Abstract
Erodable agglomerates containing individual abrasive grains disposed in an erodable matrix comprising hollow bodies and a binder. The agglomerates are useful for coated abrasives and bonded abrasives. Abrasive products containing the agglomerates provide higher stock removal than abrasive products bearing a single layer of abrasive grains, since the erodable character of the agglomerates allows the sloughing off of spent individual abrasive grains during abrading operations and the exposing of new abrasive grains to the workpiece. The invention also provides a method of preparing the agglomerates of this invention.
Claims22
An abrasive article comprising erodable agglomerates comprising a multiplicity of individual grains of abrasive mineral randomly distributed in an erodable matrix comprising very small, erodable, crush resistant hollow bodies and an erodable binder.
Erodable agglomerate suitable for an abrasive product comprising a multiplicity of individual grains of abrasive mineral disposed in an erodable matrix comprising hollow bodies and a binder.
