Need to make a couple of solvent weld joints. The tine of Osmaweld
solution that I have must be getting on for fifteen years old. Does it
have a limited life? Should I get some fresh just for a couple two joints?

I don't know about the actual life, but the tin I bought (5 years ago)
had an expiry warning of about 12 months.

You'll probably find it has turned to jelly in the tin. If not it
will be OK.

The one thing to watch out for is there are PVC and ABS plastics.
Some sovents work on both, some don't, read the tin.

Dad has a tin of Tensol Cement (solvent weld for perspex) which says
best before Aug 1969. It still worked when I last used it a couple of
years ago.

I think with solvent weld, it's all down to having enough solvent left
in the glue. Some solvent welds are just solvent, others have some of
the intended substance dissolved in them too, to act as a bit of a filler.

I had a similar tin. I tried a test joint with it. No problem at all,
I broke the pipe rather than the joint, then I cut the joint and
examined the mating surfaces - good weld.
