Abstract
A coated abrasive product has abrasive particles secured to a flexible backing by maker and size coats, each abrasive particle consisting essentially of an agglomerate of fine abrasive grains having an average diameter less than about 200 microns and an inorganic, brittle, matrix. The volume percent of the matrix solids in each agglomerate is from 45 to 75% of the total solids volume of the agglomerate. The agglomerates have an irregular surface permitting a bond to the maker and size coats which is stronger than the crush strength of the agglomerates to permit gradual wearing down of the agglomerates during grinding by gradual removal of dulled abrasive grains from the agglomerates.
