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.

Production of patterned abrasive surfaces

Coated abrasives suitable for very fine abrading applications can be obtained by depositing formulations comprising abrasive grits, fillers, grinding aid, additives and a binder resin and in patterns on a surface using a rotogravure technique providing the viscosity is controlled such that the formulation deposited does not lose its shape prior to cure.

Rotogravure process for production of patterned abrasive surfaces

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 in the form of a structured abrasive and then adhering to the surface of the structured abrasive a functional powder.
