A method for producing organically bonded abrasive article includes combining
an
abrasive grain component and a phenol-based resin component. The combined components
are molded and thermally cured in an atmosphere that comprises humidity, wherein
the atmosphere contacts the molded components, thereby producing the organically
bonded abrasive grain. The abrasive grain optionally can first be combined with
an organosilicon compound, to form organosilicon-treated abrasive grain, and then
with the phenol-based resin component. In one example, the phenol-based resin is
thermally cured in the presence of steam. Abrasive articles produced by the method
of the invention generally have improved properties under wet grinding conditions.
In one example, an abrasive article produced by the method of the invention includes
ammonia in an amount less than about 50 ppm. In another example, an abrasive grinding
wheel produced by the method of the invention has a strength retention greater
than about 57 percent.
