Discrete particles that include a polymeric material and articles formed therefrom

An abrasive article is provided that includes a tie coat which improves adhesion between an abrasive layer and a backing in the abrasive article. The tie coat is preferably formed from a tie coat precursor comprising a sulfopoly(ester-urethane) component comprising in its backbone at least one non-terminal arylene or alkylene group comprising a pendant sulfonic acid group or salt thereof having the formula: ##STR1## wherein R is a trivalent aliphatic or aromatic group and M is a cation, said aliphatic or aromatic group being bonded directly to ester groups and wherein the polymer is terminated by at least one hydrolyzable silyl group. Preferably, the abrasive article is a structured abrasive article. Also provided is a method for making an abrasive article.

Abrasive article with tie coat and method

An abrasive article is provided that includes a bond system formed from a binder precursor and about 15% by weight or less of a wax-containing modifier. An abrasive article that includes the bond system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a bond system formed from a composition containing substantially no wax-containing modifier.

Abrasive articles including an antiloading composition

Abrasive articles made using a coatable, addition polymerizable binder precursor composition are described, as well as methods of making same. The compositions comprise a reactive diluent compound and preferably an addition polymerizable resin, the reactive diluent being an organic compound selected to be especially effective in solubilizing aminoplast resins.

Thermosetting binder for an abrasive article

A method for preparing a coated abrasive article wherein the a plurality of abrasive grains are applied to a make coat such that the abrasive grains are substantially a mono-layer. The make coat precursor is a pressure-sensitive adhesive-like or pressure-sensitive adhesive. The make coat precursor is partially cured to approximate a pressure-sensitive adhesive-like layer or when fully cured is a pressure-sensitive adhesive. The make coat precursor has sufficient 'tack' to hold the abrasive grains during the application and curing of the size coat, resulting in a substantially monolayer of abrasive grains.
