |
| High Long-Wavelength Infrared Emittance | It sends out heat in the 8–13 μm range. This lets heat leave easily. |
| Micro- and Nano-structured Materials | These help scatter light and send out heat for better cooling. |
| Atmospheric Transparency Window | This lets heat pass through the air, so things can cool below the air temperature. |
These coatings use special science to reflect sunlight and send out heat. Tiny structures and new materials help the coating work well. This process is called passive radiative cooling. It works all day and night and does not need power.
Cooling coatings like the 3U No-Electric Cooling Coating use these ideas to help in real life. They make surfaces cooler, lower energy bills, and make places safer and more comfortable. They work well and are a smart pick for new buildings and factories.
Key Benefits
Energy Savings
Next-generation cooling coatings help save a lot of energy. They reflect sunlight and send heat away. This keeps building surfaces cooler. Air conditioning is needed less often. In hot places, cool roofs and coatings can cut cooling energy use by 67% to 87%. For example, in Phoenix, Arizona, buildings with these coatings save up to 6.64 kWh per square meter each year. EnergyPlus tests show these coatings work well in most climates. They are very helpful for buildings with poor insulation. Using less energy means lower bills. Owners get their money back fast, often in one to three years. People pay less for energy and feel more comfortable inside.
Tip: Using a cooling coating can help owners follow strict energy rules and get green building rewards.
Durability
Durability is a big reason people like next-generation cooling coatings. These coatings use strong materials and many layers. They can handle bad weather, UV rays, and big temperature changes. Old coatings might crack or break down fast. New silicone and multilayer coatings last 15 to 25 years if cared for. They do not break down, chalk, or peel, even in very hot or cold places from -60°F to 300°F. Additives like THIXATROL® make the coating stable and easy to put on. This means less fixing is needed over time.
-
Multilayer coatings like WO3/VO2/WO3 work well in high humidity and heat for over 100 days.
-
VO2/HfO2 sandwich films keep working for up to 16 years, even in tough places.
-
Silicone coatings reflect about 90% of UV rays. Standard coatings only reflect 65%.
These features help roofs and walls last longer. They lower repair costs and protect buildings from weather damage.
Sustainability
Sustainability is a main reason cities use next-generation cooling coatings. These coatings help cut greenhouse gas emissions. They do this by lowering the need for air conditioning. Studies show that passive radiative cooling coatings, like reflective paints, lower surface temperatures and energy use. This means less electricity and fewer refrigerants are needed. Both can cause climate change. White and colored coatings with high reflectance also help fight the urban heat island effect. They keep buildings and roads cooler.
| Type of Cooling Coating | Main Benefit |
|---|---|
| Cool Roof Paints | Lower roof temperatures, reduce AC demand |
| Cool Pavement Coatings | Reduce heat in roads and sidewalks |
| High-Performance Facade Coatings | Prevent heat absorption in building walls |
| Solar-Reflective Paints | Keep surfaces cool during peak sunlight |
| Heat-Reflective Roof Coatings | Maximize UV and infrared reflection |
Cooler surfaces mean less heat in cities. This makes people more comfortable and helps building materials last longer. These coatings help meet green building rules and city climate goals. They are a cheap and easy way to make cities more sustainable.
Industry Trends
Innovation Drivers
The industry is moving away from old coatings. New coatings do more than just protect surfaces. Nanocoatings use tiny particles to make thin layers. These layers help reflect sunlight and control heat. Some smart coatings can react to temperature or humidity changes. They can also sense damage or fix themselves. This helps them last longer and work better.
Scientists mix different materials to make new coatings. They use things like CaCO3, TiO2, and SiO2 in polymers. These mixes help coatings reflect more sunlight and send out more heat. For example, SiO2 microspheres can reflect almost all sunlight. They can make inside spaces up to 7°C cooler. Some coatings can lower surface temperatures by over 17°C in tests. There are also coatings that clean themselves. Some are thin and light for cars and electronics. These new features make coatings much better.

Installation
Some workers do not want to try new coatings. They trust the old ways and worry about how well new coatings will work. Old methods use more labor, but coatings can change this. Some people do not like that many cool coatings are white. Some building rules do not allow certain roof colors.
Researchers and companies are fixing these problems:
-
They make colored coatings that still reflect sunlight.
-
They design coatings that go on like paint or wallpaper.
-
They share clear data about how well coatings work, like solar reflectance index, so people can choose wisely.
Note: New coatings can go on many shapes and surfaces. Some come in big rolls for fast work.
Longevity
Builders and owners care about how long coatings last. Advanced coatings have strong bonds and special structures. This helps them stand up to heat, chemicals, and weather. For example, silicone resins with siloxane bonds handle heat and light better than old coatings. These coatings keep their color and stick well for a long time.
Thermo-reflective and ceramic-based coatings also stick well and stay strong. They keep out water and stop rust, even in hard places. Scientists keep working to make coatings last longer. They study how coatings age and how to fix or add more when needed.
Tip: Using primers and extra layers helps coatings last longer on rough surfaces like mudbrick.
