Self repairing paint could mean trouble...

Apparently scientists created a special self repairing paint coating that allows paint to re-bond itself over a scratch when it bakes in the sun. The process takes and hour to fix a scratch. They call it "no muss, no fuss" but unfortunately for us we make a living do the "muss and fuss" of paint correction.



Hopefully it never hits the market or it costs $15k to coat a car.



Here is the article:



In another case of Nature to the Rescue, scientists have come up with a polyurethane coating that repairs itself in the sun. The secret ingredient: chitosan, which comes from the shells of crustaceans and is also used for water filtration, blood clotting and as a diet aid. The common principle appears to be that it as a binding agent, i.e. it wants to hold certain things together.



If your car is scratched and it has the chitosan-injected coating, when put in the sun the chitosan "bonds with other materials in the substance, eventually smoothing the scratch" in less than an hour. No muss, no fuss, no messy clean up. However, the magic only works once -- the coating can't repair itself in the same place twice. Researchers also haven't yet studied how wide a scratch can be before it cannot heal itself.



Nevertheless, self-repairing paint powered by the sun is still a terrific development, especially for those folks with shiny black cars on which even tiny scratches seem to scream for attention. No word on when or if it will ever be available, but the team behind it has a patent pending and is thinking about the business opportunity. Thanks for the tip, everyone!

I'm pretty sure if something like that hits the market it'll be really expensive,plus,they didn't mention anything about self-repairing swirlmarks or bird droppings etc....,so i wouldnt worry about this for maybe more than a year or possibly more:bigups
 
I don't see this as anything big in the next 20 years. People who dont have this paint, if it becomes produced widely (which will likely be QUITE expensive especaillly since itr only works one) will still need repair. And if this paint only works once, then who comes in after that?
 
Well, it can only repair itself in the same place once so after that it will scratch like normal.



So for all those who improperly wash there car and swirl it up this paint will not help them at all since it can only repair itself once...



I wouldn't worry about it at all.



For what people will pay for it, their expectation will be high adn they'll think they don't have to care for there cars and then they'll see how bad it looks cause it can't keep repairing itself they will be angry and call us to buff it out....:bigups

First of all, that doesn't make any sense, and second, I read about this somewhere else the other day and they didn't say anything about that, in fact, IIRC, they said they didn't know how many times it would "heal" (or perhaps for how long the process would continue to work) because they just invented the stuff.
 
Infiniti already has it on some models. Not sure if it only works once, or how well it works. It is definitely available on some 09 models though.
 
I fail to see how this spells "trouble". Also, this isn't technology that we may or may not see in 20 years. It's here right now. Infiniti has self repairing paint on certain models.
 
So dug up some info on the Infiniti paint, it is not buffable/clayable and has an effective lifespan of about 3 years, and fixes fine to moderate scratches. essentially, the paint does not dry and will slowly fill in the scratches from anywhere to 15 minutes to a week. At least that's what I understood.
 
Even if all cars eventually have this paint, there will still be a lot of 3 year old cars out there needing attention.

I know you read a different article, but this one says that it will only heal an area once.

Here's what I read:



Polyurethane Coating Self-Heals In Ultraviolet Light.

The Discovery Channel (3/12, Bland) reported on "a new polyurethane film developed by scientists from the University of Southern Mississippi" that uses "a new macromolecule" to create a polymer that "is capable of repairing itself" when exposed to ultraviolet light. "The new coating is 99.99 percent standard polyurethane," and "the remaining 0.01 percent is either a four-molecule oxetane ring or a long rod of chitosan," which "is closely related to chitin." While scientists say "that it should be able to repair most scratches indefinitely," they added that "since the material is so new, they haven't been able to conduct long-term tests." The relative cheapness and availability of chitosan, as well as its low cost and environmental friendliness, are also pointed out. BBC News (3/13), the UK's Press Association (3/13), New Scientist (3/13, Kleiner), and Wired (3/12) Science blog also covered the story.
 
Interesting. Thanks for the info Setec. From that info, you are right, it sounds like it could continue to heal itself multiple times.
