The invention relates to a method for coating objects, particularly plumbing fixtures, having metallic surfaces. According to the method, at least one organosilane is applied during the so-called sol-gel process after an optionally provided pretreatment step that serves to activate the metallic surfaces, and the coating obtained thereby is transformed into a polysiloxane coating. This transformation of the coating into a polysiloxane coating preferably ensues by a thermal treatment effected at temperatures of < 100 °C, preferably < 70 °C.
L'invention concerne un procédé permettant de munir des objets d'un revêtement, notamment des articles d'installations sanitaires, à surfaces métalliques. Après une étape de traitement préalable éventuellement prévue, pour activer les surfaces métalliques, au moins un organosilane est appliqué dans le cadre du procédé dit sol-gel et le revêtement ainsi obtenu est transformé en un revêtement polysiloxane. Cette transformation du revêtement en revêtement polysiloxane s'effectue de préférence par traitement thermique à des températures < 100 ·C, de préférence < 70 ·C.
