  • Production of patterned abrasive surfaces
    Patent number: 5863306
    Abstract: Coated abrasives suitable for very fine abrading applications can be obtained by depositing a layer of a formulation comprising abrasive grits, fillers, grinding aid, additives and a binder resin on a substrate, treating the formulation to increase the viscosity and render it plastic but non-flowing, embossing a suitable pattern on the surface of the layer, and then curing the binder component of the formulation.
    Type: Grant
