ice melt

I've always had a well founded and severe fear of using any type of ice melt
product around our hanger entrance. As a farmer, I know what ammonium
nitrate, ammonium sulfate, potassium chloride etc. are and what they can do
to your equipment. Recently our FBO started selling an palletized ice melt
made of ammonium sodium acetate, the dry prilled form of the liquid product
that they spray on the runways as a ice preventative.

Does anybody know the corrosive properties of ammonium sodium acetate?

Thanks
Jim



We started getting quite a few of our pups back from European operators with the cad plated parts very corroded. Turns
out the Europeans were using some sort of new deicer stuff on their runways and all. Unfortunately I do not know what
it was exactly, but you can do some testing on your own parts. Get some old screw hardware from your local mechanic
and see what happens...


That pups should be pumps, as in hydraulic.

Cadmium plating is routinely stripped from the base metal using an amonium
nitrate solution, hence the corrosion.

That may be the case, and maybe ammonium nitrate was the 'new' material that was being used over there, but it the
problem was sudden and they are no longer using whatever-it-was because the problem has gone away. Almost all of the
steel components on the pumps are cad plated, as well as many of the landing gear parts. There was quite an uproar there
for a while...
