Yes Rowland it would, i used a plastic storage box with argon in it when i fitted my cover glass. Both silicon and polyurethane require moisture to fully cure and in an argon bath there will be no moisture as it is displaced with the air. So fit it in the argon then remove it to air to cure. As long as you can see that you have no gaps between the cover glass and the sealant it should be fine. As far as outgassing is concerned, you would be using a very small thin layer of sealant, it will cure from the outside (air side) in. I have seen no evidence of moisture under my cover glass, even at -27C where it should freeze on a surface.
