Be just as cautious with all adhesives , plastics, resins paints and woods etc....always work in good ventilation and dont breathe the dust, most things are bad for you breathed in.
There is no cyanide in or around the manufacture of cyanoacrylate glues, the similarity is they also contain Carbon and Nitrogen....as do many things... thats about it....the nitrile group
The confusion is mainly caused by people who have been involved with spraying cars using `2 pack` paints using isocyanates as catylists thse are in polyurthanes and can easily release cyanide especiallay if burnt chemicals such as methyl isocyanate , highly toxic isocyanates ( 2 pack catylist and foaming wood glues ) are nothing to do with cyanoacrylate glues
You will not release cyanide from heating cyano glue in any normal way, it does not happen it needs to be actually burnt under the exact conditions in a flame for even any slight chance of tiny amounts of cyanide production it basically can not happen unless you decided to make it happen!
What you can smell is purely cyanoacrylate....its not good to breathe it in....its not nice....it causes sinus irritation so the irritation can cause sinusitis and headaches sore eyes etc
Acrylic polymers such as perspex , cyanoacrylate etc will on heating vapourise to create th liquid monomr thy wre formd from , example PMMA ( poly-methyl methacrylate / perspex ) can depolymerise to methyl methacrylate vapour and poly ethyl-2- cyanoacrylate ( solid superglue ) will depolymerise to create cyanoacrylate gas that you could....( but you can not...) collect condense with a cool surface and put back in a bottle to reuse.... ( if you could keep it from setting first.... )
Three is no more chance of cyanide gas release in sanding / machining cyanoacrylate than there is in getting hydrogen and oxygen sanding a bath of water.
Chips....they contain cyanide.... cooking oils after heating up contain acrylonitrile (
CH₂CHCN )The nitrile group is the group contain cyanide, -CN
Cyanoacrylate ( ethyl ) the normal one to have is
C6H7NO2Odourlss cyano is a heavier molecule such as Octyl Cyanoacrylate C12H19NO2 If cyanide was produced by cyanoacrylate in any way it would not and could not be licenced for production and sale to the public
Not that you should breath them in.... as with ALL adhesives and paints....even waterbased ones ( and even non adhesive items such as salt flour wood, and sugar! ) you should keep them off your skin and not breath them in as a liquid gas or dust
Fuming of fingerprints with cyano is done by heating liquid gel CA glue,
When we manufacture the monomer if you open the collection receiver tank too soon the vapour pours out...thick white clouds of steam and if you place your hand in it it condenses liquid CA on your hand that just drips off , just like water vapour would this is what they are doing with the fingerprints it evaporates and condenses on the prints and soaks into them.
This is a patent that is very similar to manufacture today, not how its done exactly but the basic chemicals are just about the same ,just purer , more stable and better production levels and many additives
