Coating wax for Copper wire to prevent discoloration (oxidation)

More
2 weeks 21 hours ago #2987 by Mr Ganda Sirait
Dear colleagues,

We produce bare Copper wire for power cable, can welding, wire hardness, etc.
And some customer very strict about wire surface quality for example no oxidation (discoloration).

I heard from some source that coating (waxing??) on Cu wire surface can reduce oxidation possibility.
Ladies and gentlemen, may be you have information about this coating system, please do not mind to share.

I heard there is two different way to apply this kind of coating/waxing:
1. apply on cooling system at annealler
2. apply at area between annealler and coiler

Please share your thought, experiences and advises.

best regards,

Ganda Sirait (Mr.)
