Beschreibung
Zusammenfassung:	A coated abrasive article comprises a backing, optionally having at least one of a presize layer, a saturant, and a backsize layer thereon; and an abrasive layer adjacent and secured to the fabric backing. The abrasive layer may comprise a make layer, a size layer, and abrasive particles, or the abrasive particles may be dispersed in a binder. At least one of the make layer or presize layer comprises a reaction product of a binder precursor comprising from 45 to 75 percent by weight of resole phenolic resin, from 5 to 40 percent by weight of polyepoxide, from 1 to 20 percent by weight of polyfunctional (meth)acrylate, and an effective amount of photoinitiator to free-radically B-stage the binder precursor. Methods of making and using the coated abrasive article are also disclosed.
