Hi just got a new project sitting on the table. The owner called me to tell me that he found 4 cartriges of hysol but the expiration date is 2007. It's safe to use them or better get a new batch? I try the search option with no great results about expiration dates. Thanks

Alex, some epoxy's can go beyond the expired life, but that depends on the conditions how it was stored. Your best bet would to test before use...

You know what Hysol is going to say...They cannot guarantee the quality of the adhesive past the expiration date...Buy some more from us today...Blah blah blah.....

I would do like BirdofpreY suggests...Try it and see if it cures OK...For me, mixing by hand works best....Less waste and this ensures a complete cure....I hardly never use the nozzles except where I have a tight place to get to...

FWIW, Hysol doesn't recommend using the short nozzles due to the possibility of an incomplete cure.....

Mix a batch and see how hard it gets, May be excellent for R/C, but not approved for NACA.

Entirely not true! Loctite does not suggest the 3" swirl tips, the 3" ladder tips we offer are the tips recommended by Loctite

Todd...I called Hysol and was told by one of their techs to absolutely not to use the short nozzles....True, LocTite does sell the tips and I was told that they don't recommend their use with 9462....Oh well...Call on different days and get different answers....

I'm not the only one that has noticed incomplete/slower curing using the short nozzles...I've discussed this with several other modelers, including professional builders such as Tom Robertson...And, I've done my own tests and have noticed that it takes noticeably longer for 9462 to cure when squirted through the short nozzles vs the longer ones...Just my experiences...Your mileage may vary.....

Ok guys just off the phone with Henkel CS. Guess what? You won Kevin! No matter is you mix it and test it, we can not guarantee the quality life of the product. Blah,blah....

I know the owner of the plane I laid on the work table is following this thread. Now you know what you have to do. ORDER THE DARN HYSOL!!!!! [sm=spinnyeyes.gif] I only got half tube left hide somewhere.

Store your Hysol in the refrigerator and it will practically last forever. I'm using some now from 2007 that I kept refrigerated and it works fine. Still agree with the suggestion to try a sample before using in a critical location.

Thanks Graig for your comments on your 2007 batch. I agree and will test it before throw them away. Why I didn't think of that for storage the hysol when I'm used to store my CA in the refrigerator. My newest batch will go that way also.

Jose you still have a change to save yours. But order a few tubes just in case. I will start using mine in your project to speed up a bit. And I will need more for the big one which is next.

I have recently used my last tube that I bought back in 2006, out of 2 cases of 10 I ordered and stored in the refrigerator at about 38 F.

I often notice that when I take a chilled tube out, the white resin, not the hardener, has clumps in it. I found that if I heat a pan of water to about 130 F and drop it in for about 15 minutes all the clumps disappear and it is good to go.

I also get impatient waiting for it to set, so I warm mine up to faucet hot water temp, about 120 F before use. It does run a little bit more at that temp, but not much.
After I get the parts stabilized with wood blocks and tape, I aim a simple 60 watt flood lamp on my shop gooseneck. That way initial setup can be accelerated to about 6 hours rather than 18-24 hrs. It does not get brittle as long as you keep the temp below 140 F according to Loctite literature. I check my temps with my IR temp gun.

I have found no problems with setup using the short ladder type nozzles. My buddy buys them bulk.....3M EPX Applicator Mixing Nozzle #9171....they have a gold color ladder rather than the green ones BVM sells.

I have been told that you can "relife" Hysol by soaking the tube in 40 deg C water until it cools.
