In my prior post, I meant to say lengthy... Anyway, an alternate and faster curing strategy for Sylgard (I validated this during my tissue engineering postdoc many years ago) is as follows:
4 hours @ 65C followed by two hour cool-down period. If you feel that the Nixie tube in question and its associated base can withstand 65C, then this would be a much faster approach. Sylgard is a superb material for bonding glass, as it forms covalent bonds with the siloxane moieties on glass surfaces. It is also optically clear and an excellent electrical insulator. Alternatively, most two-part epoxies should bond well, but not all formulations are optically clear. Hope this helps, Ulysses -----Original Message----- From: Ulysses J.

Curing time is length, however, at several days.

Any recommendations on the type of glue to use to fix it. I would like to use something that is transparent when dried. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
