Horology for surface coating with a zwitterionic composition containing a phosphonic acid molecules and amine

摘要

The present invention relates to the use of amine molecules (N) and phosphonic acid compounds (P) for coating surfaces designed for use in the field of horology. Because these two types of compounds are alkaline and acidic, all kinds of compounds, regardless of whether they consist of inorganic materials such as glass, metals, non-oxidized materials (especially gold, rhodium and their alloys), or polymeric materials Form pairs of ions that interact with the surface. Taking advantage of the surprising complementary nature of these two types of compounds, we have developed a composition and coating process that can form a functionalized layer on any type of material used in particular in clockwork mechanisms. suggest.
