good in epoxy?
[edit] 1-part epoxy?
Could someone with some knowledge in this area explain, or at least refer to a site, how a 1-part epoxy (no separate hardener, I assume) works?

Some epoxies require a certain heating aspect in order to cure - certain temperature for certain time. In this case, you can mix the two parts together, but they won't cure until the heating has been carried out, or at least they will cure very very slowly. I would guess that this is what a the 1-part epoxy you're talking about is. -chc
Another type of 1-part epoxy is a Powder Coating type known as Fusion Bonded Epoxy (FBE coating). This, as final product, is a one component powder coating. Infact, the powder coating contains the epoxy, hardeners, fillers and extenders, but they all are blend and in a powder form at ambient temperature. Please refere to the article in Wikipedia "Fusion Bonded Epoxy Powder Coatings" for details. I have edited the section "Paint and Coatings" in the main article to incldue FBE coatings in the text.

Does anyone else think the caption below the picture of epoxy curing on a surfboard fin sounds like an advertisement for the mentioned brand of epoxy?
[edit] Epoxy Removal
I believe Epoxy is also used in electronics for security, making the electronic component under a dob of epoxy very difficult to get to and be tampered with. Can anyone else vouch for this? And, how does one remove epoxy? Or is it not possible? Matejhowell 17:39, 31 January 2006 (UTC)
In the pipe coating industry, the applied epoxy coating (rejected during QA/QC) is removed by burn-off at a temperature of 700 to 750° F for about 6 hours in an air circulating oven. Another method of removing epoxy coatings from small aras is by soaking the area in a suitable solvent such as Methyl Ethyl Ketone (MEK) or Xylene. ~~ Penguine_s February 5, 2006
For larger areas, such as in decorative collector's displays of coins or other objects embedded in clear epoxy resins, one will find MEK, Xylene and most organic solvents completely ineffective in dissolution of epoxy. <Ken Forbes April 13, 2006>
Air temperature cured epoxy can be "melted" by applying heat. Michael
[edit] Epoxy Quality
Is there any way to determine the additive that causes one epoxy to harden faster than another? —The preceding unsigned comment was added by 70.184.10.240 (talk) 17:25, 13 February 2007 (UTC).
