[labnetwork] Anti-seize coatings for VCR threads

[Travis Wade]

Hi Dan,

I've had good luck with Loctite 37617, silver-based antisieze.

https://www.amazon.com/Loctite-37617-6PK-Silver-Grade-Anti-Seize-Lubricant/dp/B0053ZS1Z8?th=1

I only use it on non-vacuum wetted surfaces, typically conflat flange
bolts, so I cannot comment on outgassing, but I would have no aversion to
applying it to a VCR thread.  The glue-stick style applicator is
wonderfully convenient.

Good luck!
