Abstract The present invention relates to a process for forming and applying a hydrophilic coating that is extremely slippery when wet to a molded plastic or metal part, in particular a razor or a razor-blade unit, in which a solution that contains a water-soluble polymer, in particular polyvinylpyrrolidon, is applied to the molded part and there hardened, as well as the razor that is of plastic such as polystyrene or ABS or metal, this being provided with a device that increases its gliding ability. The invention also proposes that the solution that is applied to the molded part consist of the water-soluble polymer, in particular poly-N-vinylpyrrolidon or a copolymer thereof, one or a plurality of radically polymerisable vinyl monomers, and a photoinitiator that decomposes into radicals when irradiated, and wherein the solution that is applied is hardened by exposure to ultraviolet radiation. |
