Abstract
An abrasive article includes a backing having a major surface, an adhesion promoting layer overlying the major surface of the backing, and a make layer directly contacting the adhesion promoting layer. The adhesion promoting layer has a thickness of at least about 10 microns and is formed of a polar thermoplastic material, a cross-linkable polymer, or blends thereof.
Claims11
An abrasive article comprising:
- a backing having a major surface;
- an adhesion promoting layer, the adhesion promoting layer having a thickness of about 25 microns to about 50 microns and formed of a polar thermoplastic material;
- a primer layer including polyethylene imine disposed between the adhesion promoting layer and the backing;
- and
- a make layer directly contacting the adhesion promoting layer, and
- abrasive grains disposed on or within the make layer,
- wherein the backing includes a corona treated polymer film,
- wherein the polar thermoplastic material includes a blend of a copolymer of ethylene and methyl acrylate and a terpolymer of ethylene, acrylic ester, and maleic anhydride.
