    Has anyone found an adhesive that sticks to Teflon? Seems like I'm trying to do something that shouldn't be done. I have some Teflon blocks that I want to use as handle material, on a spoon. The handle will be 6" with a 3" split over the spoon tang that will have 2 pins through it. I would like to use this if possible, but may end up with another handle material if I have to.

    I would expect you will need to rough up the surfaces your are joining but beyond that I am not sure what if any adhesive will actually bond to that material.

    Silicone is another along with the polyethylene group are very difficult .
    ALL smooth surfaces should be roughened before attempting to paint or glue ! !

    Trying searching "PTFE adhesive" or "Teflon adhesive", and you should get some results.

    Here's an example:

    Just use Corby bolts and a good sealant type adhesive. The adhesive won't really bond the PTFE, but it will make a tight seal. The bolts will provide the strength.

    I did have some limited success in bonding silicone sheet together , using silicone sealer. I also remember talking to a plastics guy - he said if you developed an adhesive for polyethylene you would be a billionaire overnight ! :(
