New standard for plug contacts in high-voltage applications
Our silver-graphite dispersion electrolyte ARGUNA® C-100 is specially developed for connector contacts used in high-voltage applications (e.g. high-power charging / HPC). A stable layer system with maximum charging performance without restrictions over the entire lifetime of the charging connectors is the result - and thus the new standard for the industry.
Graphite particles perfectly embedded in the silver layer achieve extraordinary abrasion resistance and thus the high reliability and durability of the plug contact required by the industry. This is made possible by a optimized graphite component which, embedded in the silver matrix, serves as a solid lubricant. In this way, abrasion on the entire contact zone during the mating process can be reduced to a negligible level.
ARGUNA® C-100 thus offers a contact layer on your connectors that is clearly superior to conventional coatings: more than 50,000 mating cycles* without adverse wear and therefore the best possible charging performance at all times without restriction - the new standard in this field.
