We are currently using Buehler Sampl-Kwik for our coupon mounting.
However, due to cost issues we are looking at alternative compounds.

I've seen acrylics, polyesters, and epoxies.  The epoxies have very long
cure times and have eleminated them from consideration.

We grind both by hand and on a Nelson-Zimmer system.

What compounds do you use and why?

Are acrylics preferred over polyesters?

Any information would be greatly appreciated.

Thanks for your time.
