Abrasive products and methods for finishing surfaces

摘要

An engineered coated abrasive product having a three dimensional pattern of abrasive structures formed by embossing an abrasive slurry formulation that was first surface coated with a functional powder, wherein the abrasive slurry includes green, unfired abrasive aggregates having a generally spheroidal or toroidal shape, the aggregates formed from a composition comprising abrasive grit particles and a nanoparticle binder. The coated abrasive product is capable of finishing and repairing defects in surfaces, including coated surfaces.

1. An engineered coated abrasive product comprising:
a backing; a cured abrasive composition, and functional powder, wherein the cured abrasive composition comprises
cured polymeric resin, andabrasive aggregates dispersed within the cured polymeric resin, wherein the abrasive aggregates are green, unfired and have a generally spheroidal or toroidal shape and are formed from a composition comprising abrasive grit particles dispersed in a nanoparticle binder, wherein the cured abrasive composition is disposed on the backing, wherein the functional powder is disposed on the surface of the cured abrasive composition, wherein the functional powder comprises abrasive aggregates that are green, unfired and have a generally spheroidal or toroidal shape and are formed from a composition comprising abrasive grit particles dispersed in a nanoparticle binder, wherein the surface of the abrasive composition is embossed with a pattern, and wherein the total amount of cured polymeric resin and the total amount of abrasive aggregates are present in a ratio ranging from 4.0:1.0 to 0.8:1.0.
