摘要:
The present invention describes the highly advantageous properties of a mixture of thiol-perfluoropolyether (PFPE) molecules with perfluorinated bisphosphonic (PF-BP) compounds. This mixture makes it possible in effect to obtain a lipophobic behaviour (also referred to as “epilame” effect) with common watch-making lubricants on all the materials tested, including metals, inter alia gold and alloys thereof, ceramics and semiconductors, and gives the surface treated a good resistance to ageing and to cleaning products.
摘要:
The present invention describes the highly advantageous properties of a mixture of thiol-perfluoropolyether (PFPE) molecules with perfluorinated bisphosphonic compounds (BP-PF). This mixture in fact makes it possible to obtain a lipophobic and hydrophobic behaviour on numerous materials, including metals, inter alia gold and alloys thereof. It makes it possible to prevent corrosion, and to limit deposition of soiling and microbiological contamination on these surfaces, while at the same time conferring good mechanical strength and resistance to ageing and to cleaning products. It also makes it possible to lubricate the metal parts that it covers.
