Araldite - 'new improved'.

[Orcade-Ian]

Am I missing something?
I have been using Araldite since I was an apprentice in the Aircraft industry in the 1960's.  In those days it was in 2 separate tubes and equal amounts were used - simple!  Then a new system was introduced to dispense the two parts equally, which took out any possibility of error - a great improvement.  Unfortunately, this system has been 'improved' yet again with 2 only nozzles with mixing chambers, which are then left full of unused and unusable product.  Am I missing something, or am I now expected to use the whole package with only 2 applications?  I have always just dispensed the required amount for the job.  Perhaps they are following the Colman's Mustard model who made their fortune, not from what people consumed but what was always left at the edge of the plate!!

Yes,

Effectively they become single use  dispenser

Massively increasing the cost to the user

Possibly try other epoxy products with better application

I think Gorilla works OK

What was wrong with two sperate tubes? BH!

[kent400]

JB weld is still in two tubes but there seems only a few who stock that now. However can be found 'online'

[Bryanj]

What about the rabid version?

Is it only me that is worried about the araldite being used in the aircraft industry 
Please expand on that Ian

Bryan, I only ever tried the 'rabid' version once and was hugely disappointed with the result.  I had left the factory by then but made a couple of specimens for tensile testing and a mate, still at the factory, tested them on the Denison machine - not terribly scientific but I only used the standard version after that test - nuff said!

Just missed that Paul,
Yes, used extensively in Aircraft - we worked closely with Ciba-Geigy who developed it and it was thoroughly tested, I can confirm!  One problem when joining materials with bolts and rivets is that they can suffer from 'fretting' where tiny amounts of movement can take place with vibration and hot/cold cycles.  Interfacing the joints with Araldite prolonged the service life of those vulnerable parts.  Don't worry, the wings and wheels are bolted on!

At present, the company that made Araldite, and the rabid version is supplying the adhesive to bond the wood to build a new Mosquito,

And the CAA is happy with the quality

This is what I use. OK it's expensive buy you get 500g and it  that lasts you for ages and ages and it's proper epoxy with great mechanical & electrical properties.
I mix it with powdered aluminium, talc, powdered ceramic, powdered glass, wood dust etc and use it on everything.

It does take overnight to cure though at room temperature. My top-tip is, if you mix too much to use at the time,  then put it in a freezer and it will last for at least a month.

Thanks for that Ash,
Over the years I have found that anything supplied by RS (I remember when they were Radio Spares!) is of top quality and properly evaluated - as you say, not cheap but you'll know it works.  I like the idea of storing excess in the freezer - I'm also from Yorkshire!
Thanks also for the PM - no rush though,
Ian

I have some of that Ash for the coil fix

Used Araldite AV121 for bonding small motor metallic parts at an Aerospace company that I worked for in the 1980's
Araldite make a wide range of adhesives for different applications...the longer the cure time, gave a better result.
