Why is white metallic coating on specific parts of interior housing?

[modernista]

It's silvery white with sparkles on the housing under the dock port ribbon cable and a few other ribbon cables, around the bolts and some random places. I am thinking it may be for better adhesion or conductivity. Wondering what happens when if it gets accidentally removed.


Please comment only if you REALLY know what it is.

Going to need more information. What iPhone? Do you have pictures of the white metallic coating?

I found a pic online of the two latest models. The 6s being on the left.

The 6 on the right appears to have it (silver/white metallic coating) in very specific locations while the 6s has it everywhere.

Thanks!

I can't really tell what you are talking about from the pictures on the link - however.
There used to be(and still may) white areas to help determine if phone had been in the water - they turned red if wet. Again since I can't tell exactly what you mean from the link - not sure if this helps

The water damage stickers are tiny and on a few parts. This is paint on the housing. It is metallic and shields from heat or static or makes it conductive or .... ?
The area with the big scratches is what I am referring to. You can see it around several bolts and radom places.

Maybe I'm not understanding but I can't see anything coloured white. You could try contacting the guys at Ifixit.

Your pictures just don't show what you are describing.
Maybe you could show a picture of that area where you removed that coating on YOUR iPhone?

I suppose your question is: Is that coating conductive, insulating, or (the likely answer) makes no difference whatsoever?
