Abstract

A discrete coated abrasive particle wherein the coating comprises an inner metallic, e.g. nickel, layer and an outer non-metallic protective layer which is preferably a solid resin such as phenolformaldehyde resin is produced by depositing the protective layer on to metal coated particles and the metal coated particles are preferably washed with a cleaning solution immediately prior to the deposition.
