On the subject of Torr-seal, I believe that Hysol Epoxi-patch 1C is nearly
equivalent to Varian's epoxy and is much much cheaper. I have used Hysol 1C in
vacuum on many occasions and, as long as temperature extremes and ion beams
avoid it, it performs very well.

Re: Another sealant (Vacseal)
The material safety data sheet on the vacseal website gives the ingredients and I think they are usually listed with the dominant component first.

That's what I picked up. Dunniway's price isn't to bad.

Re: Another sealant (Vacseal)
The MSDS gives the hazardous components of Vacseal, but does not say which solvent is the dominant one. Another site says that wet Vacseal can be cleaned up using toluene, but the dried resin requires a nastier solvent like MEK or methylene chloride. It sounds like the stuff could be thinned with toluene, which is preferable (but not by much) to using perchloroethylene or methylene chloride, two of the other nasty solvents contained in Vacseal.
