Abstract
A coated abrasive product comprising a backing bearing on at least one major surface thereof a make coat, a multiplicity of erodable agglomerates comprising a resinous binder and at least one inorganic filler material adhered to said make coat, a multiplicity of individual premium abrasive grains adhered to said make coat and disposed between said erodable agglomerates, a multiplicity of individual premium abrasive grains overlying said erodable agglomerates, and a size coat overlying said individual premium abrasive grains, said erodable agglomerates, and said make coat. The coated abrasive products of this invention abrade faster and endure longer than coated abrasive products using individual conventional abrasive grains in place of erodable agglomerates.
