A friction material for a friction facing member useful for transmitting torque includes a backing having a front surface and a rear surface. A plurality of precisely shaped friction composites defining patterned friction coating are attached to the front surface of the backing. The precisely shaped friction composites include a plurality of friction particles dispersed in a binder. In one embodiment, the friction material has an elastic modulus of about 10 dynes/cm or less.

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.

Nonwoven abrasive article and method of making same

A method of preparing a coated abrasive article in which the presence of multiple layers of abrasive grains are minimized. In one variation, the method comprises the steps of: (a) providing a backing; (b) applying a make coat precursor to the backing; (c) partially curing the make coat precursor; (d) applying, preferably by projecting, a plurality of abrasive grains into the partially cured make coat precursor; and (e) completely curing the partially cured make coat precursor. In another variation of this method, a size coat precursor is applied over the abrasive grains and cured make coat, and the size coat precursor is completely cured. In another variation of this method, a size coat precursor is applied over the abrasive grains and the partially cured make coat precursor, and the make coat precursor and the size coat precursor are completely cured. The make coat precursor preferably comprises an unsaturated resin that polymerizes via a free radical polymerization mechanism at the site of .alpha.,.beta.-unsaturation.

Method of making a coated abrasive article

The invention provides a compostable thermoplastic polymer composition comprising a thermoplastic polymer, a transition metal salt selected from cobalt, manganese, copper, cerium, vanadium and iron, and a fatty acid or ester having 10 to 22 carbon atoms providing unsaturated species and free acid. The composition will oxidatively degrade to an embrittled state within at least 14 days at 60.degree. C. and a relative humidity of at least eighty percent.
