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.
