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.
Claims17
A process for the production of a coated abrasive comprising a pattern of abrasive/binder composites adhered to a backing material, said process comprising:
- a) depositing a slurry formulation comprising an abrasive and a curable resin binder on a substrate in a continuous or patterned manner,
- (b) treating the deposited formulation to render at least the surface portion of the formulation plastic but non-flowing;
- (c) thereafter embossing a pattern upon the binder/abrasive formulation;
- and subsequently
- (d) curing the binder component of the formulation to retain said pattern.
