i tried to find info on it but can't. I seen that some weld thru primers have over 90 percent of zinc in them. Anybody know how much the SEM has in it?

I have a can however it does not say anywhere on it how much % it contains.
As I remember it has to have over 90% to be a "weld thru" and SEM had it.
