A coated abrasive disc has a backing comprising a synthetic woven fabric
having a first major surface with a presize disposed thereon and a second
major surface opposite the first major surface and having a backsize
disposed thereon. The presize comprises a reaction product of a curable
presize precursor comprising: at least one epoxy resin prepared by
reaction of epichlorohydrin with at least one of bisphenol A or bisphenol
F, polyfunctional (meth)acrylate, novolac resin, imidazole epoxy cure
catalyst, dicyandiamide, and a photoinitiator. A glass woven fabric
permeated with an at least partially crosslinked saturant is secured to
the second major surface by a thermoplastic laminating adhesive disposed
between the second major surface of the synthetic woven fabric and the
glass woven fabric. A method of making the same is also disclosed.
