Chemal is a polishing cloth for use on a magnetic backing disc, designed for the final chemical/mechanical polishing of all materials. It is a synthetic foam cloth specifically designed for final polishing with oxide suspensions. Chemal can be used with both acidic and alkaline oxide suspensions, as well as neutral suspensions. This includes fumed silicon dioxide suspensions, colloidal silicon dioxide suspensions and alumina suspensions. It is recommended to use low forces of 15N on a 30mm sample. For best results it is advisable to use plenty of suspension to avoid exhaustion.
