Abstract
An abrasive disc includes a backing layer on a first major surface, a water-impermeable abrasive layer on a second major surface, and a water-absorbable, compressible, resilient, porous foam layer sandwiched in between the backing layer and the abrasive layer. The disc further includes a plurality of perforations. The disc is used to abrade a surface. Fluid is absorbed into the abrasive disc. The fluid is then released to the surface by compressing the abrasive disc against the surface in an abrading motion. The fluid is allowed to mix with and absorb surface swarf; and compression on the abrasive disc is released, reabsorbing the fluid and trapping swarf inside the disc.

An abrasive disc comprising a backing layer at a first major surface, an abrasive layer at a second major surface, and a water-absorbable, compressible, resilient, porous foam layer sandwiched in between the backing layer and the abrasive layer, the disc further including a plurality of perforations in the abrasive layer and in the foam layer,
- wherein the foam layer has a cell count between about 15 cells/cm and 50 cells/cm, and a density between about 30 kg/m3 and 80 kg/m3.
