A new coating on the underside of a car’s plastic roof is making a comeback as it can help protect against the heat and humidity from outside, according to a new study.
Researchers from the University of California-Davis found that the silicone coating was more effective at absorbing water vapor than a regular coating.
It was also more effective than a traditional coating that has a thick, waterproof coating that can be difficult to apply to the underside.
“This material works better in the extreme heat and cold conditions where the surface is exposed to higher levels of humidity and temperature,” said co-author Rachael Shanks, a professor of materials science and engineering at UC Davis.
“This material absorbs a lot more water vapor from the air, which allows it to be able to resist the high-energy chemical reactions that occur in the car’s interior.”
The research was published online in the journal Applied Physics Letters.
The coating on some cars is made of silicone, a synthetic material that can withstand extreme heat, but is extremely porous, so it can’t be easily removed from the car.
“If you’re using a paint or plastic coat, it’s basically just coating a surface with plastic,” Shanks said.
“It’s like using a sheet of foil on a piece of paper.”
Silicon coating is made by coating a layer of silicon with a thin layer of water.
The water acts as a barrier and protects the silicon coating from being exposed to heat.
The researchers found that if the silicone layer was too thin, it would stick to the surface and could damage the car if it was exposed to high temperatures.
“The idea is that the more you have this layer, the more it can absorb water vapor, so the material can be used to protect the interior of the car,” Shank said.
The coating could be used in all sorts of automotive applications, from the exterior of vehicles to the interior.
“It’s really important to make sure the interior is completely sealed,” Shao said.
“Because in most cases, the car will not be running at 100 percent efficiency, there will still be a high degree of humidity, so we need to be very careful.”
The study was led by Shao, who was also a research associate at the University at Buffalo.
The researchers used a combination of computer simulations and real-world testing to compare the effectiveness of the silicone coatings with a traditional coatings.
They found that they were able to absorb more water and create a thicker barrier than a standard coating.
“There are some areas that we didn’t test that were really interesting to us,” Shakesh said.
For example, there was a small area where there was more water that was lost when the silicone coated area was exposed.
“I think the biggest area we could have improved was the surface area of the silicon layer,” Shans said.
If you have a problem with the rubber tires on your vehicle, the coating might help you get them replaced.
“Even though it might be less than 1 percent of the total weight of the vehicle, it can actually reduce that loss of weight and it can make a big difference,” Shauls said.
Shanks is hoping to use the material in future products.
“We are excited to see how it is applied to other applications that are a little bit more specific to the automotive industry, such as automotive glass,” Shanski said.
