Hi,

I'm looking at using some self leveling epoxy resin to apply approx 2mm layer on top of a 10mm steel plate steel 1000x500mm once the resin has cured I am going to then drill and tap the steel and place hiwin linear rails on top. I'm hoping for 0.05mm or as close as I can get flatness. 

Do you think this would be possible? Also will the epoxy have any significant shrinkage? What sort of forces will it crack at? As the linear rails will be bearing considerable force maybe static load of 4000N and with dynamic loads up to maybe 6000N.

If so what kind of epoxy resin would be suggested to be suitable?

Thanks in advance for your help.

Dave.
