Claims9
A coated abrasive comprising a plurality of filamentary abrasive grits adhered to a backing material, the grits having an essentially U-shape with the open ends oriented away from the backing.
A coated abrasive comprising a backing material and, adhered thereto, a plurality of filamentary abrasive grits each being coiled about an axis and aligned with the axes of the coils parallel to a major surface of the backing material.
A process for the production of a coated abrasive comprising:
- a) providing a backing material bearing a layer of an uncured binder material;
- b) depositing a plurality of filamentary abrasive grits each being coiled about an axis on to the layer of binder material such that the coils become at least partially submerged in the layer of binder material with the axes of the coils parallel to a major surface of the backing material;
- and
- c) curing the binder material to produce a coated abrasive.
