We're talking a lot to a few races of the coating that some top teams are using inside of the rims. A f1analisitecnica received a tip that finally shows us what it is. The material used is a kind of liquid glass with black opacifying pigment that is used to improve the thermal conductivity. The only world producer of this innovative product is the Nanopront and the product is called Polysil. It is a based on atomic silicon coating with revolutionary features that allows the protection of reconditioning the substrate surface structure. With a layer of a few microns high surface hardness (9H) ,the surfaces also have a high resistance all'abrasione.Questa “liquid glass” weighs 95% of a normal painting and has a resistance to temperatures of 1100 ° C. Currently the color coatings of a wheel of Formula 1 weigh from 65 to 85 grams. Thanks to this product the coating weighs only 5 grams and in addition to improving thermal conductivity gave an improvement of 3 points to the CFD as are generated less turbulence.
