Hi,
The Redux / Araldite 420 should be stored in a warm environment [ 20 C to 25 C
] at all times anyway. If it is kept at too low a temp', it will crystalise with
''lemon peel'' looking flakes present, which will not fully mix with the blue
hardener[ the green mix will still have the lemon peel bits floating around.]
If your Redux has gone this way..... put it in a pan of water on the stove, and
simmer whilst you stir, the peel will blend back into the main body of the
adhesive.
Try and have everything at the same temperature, ie the resins and the parts to
be glued , you will have more than an hour at 25 C, to get the parts together.
The time life on the can is very conservative, if the Redux has not been allowed
to freeze, it is good for a year past the ''sell by date''.
Cheers,
Nev.

Subject: Europa-List: Redux pre-warming before use????
Gidday,
Well if all goes well tomorrow I hope to bond in my module. It is winter
here in Aussie, however pretty tame by international standards. I have used
old redux once or twice lately, and it is really thick, I think due to the
OAT being about 10-15 for about 18 hours a day, and 15-20 degrees for the
remainder. So, my question is..........is it wise to attempt to prewarm the
redux, only a little, in my tucker box freezer with built in rheostat
light, or should I just leave it alone? If I leave it alone, and don't
preheat anything, well I will get a longer working life with my redux, and
once on I can then raise the temperature of the workshop to about
30+degrees C using my air conditioner. I am tempted with this method, but I
will be mixing and applying a coldish redux mix. Chemically I don't really
see a problem for a well mixed batch or two, and then the air conditioner
should accelerate its chemistry in situ. Any comments much anticipated, and
will be appreciated..
