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, a nanoparticle binder, a sulfosuccinate, and a crosslinking, wherein the abrasive aggregates are dispersed within a polymer resin coating comprising a mixture of copolyester resin. The coated abrasive product is capable of finishing coated surfaces and repairing defects in coated surfaces, including surfaces coated with automotive primers, paints, clear coats, and combinations thereof.
