Toxicology
According to the German Wikipedia, epoxy is highly toxic and carcinogenic upon skin contact, and a number of industrial institutions are named which therefore issue health regulations regarding it, which is that no material for daily use must be made of more than 0.0002% epoxy. Also it recommends handling epoxy only by means of proper protection, that is full-body protective suits, like hazmat suits, and that simple rubber gloves are not save to handle a substance as hazardous as epoxy.
While here on the English version of the article, epoxy is made out to be just like any other glue. Might this have something to do with the fact that "60% of the Dollar value is dependent on the epoxy industry"? --79.193.56.119 (talk) 02:54, 30 July 2011 (UTC)
- "There are no reports of carcinogenic, mutagenic, teratogenic or reproductive effects to humans..." but you are right about rubber gloves: "PVC gloves, good housekeeping, hand washing before breaks are needed." This is a bit of a simplification as the manufacturing process, rather than the deployment, uses some nasty stuff. 60% of the cost of the product goes to these bulk manufacturers, but why would this introduce any overly favorable editing on the English Wikipedia?

- Afterthought: I've just looked at the German article, for an explanation of "no material for daily use must be made of more than 0.0002% epoxy". What it actually says (or, rather, what the google translate rendition actually says) is that any unconsumed residual of a component, epichlorohydrin, should be less than 0.002% (not 0.0002%). "Under certain circumstances a protective suit may be necessary" (emphasis added). Any help? --Old Moonraker (talk) 09:16, 30 July 2011 (UTC)
- Epoxy resins are not toxic by themselves. They may produce skin itching or allergies (eben very bad ones), so keep it away from your skin. Other epoxy compounds may be toxic, carcinogenic and so on. This is true, e. g. for the above mentioned epichlorohydrin (one of the nasty stuffs used to produce epoxy resins). In addition, some epoxides of low molecular mass are used as a reactive diluent for epoxy resins. These too are usually more dangerous to health than the resins, especially some diluents which were used in former times (phenylglycidyl ether e.g.).

Newer developments like fatty alcohol glycidyl ethers seem to be nearly harmless. --FK1954 (talk) 13:58, 22 August 2013 (UTC)
