Torsten,
pH13!!! None of the ordinary polymers will withstand that. Are you sure of
the requirement? I've never seen anything like that. I don't think even
Parylene will be enough. I used Parylene C for military encapsulation of
parts that had to pass salt spray for weeks, high temperatures and like, and
we found that to withstand such a harsh environment , the Parylene had to be
so thick, that the process had to be modified. The cost per package had been
quite unrealistic.
I would try ceramic spraying, that's probably your solution. There are lots
of variants. I can't tell you which one suits best. Some are for
electronics, others not. You better check the below URL and call the
respective ceramic spray specialist.

Good Luck
