When I bought some siding the other day, the receipt had a note printed
on it advising me to treat all cut edges with a "zinc naphthenate-type"
I'm curious, since I've heard of and used copper naphthenate (aka
"copper green"), but never heard of the zinc compound. What's the diff?
Is one better? Better for certain situations?
I like using copper green; the first time I encountered it, I thought it
must be terribly toxic stuff, because of the smell and the name of the
compound, but after checking the MSDS found that it's actually pretty
safe. And I actually like the smell.
Hmm; just looked it up, and zinc n. seems to be much more toxic than
copper n. Compare
(copper). Zinc n. is listed as a "PAN Bad Actor Chemical" and as a
"Developmental or Reproductive Toxin", where copper n. is neither.
