I have a batch of Redux with an expiry date 1998 (so about 12 yrs old).
Not sure why I keep it but do test samples from time to time and apart
---From the emerald green now being more of a grey green it sets as hard as
ever. The mix goes off just fine with no sticky residue. Using a hammer
to separate the bond always ends up with the components breaking rather
than the Redux.
Probably OK as a general adhesive but wouldnt risk it on anything
structural.
If you had an out of date batch and only needed a couple of small jobs
needing Redux it might be worth speaking with Europa. On the non
structural bonds (eg: bedding in bolt heads) flox/ resin is often an
acceptable substitute but check with Europa first.
Its a pity the factory cant supply smaller quantities for repair
purposes. Maybe something the Europa club would be willing to look at.
It would be possible to split a 2kg tin into 200 or 500 g batches.
Just a thought.

I have been using the A420 I got with the kit in about 1966 and
believe the conponents are long lasting - but now that you have spoken I
will run at test before next use.

Yes i did that with mine, but the joints i did all came apart by
hand. Dont know but i think that qualifies as a FAIL
I just use it for fixing bits around the house now, plenty for that

I and others have mentioned this before on this site about
expiration dates on the Redux. Alot of that is due to how long they
want to keep records and liability. If you are concerned about the
suitability of the material concerning its expriation date make a test
coupon. Make a lap sample of the thickness or number of plies of
fiberglass etc that you are anticipating to bond in service and do a
destructive test. If the fibereglass breaks or tears before the bond
separates you can reasonably be assured your material is still good.

Roger, and other Europa Builders in need of Redux also known
as Araldite 420 or Epibond 420 A/B.
I order Redux in cases direct through my long time distributor
TAPE. As there is no other acceptable substitute for Redux, for the
Europa and as a result I am still buying it in bulk and shipping it. I
have looked for substitutes, and many epoxies are as strong, but none as
ductile or willing to be used in aircraft.
I have been informed by my US distributor of Epibond 420 A/B
(Redux) that the manufacturer, Huntsman Products in California, has
restructured their pricing and packaging. I have been in contact with
my distributor and Huntsman over the last four months trying to resolve
the issue. Gladly, Huntsman has at least changed their policy and have
agreed to distribute Epibond 420 in 6 quart cases again. Unfortunately,
Huntsman has nearly doubled the price per case with no significant bulk
discounts available for multiple cases. I've researched importing
fresh Redux from overseas and it is slightly more costly due to the weak
dollar and high shipping/hazardous fees.
If I order soon, and I can still combine with other
distributors I can get 6 quarts for about $280 a quart plus shipping to
you (typically $20). Yes, I know that is $120 more than last year.
Airbus is the primary user so if anyone knows someone at Airbus that can
steal you some and smuggle it into the states, we are stuck with some
pretty ugly prices.
Delivery is 30-45 days to me so it will all be a fresh batch.
Shelf life is a year opened or unopened but usually good for at least
two if unopened.
I have tentative orders for 2-3 quarts so far. I need three
others.

Everyone,
Has anyone been able to source Araldite 420 and Araldite
2102 (rapid epoxy) in the US or Canada? If you have, can you forward me
their contact information.
The stuff from my partially completed kit that I have
purchased has expired. The stuff I believe is classified as hazardous
material for shipping and I'm in Canada so I'll need to find out if the
vendor can ship it here too.
OR
Is there an "approved" alternative that can be used that is
readily available in US or Canada?
Thanks,
Roger Lowe
