EFFECT: method for coating metal surfaces of substrates and objects coated according to said method is provided. 26 cl, 38 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) (19) RU (11) (13) 2 669 672 C2 (51) МПК C23C 22/34 (2006.01) C23C 22/74 (2006.01) C23C 18/12 (2006.01) C09D 5/08 (2006.01) C09D 103/14 (2006.01) C09D 105/00 (2006.01) C09D 105/06 (2006.01) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C23C 22/34 (2006.01); C23C 22/74 (2006.01); C23C 18/1241 (2006.01); C23C 18/1254 (2006.01); C09D 5/084 (2006.01); C09D 103/02 (2006.01); C09D 103/12 (2006.01); C09D 105/00 (2006.01); C09D 105/02 (2006.01); C09D 105/04 (2006.01); C09D 105/06 (2006.01) (21)(22) Заявка: 2015125055, 25.11.2013 25.11.2013 Дата регистрации: Приоритет(ы): (30) Конвенционный приоритет: 26.11.2012 DE 10 2012 221 520 ...
