Ask an Expert: Is there a flexible, waterproof, conductive adhesive?

[HightonRidley]

I have a project I'm working on. It requires a flexible, waterproof, conductive adhesive that will bond to high density polyethylene. It needs to be flexible so that it can be applied to the plastic when flat and then the pastic curled to form a 1-2inch diameter cylinder.

It doesn't need to have very low resistance like you'd get from silver, copper or nickel-based paints. I don't need ahuge amount, a few tens of millilitres.

Online searches haven't brought up anything appropriate.

Thanks for any help.

Are you a student in grades K-12 doing a hands-on science project? If so, please tell us more about your project, such as the hypothesis, the experiments you are planning, and how you would use the observations from those experiments to test your hypothesis. Otherwise, there are other sites on the web where your questions would be more appropriate.

Thank you,
