Chemical metallization process, also referred to as chemical or catalytic chromium, based on the reaction in silver mirrors and makes it possible to apply to surfaces, specular metallic coating having high reflectivity. For the chemical plating process uses a special spray equipment and chemical. reagents enabling metallization and applied metal mirror coatings on any hard profiled products and small parts with almost any dimensions.

1 When "plating" and "gilding" method of chemical metallization of various parts and products, the main objective is to obtain in this manner, the metal coating is no different from the metal coating obtained by galvanic deposition. Such electroplating, to obtain a high decoration, usually applied on a perfectly smooth, polished or polished metal surfaces. Therefore, to simulate as close as chrome or gold-plated surface, metallic finish should always be applied to the primed surface perfectly smooth.
2 Polyurethane A / m of coatings have good adhesion properties, but with time can produce a darkening of the surface layer of the plating of silver for reaction with sulfur. To improve the adhesive properties of the thermal treatment is carried out (for example, the burner flame), which is used for the formation of coatings on the surface of the carboxyl groups, to improve its "wettability" (prior to sensitization / activation process) and increase thereby adhesion primer coating properties. When heated, the metallized products covered by a / m polyurethane coatings above 130 ° C may be a significant deterioration in adhesion with a layer of metallization.
3 Many polyurethane or akriluretanovye a / m paints with high film formation speed (speed of "linking"), do not have high adhesion with a metallic coating.
4 Kolirovochnye pigments are added to the a / m of paint, do not darken or discolor from exposure to UV radiation. Therefore, even the most expensive A / m lacquers do not have high light resistance because It does not contain in its composition specially selected light stabilizers and UV absorbers. "Light-transmitting" pigments used to color the metallized surface, very "sensitive" to the UV light (sunlight), so when using a / m varnishes, through 6-12 months possible darkening of the metallized surface.
Options for metal coatings
Application: tuning cars and motorcycles, finishing marine boats, restoration of worn chrome coatings on the retro cars, outdoor advertising products, logos and trademarks, luxury furniture, designer goods, architectural and sculptural workshops, souvenir products, sanitary ware, church decorations and more.
