Re: [CAD_CAM_EDM_DRO]polymer concrete

Hi, well i am no expert but the machine i saw being built they poured the
urethane/concrete like material into the machine once it was at the
customers site. Then final scraping and set-up was done. The material was a
base of Urethane, stone powder and some type of emulsion binder to keep the
viscosity even till it was set-up. The small piece i had didnt bounce when
tossed to the floor but more of a flap-n-thud sound. You really couldnt
damage it with a screwdriver..go to a place where they use those materials
and ask to see how it is used. Maybe they will tell you who's material they
use. cul brian f.
