kench Posted September 29, 2013 Report Share Posted September 29, 2013 I believe there are many types of casting resin (polyurethane, polyester, acrylic, epoxy...). But I use polyester casting resin to make polishing wheels (to polish glass edges and bevels). I mix cerium oxide powder into the resin, add the hardener and then drop the mixture into the mold and wait overnight. Then I use my lathe to true the wheels. It hardens very good even with a lot of cerium oxide in it and machines very well on the lathe. It seems that it can be sanded easily so I am guessing it should be good for pore filling too. The viscosity of the mixture is like slightly thinned lacquer, so I guess it is enough to fill the pores. 1 Quote Link to comment Share on other sites More sharing options...
