I hate it when I open a new tube of silastic sikaflex etc. etc. to use only a small amount and find a week later the whole bloody lot has gone off . Has anyone got a solution for sealing the tube . Thanks .
Ramona said.. Sikaflex can be stored in a freezer. Silastic tubes with the screw lids keep well if you make sure the thread is kept clean each time you use it.
Bruski068 said.. I usually seal the opening with a screw of the appropriate size.
Most general purpose sealants are RTV (room temperature vulcanization) I always keep them cold and sealed like the guys have mentioned above. Even Fixtech 15 keeps real well like this.

Don't think the missus would appreciate that too much.
+ 1 on the screw in the top and store in the workshop cupboard.
I use Fixtech and wrap it in gladwrap like the hardware shop man said. But it only works to a point with the tip of the nozzle going hard, the stuff in the tube stays OK. So I've taken to putting on a fresh nozzle when the time comes to use it and digging out the soft stuff in the used nozzle and pushing the hardened stuff out with the shank of a drill. I can now use the nozzle again.
I have tried most of the suggestions with almost no succes with marine Sikaflex. I can almost believe the freezer would work except concerned it may be served baked for dinner one night. Will give it ago as about to open a new tube for a small job
In the good old days at the boat yard we only got sikaflex and could thread a bolt or screw in the nossal and would be good to go right through the tube. Over the years I have noticed they changed the brew and now it seems it goes off in the tube! hence I got onto fixtec up in Qld for my leaking "Chainplates" (common problem on Duncs) and found it would last me a few months before going hard in the tube. Haven't looked back at sikaflex since I made the change. As long as its polyurethane sealant.
Sikaflex is cheaper but for small jobs I use marine goop. It's in a tube and a bit expenside at about 20 a tube. It's a must have on e boat. I've even repaired a wine glass with it. Stuffs amazing.
Same annoyance for super glue but I was at Bunnings the other day and some clever person somewhere has invented half size super glue tubes and you get 5 in a packet. SO when the first half size one goes off you dont loose so much and youve got 4 more.
