Finding scratches in your car is definitely a headache, and for some, it would be considered a nightmare because they would be hurting their wallets just to make their cars immaculate once again.
However, scientists from Korea have created a self-healing coating that would erase scratches from your car after 30 minutes of exposure to sunlight.
Erasing Car Scratches With Sunlight
As reported first by New Atlas, the novel coating has a polymer network built on acryl polyol and has a structure known as a hindered urea. In essence, the polymers feature dynamic chemical linkages that can separate in reaction to a stimulus and reunite in their initial configuration, which easily erases scratches.
This is made possible through heat, which serves as a trigger, and is supplied by an organic photothermal dye that absorbs infrared light.
The team's experiments on a model car demonstrated that the coating repaired scratches in 30 minutes under midday sunlight.
The scientists also showed that the procedure could be significantly sped up under concentrated light. In fact, the team repaired a car scratch in less than 30 seconds by reflecting sunshine through a magnifying lens onto the damaged area.
According to the team, the novel coating has a few benefits compared to current self-healing coatings. They claimed that it requires significantly less energy to function than conventional inorganic equivalents, which typically call for heat guns or intense UV lights.
Their self-healing coating contains organic photothermal dyes, which require less energy to function, according to New Atlas.

Transparent Coating
New Atlas further noted that other coatings, such as Nissan's Scratch Shield, take up to a week in order to heal any kind of car scratches, whereas the new coating can erase damages in the same area various times in 30 minutes or less.
To top it all off, the new coating is transparent, so it will not compromise the color of the car, and it can be applied using available spray-coating methods.
Future applications for the created self-healing material include coatings for construction materials, electrical equipment like computers and cellphones, and transportation applications.
Additionally, it is anticipated to aid in achieving carbon neutrality by lowering the use of toxic organic solvents, which are produced in significant quantities when repainting automobiles.
