A curable emulsion comprises: an oil phase comprising blocked polyisocyanate and curative; and an aqueous phase comprising at least partially neutralized crosslinked copolymer of monomers comprising at least one free-radically polymerizable carboxylic acid and at least one of an alkyl or alkaryl (meth)acrylate. In some embodiments, the curable emulsion further comprises nonionic surfactant. Methods of making the curable emulsions and their use in the manufacture of abrasive articles are also disclosed.

Curable emulsions and abrasive articles therefrom

An abrasive article is provided having a rebulkable nonwoven web and a continuous sheet-like abrasive coating bonded to the first major surface of the nonwoven web. The abrasive coating comprising a plurality of abrasive particles dispersed in a binder.

Nonwoven abrasive articles and method of preparing same

Structured abrasive articles having an abrasive coating including a binder which comprises the reaction product of a binder precursor and a reactive siloxane polymer are described as well as methods of making same. The reactive siloxane polymers have at least one functional group which is capable of reacting with the binder precursor.
