Abstract
A coated abrasive product 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, wherein the abrasive aggregates are dispersed within a polymer resin coating, and wherein the coated abrasive product is capable of superfinishing a metal surface having an initial Ra in the range of about 1.5 micro inches to about 12.5 micro inches prior to application of the coated abrasive product and after application the surface has an Ra of less than 1.0 micro inch.
Claims15
A coated abrasive product comprising:
- a backing;
- and
- an abrasive composition,
- wherein the abrasive composition comprises
- polymeric resin,
- abrasive aggregates,
- a crosslinking agent,
- a thixotropic agent, and
- 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 and a nanoparticle binder, and
- wherein the abrasive composition is applied to the backing, and
- wherein the ration of polymeric resin to crosslinking agent ranges from about 9.5:1 to about 12.5:1.
