Is Araldite safe to use on the inside of a carbon frame?
Using it to stick a Datatag inside the frame.
Should be fine, it's epoxy just like the resin that's holding it together. Little rub with fine wet and dry, wipe away dust with a bit of ipa (other gentle, none residue degreasers available) on a cloth and off you go.
Not sure, but I know double bubble hardman epoxy works well.
You can pick up a single use sachet for pence from eBay
I've used it to repair frames...so yeah, I suspect it'd be ok 🙂
Cheers all.
I'd say a big fat NO. Araldite is not flexible - it dries rock hard - very strong and brittle. If there is any flex in the area you are applying it will be a straight fight between how strong the araldite is vs. the parent carbon frame material if there is any flex or deflection in that area. My money is on the araldite. All epoxy is NOT the same just like all Steel is not the same or all Aluminium Alloy's are not the same etc.
What about the epoxy's used to repair surfboards?
I'm just talking about a small blob to hold the tag on.
It's about the size of a grain of rice and going in either the headtube or BB shell. I really don't think there'll be much flex inside either of those.
I've used it to glue headset inserts , and suspension pivots inserts back into a carbon frame when they came unbonded. No Ill effects 2 years after gluing.
In that case then it'll be fine. I thought you were thinking about applying it to repair part of the frame or something. I've used it in the past on things that have some flex in them or under compressive load and it's not ended well.
