Product with protective coating

Abstract

The application provides a product with a protective coating. Prepare a first precursor dispersion comprising a first active organic precursor, and the first active organic precursor is a fluorine-free monomer. Prepare a second precursor dispersion comprising a second active organic precursor, and the second active organic precursor is a fluorine-containing monomer. Apply the first precursor dispersion to a product body, and dry the applied first precursor dispersion to form a first dried layer. Apply the second precursor dispersion to the first dried layer to cover the first dried layer, and dry the applied second precursor dispersion to form a second dried layer, so that the first active organic precursor and the second active organic precursor are polymerized to obtain a product with a protective coating.
