Can I use Sikaflex past its "use by" date?

[John Collier]

I used my old Sika to glue some alum map pockets on the interior, leading edge of the skirt. It's holding fine, but it certainly didn't cure as well as the new Sika.

So...I agree with your decision...however - you might find some non-critical projects for that old Sika!

I'll give you $10 for it. And shipping!

-8A. There were 2 basic steps in the Sika canopy process - 1) Structual application to actually attach the canopy; 2) Cosmetic application to make it look nice.

I'd buy new stuff for (1) but use the expired stuff for (2).

A question I asked before on this forum but should be periodically addressed: Has anyone had any problems with the structural integrity of their Sika canopy install as the timeline progresses? I'm 2 years since install and 90 flight hours since first flight in Apr 2011 with no problems.

Sealant expirition dates are a racket,,,,,,,, Went thru this when at the airlines and nobody could tell us what the dates were based on!

Keep them cool and dry and they last way longer than their posted dates. If they mix and cure properly they are good to go. Glad shops get rid of them when they are expired... saved me a lot of money!
