Using corn extract to develop self-healing paint in Germany

Recently, Leibniz Institute for new materials in Germany announced that corn based paint has been developed This new corn based paint is expected to fill scratches and swirl marks If the vehicle encounters scratches and swirl marks, it will usually damage the transparent paint on the outer layer of the paint, while corn based paint can form a flexible coating by heating This kind of corn based paint is mainly extracted from corn starch This kind of paint has what scientists call "nano molecule", which contains cyclodextrin molecules Molecules can penetrate the polymer chain, which allows cyclodextrins to move freely along the chain At the same time, they don't fall off because of other molecules The self-healing ability of cyclodextrins comes from the fact that they are cross-linked with each other and become active through chemical reactions However, since all the molecules that need to work are hot, they need to work at 212 degrees Fahrenheit At present, scientists can shorten the repair time to one minute At a lower temperature, it will take several hours to make the molecule move However, the German company is not the first to break into the field of "self-healing coating" Last year, a company in Illinois called fenrab announced a self-healing coating Its formula also works on paint surfaces, and if something breaks the bond of the coating, it fills in scratches There is no information on how much the German Institute plans to charge for the lacquer, but it is trying to find partners to commercialize its technology At the same time, the process cost of Finn laboratories is about US $2500 (about RMB 16800) This is the price we pay for the perfect transparent coat.
