Conformal coatings materials are applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that if un-coated (non-protected) could result in a complete failure of the electronic system.

Usually conformal coating is used to protect the PCB from damage since it will be exposed to harsh environment...

Examples are Burn In Boards used in semiconductor manufacturing. The board is subjected to 250 deg C for 1000 hours with a device under test (usually an IC). Then after 1000 hours, the IC will be tested if it is still electrically good.

I have some thin craft copper which I am going to apply some (100kv per mm) conformal coating to on the rear side of (to act as a dielectric surface on the back of a conductive) to make some EMI material.
