I have an almost half full bottle of 70% isopropyl alcohol that I use to clean my heatsinks...the bottle's expiration date was 2007...would I still be able to use it to clean my CPU heatsink effectively even if the bottle has technically expired?
As far as I know AS5 is only good for a year or so. I believe that it helps if you store it upright so as to help prevent the separation of the compounds. Probably better to toss it if it's that old.Sorry to hijack your thread(seems like your question has been answered ), but does anyone know if AS5 have a expiration date? I found a tube underneath my desk from probably god knows what year.
How can you tell if it is separated? I have some AS5 that is 3 years old and its still gray and gooey, like normal AS5.eh, I use some that is 3 years old, and have some AS3 that is over 5 I use for ramsinks. It will seperate, just pull the plunger out of the back and remix with a toothpick. If left capped it will not go "bad" just seperate like oil and water salad dressing. If left open it will dry out and be unusable.
