Resourcinol still good? |
Lead | ||
|
I've got some resourcinol I last used about 1.5 years ago. I covered the resin can with aluminum foil, put it in a ziplock, and then put it on a shelf in
the coolest part of my house. Need to glue up some rods and short of doing a test is there an easy way to be sure the glue is still OK? It still looks a bit
like automatic transmission fluid, there is a little bit of brown tinting up in the can but the resin itself is not very viscous (viscosity like warm varnish)
and looks about like it did when I sealed the can up 18 months ago. Any advice would be appreciated.

I use Resourcinol and I wouldn't trust it, but I *never* keep an open can past 3 months. If it has thickened much, you can be sure it is bad.

Mike,
As far as I can tell it hasn't thickened at all, it is really thin (not viscous). Maybe I should just get a new can it's not that expensive but I hate to throw it away if it's good. |

you could always glue up a test strip and see....

Test it. I used some old reourcinol (8 years) to glue a reel seat on a 80# class salt water trolling rod. That was 20 years ago and there is still no problem.
Lucky? Maybe. Aging of some of the adhesives too conservitive? Probably.
Make a lap joint 1/2" by i/4" and try to break it apart when it is set. I would bet you will find it will be very strong. fishbum |

The instructions on my resorcinol say to disgard once opened within two years.
That said , I have used resorcinol up to five years old with no issues (as long as it isn't too thick !). I suspect the instructions like with food stuffs and their sell by dates etc are on the cautious side. That said if your not happy just throw it out as the cost of some new will be less than the time you have expended to date getting ready for gluing. Paul B |

I chickened out and just got a new can. I bet the stuff was OK but I was in a hurry and I know the new stuff is good for sure.
I do know the 1-year shelf life (unopened) given by DAP is BS, a can can be several years old and be just fine, as long as you don't leave it in a hot garage. Thanks for the help you guys, -John |

What do you guys do with old glues and varnishes? I don't want to throw them in the regular trash.

Get in touch with the local landfill, they'll point you in the right direction. And no, they should not go in the trash.

use it to make a great, flaming heat source to char whatever chunk of meat that needs to be cooked for a fabulous tasting meal...
...seriously speaking, being a VOC laden material termed as a hazardous material
(hazmat)...there are legal rules about getting rid of these types of materials. Most landfills can't just drop them into their waste and have to dispose of
them in a very specific manner, so as suggested, contact them and they will tell you the rules in place at their facility which usually has a cost, definitely
don't put it in the trash...and most waste management companies and landfills have a yearly "HAZMAT DAY" where you are allowed to get rid of all
of your VOC bearing hazmat materials free just by bringing them in and dropping them off....just put them, and any other paints, spray cans, paint strippers
etc, in a bigger collection container and then when that day comes around, take them all to the facility and drop them off...dj
