发明名称 COATED ABRASIVE DISC AND METHOD OF MAKING THE SAME
摘要 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.
