As a result of the high costs of coatings, many buildings in the U.S. are opting for non-coating, powder coated architectures.
According to a recent study, only 7.5 percent of building coatings can withstand extreme temperature variations of -30 degrees Celsius or more, and a majority of the time, these coatings only last a few months.
The new coatings offered by architecture coatings are made from carbon nanotubes.
They are lightweight and are able to adhere to surfaces in a way that the typical coating does not.
This is achieved by coating a nanotube layer of a particular color or a pattern on the coatings surface, rather than using a conventional polymer.
In a study published by the journal Advanced Materials, scientists demonstrated that coating a white material with a powder coat would be able to maintain the original color, even at temperatures of -180 degrees Celsius.
Another study published in Advanced Materials found that nanoparticles coated in a powder form would be less dense than conventional coatings.
For a powder coated architecture, the researchers created a layer of nano-scale powder particles, which is capable of covering a surface at a density of up to 10 nanometers.
These nano-sized particles, however, are very fragile and are prone to shattering at high temperatures.
One potential problem is that the nano-size particles are extremely difficult to remove from the surface, leading to brittle coatings that may degrade over time.
Despite the challenges of coating an architectural surface, coatings have been found to be highly effective in other areas, such as building materials.
Building coatings were first used as a way to improve insulation in buildings, which has a major effect on air quality.
Building coatings also help in the treatment of water.
Coating an exterior wall with a layer made from nanostructured materials can reduce the weight of the wall, which may reduce the impact of leaks or damage to structural components.
Even if a coating has no practical applications, it may help protect your building from moisture.
