Abstract: Coatable urea-aldehyde binder precursor compositions including a urea-aldehyde resin and a cocatalyst yield more consistent quality coated abrasives. In addition, the compositions have longer pot life and allow curing at lower temperatures. The urea-aldehyde resins have an aldehyde/urea ratio of at least about 1.0, more preferably ranging from about 1.0 to about 2.0, and a free aldehyde content ranging from about 0.1 to about 3.0 weight percent based on weight of total aldehyde. The cocatalyst consists essentially of a Lewis acid and a salt selected from the group consisting of ammonium ion salts and organic amine salts. Methods of making coated and other abrasive articles using the compositions are also described.

Abstract: Slurries and binder precursor dispersions suitable for use in producing abrasive articles are presented. slurries comprise a polymerizable resin which is preferably addition polymerizable, abrasive particles, and modifying particles, wherein the modifying particles are present in an amount sufficient to reduce the viscosity of the slurry. Abrasive articles incorporating cured versions of the slurries and dispersions are presented, as well as methods of making the articles and of reducing sedimentation rate of mineral particles (abrasive or filler).

Abstract: A composite abrasive filament, including at least one preformed core at least partially coated with a hardened, abrasive-filled thermoplastic elastomer, exhibits increased abrading life over previously known abrasive filaments. Also disclosed are methods of making such filaments and using such filaments in article form to abrade a variety of workpieces.
