Nanotechnology (Greek: nãnnos = dwarf) brackets together a great many technologies that deal with structures measuring less than 100 nanometres. A nanometre is one-billionth of a metre. In perspective, this is equivalent to the size of a football in relation to the earth. When applied to surfaces treatment products, nanocoating’s, form chemical structures that can yield super-hydrophobic, self-cleaning effect and even anti-corrosion behaviour. This are important characteristics in the future of automotive sealants or home surface protection.
