CA Glue allergy - alternatives?
Apparently some 5% of folk are allergic to CA glue. I’m one of them and its a pain! Even short exposure brings on sneezing, blocked runny nose and asthma type wheezing. Problem is, the type of work I do necessitates the use of a quick grabbing superglue to hold the pieces together during multiple castings.
Any suggestions greatly appreciated. I’ve just opened a shop in Bowral and am madly producing pieces. At the moment I feel like death warmed up due to the CA glue!
Cheers
Phil

Have you tried the odourless type ? I am not sensitised to CA despite using plenty of it, but I hate the smell of the regular stuff, I mainly use it for a pen finish, and prefer the thin for that, which GPW don’t stock unfortunately, so I source it on ebay, but the thick that they do stock might suit you. It is more expensive than the regular stuff, but I reckon the BSI Super Gold is the Rolls Royce of CA’s.
Might be worth a look at, if you want to continue using CA.

Be very careful, sounds like you're on a dangerous path. Your immune system is attacking/reacting to so-called neoantigens that are formed when the chemically reactive molecules in the CA react with your innate molecules, particularly proteins. Could also precipitate other types of autoimmune diseases.
Some examples:

If you choose to use epoxies be aware that they too can cause allergic type reactions. Also beware of polyester body fillers such as Bondo, other two-part adhesives and coatings. Stay well clear of anything that contains toluene diisocyanate (and related isocyanates) - found in automotive paints.Innovations are those useful things that, by dint of chance, manage to survive the stupidity and destructive tendencies inherent in human nature.

If you are allergic to one type of glue chances are you could already be allergic to a bunch of others
Instead of testing your allergy to these glues I'd go straight to a more permanent solution for any glue/solvent and that would be fixed to use a small dust extractor that vents outside.
Make up a basic fume hood cabinet out of ply or MDF, and attach the DC and away you go.

Yep, I already use an external extraction and always wear a mask. Some of the work requires detail attention which makes it hard not to get some exposure. The aim is to use a less toxic glue in combination with the extractor & mask. Low VOC CA may be an answer? One things for sure though its expensive so I won’t be using too much at a time!!!

You might consider some good chemical resistant gloves too. Check with the manufacturer of the adhesives to see what they recommend first.

A mask is not going to do much unless unless it incorporates carbon/charcoal filters and should preferably be of a full face air wash variety because the vapours are easily absorbed by eyes and skin. The air from such a mask does not need to be filtered if it is drawn from a source well away from the vapours.
I'd be interested to hear/see more about your extraction as I might be able to make suggestions for improvement.

Thanks Rob, I’ve been using dispoable nitrile mechanics gloves. I thought they’d be sufficient. Evidently not!
The message I’m hearing is to stay well away from CA’s and handle other glues/resins with caution.
It does concern me that other folk, because they don’t have an obvious reaction to CA’s are assuming that they must be OK and so don’t need to take care. In reality that’s probably not the case.
I remember years ago being told by a counsellor about alchoholics. She said that often they are folk with very effective livers - that worked so well that the individual didn’t get a hangover. So they assumed “no problem” and kept on enjoying high intakes of alchohol without concern. Until their livers suddenly failed.
Same could be considered about exposure to chemicals and dust. Sometimes its best to have a reaction as it will ensure greater levels of respect and care - thus avoiding a surprise major and potentially very serious reaction down the track.
Cheers

I have a full face mask with an Adflow belt mounted filter. Its a great unit though cumbersome so I tend not to use it for quick glue ups. Which of course is exactly when I should be using it.
My extractor is nothing flash - the hose from a 3hp dust extractor hanging directly above the work area. A bell mouth would certainly improve the effectiveness, as would a purpose built box. On balance though I think your timely reminder on using my full face mask is the best option (in conjunction with extraction and a non CA glue).
Cheers
