摘要: Erodable agglomerates containing individual abrasive grains, a binder and matrix material selected from the group consisting of pulp suitable for making paper derivatives thereof, wood flour, vermiculate. The are useful coated abrasives bonded abrasives. Abrasive products provide higher stock removal than bearing single layer since erodable character allows sloughing off spent grains during abrading operations exposing new to workpiece. invention also provides method preparing this invention.
