I couldn't find anything about breathability of the
superhydrophobic coating. They say it works by trapping a layer of
air on the surface of the material, so it might breathe. However it
is supposed to be nanotechnology so the pores would obviously be
small and it might not breathe easily, sort of like Gore-Tex.
Unfortunately for caving applications, it sounds like it
might not hold up well. Several places they mention that abrasion
reduces performance.

According to the MSDS, The LD50 for rats is 5800 mg/kg (i.e., it takes
a lot to kill 50% of the rats) and it is not a hazard to fish (the
LC50 is also high). It breaks down relatively rapidly in the
environment. Just for reference, LD50 of water for rats is >90 ml/kg

I wonder what this means for its useful life in protecting things.
Presumably, you need to recoat regularly.
