How can this not be electrically conductive but have water in it as another answer that was given, the 2 contradict each other?

That's a great question! Once the Boron Nitride Paste has been heated to 100 °C, the water evaporates and all that is left is the paste. Usually, computer components do not reach this high of a temperature, so the water inside the initial mixture will not evaporate.

Is this more of an 'adhesive' by chance? i'm looking for a tidier way to keep water cooling blocks on my nema-17 steppers in 80c air, and love bn .

Once the Boron Nitride Paste is dried, it is hardened which makes it act as a weak adhesive. It would probably not be the best idea to use it to keep water cooling blocks attached to a stepper motor.

Can this be used as cpu thermal paste? if not, why not?

It is not recommended to use our Boron Nitride Paste as CPU thermal paste as our Boron Nitride Paste contains water. A proper thermal grease would be a better option for this use case.

I need a thermal paste to connect a thermostat cutoff switch to the outside of an oil heating (500 deg F) popcorn kettle. Will this work?

Slice Engineering Boron Nitride Paste is a thermal paste for improving conduction. We do not recommend that it be used as an adhesive.
