Epoxy
Hi,

I have reverted some of your changes to the article Epoxy. This is because they (a) Removed some existing material which already had source citations/references and (b) Replaced it (and added to) with material that was primarily uncited. Although some of the new content may have been useful, it's hard to judge in such a context.

Unfortunately, the images you added will also have to be removed, as they were uploaded to Wikimedia Commons with no evidence that permission had been granted by the copyright owners to use them. (The evidence suggests that you didn't take them yourself despite being labelled "own work").

Commons can only accept images suitable for free use (i.e. licensed under those terms or with no copyright remaining). Wikipedia itself allows some non-free images to be used as "fair use", but a case has to be made justifying their inclusion.

Hope this explains things,
