<p>The method involves applying aqueous polymer dispersion on a patination surface of a copper product, such that the polymer dispersion penetrates into surfaces near the surface of a porous patina. The aqueous polymer dispersion is dried in the porous patina, where the polymer dispersion with the patina forms a water vapor diffusion-permeable compound. A quantity of 5 to 10 grams per meter square of the aqueous polymer dispersion is coated on the patinated surface, where the aqueous polymer dispersion is applied in drop form on the patinated surface.</p> |
