Abstract
Abrasive foam articles and a method of manufacture of such articles are described. The articles of the invention comprise a flexible and resilient foam substrate having first and second major substrate surfaces, at least one of the surfaces having a plurality of open cells substantially across the substrate surface, the open cells having coatable surfaces defined by interconnected voids; and a plurality of abrasive particles adhered to said coatable surfaces of said open cells in a substantially uniform manner.

A flexible abrasive article comprising:
- a flexible and resilient foam substrate having first and second major substrate surfaces, at least one of the surfaces having a plurality of open cells substantially across the substrate surface, the open cells having coatable surfaces defined by interconnected voids;
- and
- a plurality of abrasive particles adhered to said coatable surfaces of said open cells in a substantially uniform manner wherein said particles are adhered to said coatable surfaces using a cured hard, non-elastomeric adhesive.
