Abrasive material having a polycarbodiimide and polyurethane resin binder |
| abstract |
An abrasive material which comprises abrasive grains and a polycarbodiimide and polyurethane resin as the binder for the abrasive grains and a method of preparation thereof are disclosed. The polycarbodiimide and polyurethane resin is prepared by reacting a polyisocyanate and a polyol in the presence of a catalyst. The resin has a specified amount of carbodiimide bonding and urethane bonding. |
