  • Coated substrate with energy curable cyanate resin
    Patent number: 6709738
    Abstract: Provided is a treated substrate comprising a backing material coated with a resin derived from a curable precursor resin, which comprises an energy-curable component comprising a cyanate ester resin and a curing agent. Also provided is an abrasive article comprising a plurality of abrasive particles incorporated into a bond system, wherein the bond system comprises a make resin derived from a first curable precursor resin, which comprises a first curable component comprising a cyanate ester resin and a first curing agent, and wherein the bond system additionally comprises a size resin derived from a second curable precursor resin, which comprises a second curable component comprising a cyanate ester resin and a second curing agent. Also provided are methods of making a treated substrate and an abrasive article.
