TRIVALENT VS. HEX FREE PLATING

IS THERE A DIFFERENCE BETWEEN "TRIVALENT" PLATING AND HEX-FREE PLATING. I UNDERSTOOD THEY WERE ONE AND THE SAME.

Hi, Robert. Your question is a bit vague when asked with no context; plus it's hard to answer absolutely because of semantics issues.

For example, I suppose there actually is no legal reason why some small manufacturer could not call their product "Trivalent" if it was predominantly trivalent rather than completely trivalent and they were trying to get rid of it. Madison Avenue does worse than that every day :-)

But yes, according to the spirit of the law "trivalent" and "hex free" are the same thing.
