Someone has inserted superglue in the door locks of my car, I was wondering if there is any dissolvent in which I can soak my locks instead of paying some ridiculas amount to install new locks any help would be welcolmed From Jan N.Z
:I did a little googling, and found the following advice over on http://www.howstuffworks.com/question695.htm : "By the way, if you happen to find yourself in a super-sticky situation, a little bit of acetone nail-polish remover helps to unglue fingers." So perhaps squirting a little nail-polish remover into the lock will help. Note, I have never tried this myself, so I make no guarantees. Bryan 06:14 Oct 1, 2002 (UTC)

thread_title:  How to get out of a fix 

message: The current article states "If applied to cotton, cyanoacrylate undergoes an exothermic reaction rapid enough to cause minor burns if spilled on clothing, although this reaction is not powerful enough to be noticeable unless it involves more cyanoacrylate than any non-commercial use would reasonably call for." Isn't this a bit of a contradiction? If it's strong or fast enough to cause minor burns, wouldn't it be noticeable? (Also, a recent accidental encounter with said reaction left no doubt in my mind that it's noticeable, and my painful fingers agree...) Eleraama 05:46, 29 August 2007 (UTC)

I very much doubt the veracity of "Its major polymerization byproduct, acetic acid, is biocompatible. Cyanoacrylates are used in orthopedic surgery to glue metal appliances to bone. They are often used, for example, to glue artificial hip appliances to femurs and pelvic girdles." Acetic acid is a byproduct of acetoxy RTV silicones, not cyanoacrylates (CAs). As CAs have poor moisture resistance, they are probably not used as structural adhesives inside the human body, unless meant to be temporary.
In reviewing some abstracts via Google, it looks like there are some problems with N-butyl-2-cyanoacrylate (NBCA), a new-generation cyanoacrylate derivative, and there are some details on the use of "cyanoacrylate glue applied on both deep and superficial tissues" that seem to be slightly negative on animal testing. I don't know much about the field, so I'm just trying to throw out some info, but I personally doubt anyone's using such adhesives to hold hip appliances to femurs. Harmil 20:53, 31 May 2005 (UTC)

message: Having tried several brands of superglue lately with less than happy results, I have the strong feeling that the product is far weaker than the superglue sold in the 1970s. Back then there were a lot of stories regarding users bonding all their fingers together against the surface to be glued, and having this bond instantly. Is it possible (as I suspect) that the product today has been weakened to avoid this kind of mishap? Is this something that can be documented?  ProhibitOnions  (T) 12:55, 24 September 2006 (UTC)
replies: text: I suspect as much. Despite all the warnings, whenever I end up superglued to myself, I never have any difficuly pulling the bond apart.

message: It is not common to stringed-instrument players to "form protective finger caps" as noted in the article. I'm a guitarist but I've never heard from that. However, cyanoacrylate is used by classic and flamenco guitarists to strengthen the nails, mostly in combination with silk. This practice is discussed widely on forums, and therefore a few "guitar nail kit" products are available on the market.
Also, "stringed-instrument players" could be replaced by "guitarists" if no other stringed-instrument players use it. But that will take a little investigation. (unsigned)
:Some violinists use CA on fingertips for repair of cold-weather skin splits, shredded cuticles, damaged calluses, and so on. The smaller members of the violin family (violin, viola) do not usually lead to the kind of callus formation experienced by many guitarists. I doubt that very many fiddlers need to form a "protective finger cap" which would only get in the way of the sensitive touch it takes. __ 66.189.117.133 (talk) 22:50, 21 June 2010 (UTC)

message: Neosporin is a topical antibiotic ointment.  If it works at all as a solvent or softener for hardened cyanoacrylate glue, then it probably is due to the ointment base, not the antibiotics, and petroleum jelly would work as well and be safer.

Pending resolution of this potentially confusing point, which might be hazardous if someone allergic to neosporin tries to use it to remove the glue from their fingers, I have deleted the sentence saying neosporin is a widely available nontoxic solvent for cyanoacrylate glue.CharlesHBennett (talk) 00:21, 5 January 2010 (UTC)

thread_title:  High temperature 

message: "I worked for Loctite in the R&D and applications development groups. I developed many modifications and pioneered several unique medical apps using cyanoacrylates. Typically for use in the body the type of CA is called N Propyl Cyanacrylate ester. It is triple distilled for both purity and use. Once the cyanoacylate has polymerized it is considered inert. It is a thermoplastic so will melt when heated to typically above 180C. It is a pure monomer system when seen as a clear watery liquid..."
"sorry but CA's do not have any solvent in them.. they are what is called 100% solids adhesives... meaning they are 100% monomer... No solvents whatso ever... what you smell is the monomer evaporating at ambient conditions.. typically they volatilize during thr first minutes of application.. until the surface etc cures or polymerizes... then there is no smell left.. since all the liquid is polymerized to a solid."
How CA Polymerization occurs
"First you need to know that all CA's are stabilized.. with a weak acid to prevent the polymerization from starting..then when a CA is applied to a surface that is or has been in ambient conditions, meaning it has adsorbed moisture from the air. The cyanoacrylate undergoes anionic polymerization in the presence of the weak base, such as adsorbed water on the surface. More simply, when the adhesive contacts a surface, the water present on the surface neutralizes the acidic stabilizer in the adhesive, initiating the polymerization.. this is why you should always exhale a few breaths on the mating surfaces to be bonded with CA's just prior to bonding.. expecially in dry climates like AZ.. This initiation is different from the Free Radical initiation that anaerobic acrylic adhesives use...CA's and Anaerobic acrylic adhesives.. such Loctite thread bonds, retaining compounds, and adhesives are all very reactive adhesive systems and must be stabilized...but just barely... just enough that they stay stable under normal conditions.. then when that stability is pushed over the edge... voila'..polymerization starts and continues to completion..."
This quote is from forums.randi.org/showthread.php?t=48426 -- an enlightening discussion with a Loctite technical expert.
The article should cover CA being pure monomer in tube, no solvent. Stabilized in tube with weak acid. Sets to thermoplastic, melts at 180C.
