Abstract: According to various embodiment of the present disclosure, a bonded abrasive article precursor includes a curable composition. The curable composition includes a curative component. The curable composition further includes one or more resins. The curable composition further includes a plurality of shaped abrasive particles. The curable composition is curable in an amount of time in a range of from about 0.1 minutes to about 20 minutes at a temperature of about 25° C. to about 160° C.

Abstract: A method for manufacturing a bonded abrasive article is presented. The method includes preparing a bondable abrasive composition including abrasive particles, a binder medium and an environmentally benign pore inducing material. The environmentally benign pore inducing material is nonflammable. The method also includes forming a precursor abrasive structure from the bondable abrasive composition. The method also includes removing the pore inducing material from the precursor abrasive structure to provide a porous precursor abrasive structure. The method also includes processing the porous precursor abrasive structure to provide a bonded abrasive article.

Abstract: Coatable compositions contain metal-(meth)acrylate hybrid materials that when cured form a metal-polymer hybrid layer with a relatively high refractive index. The curable metal-(meth)acrylate hybrid composition includes a photoinitiator, a polyoxometalate and either a hydroxyl-functional (meth)acrylate or a mixture of hydroxyl-functional (meth)acrylate and aromatic (meth)acrylate. The printable, solvent-free composition, upon curing forms a metal-polymer hybrid layer that is optically transparent and has a refractive index of at least 1.52.
