Lapping and Polishing Slurries


Oil-based diamond suspension

Oil-based ready-to-use diamond suspension for highest performance in lapping and polishing of sapphire, ceramics and metals. Tailored additives provide maximum material removal rate (MRR) while extending the process window for best performance. SPO diamond suspensions feature up to 25 % higher material removal rate compared to other oil suspensions. Novel stabilizers prevent precipitation of the diamond particles and thus help to enhance process stability. For application in machines with stirring units the suspension is available without stabilizers.
