I'm new to the resin world but it looks fun and so I've joined you guys to ask you some questions to better my projects.
Right now I'm casting some doors for customizing my vape gear end I am using the classic E-30 clear resin by prochima since on the web everybody seem to be pleased with their results however I'm having some problems with it. My biggest issue is that it bends even if I let it cure for like 3 days it bends.
Initially I tought it was because of the coloring I was using (mainly nail polish and oil painting in little quantities) But then i tried to make a clear cast and it was smooth as well so I guess that have not that big influence
now I'm considering as an hypothesis that is just because I do cast which are like 3mm thin could it be the case ? Or is it because it stays near the atomizer of my mod which is hot? Or it might be bothI tell ya guys I've mixed at 60:100 as of instructions even 80:100 ( tought it would become harder 
) Any suggestions ? I saw this resin online https://shop.smooth-on.com/epoxacast-655-ht that is aluminum filled but I didn't have the chance to see any casts made with it so I don't know, also I'm in Italy so I don't know if it's available
Thanks to anyone that would have the patience to help me out
Have a good one
