Looks like interesting stuff... If it only wasn't BLUE! I found them on the web at http://www.rentooling.com
: Hi Paul,

: I mentioned the epoxy filled with carbide on the board a few days ago. We use
: to use it for a surface coat while making master molds that had a metal
: tracer constantly running over them and therefore had to be tough and
: vitally non wearing. On the plus side this epoxy (Ren Plastics RP-3260 )
: was so tough that it would easily destroy a high speed drill bit ( we used
: tungsten drill bits ) but the wear resistance was unbelievable. It could
: wear the rocks down before it wore down. On the down side it is an ugly
: blue (see picture) it is thick and we heated it under lamp to thin it and
: brushed it on. To smooth out sags or ripples after it is applied is very
: hard. Sandpaper hardly touches it and wears out quickly. I would say it is
: 20 time harder then the epoxy plastic we use on our boats. I have not
: found Ren Plastics on the net but I can get the address if anyone might
: want to experiment. Meyer Plastics Incs. , 8343 Clinton Park Drive, Ft.
: Wayne, IN ( also in Indianapolis and I think on the net) is another
: pattern shop supplier that would probably have something similar, but
: whether it would have the same amount of carbide in it or not, I don’t
: know.
