摘要:
The present invention describes the use of amine molecules (N) and phosphonic compounds (P) for coating surfaces intended to be used in the field of horology. Since these two types of compounds are alkaline and acid in nature, they form pairs of ions that interact with all types of surfaces, whether these are composed of mineral materials such as glass, metal, non-oxidized materials (inter alia gold, rhodium and their alloys), or also polymeric materials. Taking advantage of the surprising complementary nature of these two types of compounds, the present inventors propose a composition and a coating process that enable functionalization layers to be formed on any type of material, in particular those used in clock mechanisms.
