good in epoxy?
HEY CAN SOMEONE EXPLAIN: 1) How epoxy PUTTIES are made? Does the body mostly consist of just epoxy + talcum powder mixed into each of part a and part b? can I make my own putty from a low viscosity epoxy?
2) Is epoxy the strongest material in the world? Can someone disuss the possible achievable tensile strengths, what allows for these strengths because I often see tensile strength quoted
3) Is epoxy often utilized in ICF (insulated concrete form) work for building homes to increase the strength of concrete and prevent the steel rods from corroding or is polyester used?
4) I think the section about gel coats needs clarification. It says that polyurethane can coat over epoxy and then it says it has poor adhesion. Which is it? Also, is it possible to use oil paint on top of epoxy (ie are there adhesion issues?)
5) Can someone please add a section about how epoxy can be used in wood rot applications by applying borax first?
6) Is silane ever added to epoxy?
7) It is confusing so who owns the switzerland epoxy plant now?
Thanks. —Preceding unsigned comment added by 86.31.47.199 (talk) 07:28, 22 April 2008 (UTC)

[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?
- Oops, I could've *sworn* I signed this. --Joe Sewell 17:42, 21 November 2005 (UTC)
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).
[edit] Krazy Glue
I Heard Krazy Glue Will Melth Through Epoxy. I Put Krazy Glue On My Surfboard Which Has An Epoxy Covering And It Turned White. It Is One Of The Aviso Boards That Are Made Of Carbon And It Costy Me About $1220 So I'm Pretty Worried About It —The preceding unsigned comment was added by 67.169.154.107 (talk) 23:10:00, August 18, 2007 (UTC)
[edit] Epoxy group
Isn't epoxy also the name of a chemical functional group i.e a chemical can be siad to contain and expoxy (epoxide) group, which is presumably why this compound is so named?
Souldn't this fact be incorporated into this page or a disambigious-type page created? —Preceding unsigned comment added by 80.254.147.68 (talk) 09:47, 27 September 2007 (UTC)
Yes, I think there should be a disambiguation page. One link should come to this page, which should be called Epoxy(adhesive). The other link should go to the Epoxide article. Deepfryer99 (talk) 20:13, 20 March 2008 (UTC)
[edit] temperature service range?
What is the typical temperature service range of the cured adhesive? -69.87.200.177 (talk) 23:38, 29 April 2008 (UTC)
