Storing Vulkem or Sikaflex

[cameront120]

Has anyone found a way to store a tube of either of these sealants, once the tube is open? I'm tackling a bunch of small jobs, as time permits, and don't really want to have to buy a new tube every time I need a few cc's of sealant for something. It seems that once open to the air, curing starts to take place. I've even tried wrapping the tip with celophane, but the curing process seems to carry on regardless. Makes me wish they packaged this stuff in small tubes, like the Parbond or Acryl-R.

I am a sikaflex distributor and I can tell you that we make sure the tip is full, then let it tack up before you put it in a sealed plastic bag and then into the freezer. We also store full tubes that way on occasion and that can extend the life for more than 1 year. Hopefully, this will help some. Bob Kren

So it is possible! Thanks Bob!

I shove a fair sized screw in the end of the tube of Vulkem, wrap it cellophane and stuff it in the freezer. Haul it out to thaw the night before you need to use it. It does draw some interesting comments from visiting guests when they need to get some ice BTW it is also a sign of a Vintage Airstream owner in residence

I didn't know you could cold-caulk a trailer!

Thanks for the tip. I have tossed several tubes that have turned into core sample type material. I will have to print this thread out and show it to my wife. She thinks I have a few loose rivets now and when she sees what is sitting next to the Ben & Jerry's........

I filled a syringe (from Vintage Trailer Supply) with Vulcem and then I've used it for small caulking duties. The ring-shank shaft from a bulb rivet fits perfectly in the dispensing end. Jam it deep and pull out with pliers to clear the orifice when you need more.
