Potting compound recomendation for Maytech

Hi all,

I while ago I ordered a Maytech remote and did not work when arrived.

After investigation, the connection of the screen cable was not doing a good contact ad I had to open the potting.

I would like to re-purpose the controller. I’ve tried re-potting on top but so far silicone, sikaflex or epoxy do not stick to the original Maytech potting.

Any recomendations of a potting compound which would stick? Otherwise, can someone recomend a similar potting (flexible)?

Thanks,

Jordi
