Abstract: A method of reusing a hub in an abrasive assembly is presented that includes removably coupling the abrasive wheel to a reusable hub. The abrasive wheel has an outer circumference and an inner circumference. The abrasive article has an inner circumference and an outer circumference. The method also includes abrading a worksurface by contacting the abrasive wheel to the worksurface. The reusable hub includes a coupling feature configured to directly couple to the abrasive article. The coupling feature includes an adhesive-free connection between the reusable hub and the abrasive wheel. The direct connection is a removable interlocking between the abrasive wheel and the reusable hub.

Abstract: A curable composition includes a polyamide composition that includes a first polyamide. The first polyamide includes a tertiary amide in the backbone thereof and is amine terminated. The curable composition further includes an amino functional compound comprising from 2 to 20 carbon atoms, a multifunctional (meth)acrylate, an epoxy resin, and an inorganic filler. The inorganic filler is present an amount of at least 25 wt. %, based on the total weight of the curable composition.
