Abstract: An abrasive article having a removable support sheet having a first major surface. An image layer containing inks applied over the first major surface. A polyurethane backing layer having a first major backing surface located adjacent to the image layer and a second major backing surface opposite the first major surface. A functional layer comprising an abrasive layer applied to the second major surface; the abrasive layer comprising a make coat, abrasive particles and a size coat.

Abstract: A method for imparting hand-tearability to an organic polymeric film by impinging a multiplicity of ceramic microblades on a major surface of the organic polymeric film. The resulting microfractured organic polymeric film can be used as a hand-tearable tape backing for a hand-tearable adhesive tape.

Abstract: Various embodiments disclosed relate to an abrasive sheet. The abrasive sheet includes a first layer including an abrasive major surface and an opposite second layer defining a second major surface. The second major surface includes a plurality of protrusions extending outwardly from the second major surface. The protrusions include a first polymer component having at least one of a Shore A hardness ranging from about 5 to about 100 and a Shore D hardness ranging from about 1 to about 70. The first layer and the second layer are directly joined to each other.

Abstract: An abrasive article is provided that has a backing having opposed first and second major surfaces, an abrasive layer disposed on the first major surface, and a plurality of protrusions extending outwardly from the second major surface. The protrusions comprise a polymer having a Shore A hardness ranging from 5 to 90. These articles provide an alternative sanding solution enabling abrasive articles lacking an attachment layer to be handled effectively and efficiently, providing for a technically superior abrasive sheet on the marketplace that does not use or require an attachment layer.

Abstract: Various embodiments disclosed relate to an article. The article includes a first layer defining a first major surface of the article. The first layer includes a plurality of protrusions extending outwardly from the first major surface. The protrusions comprise an elastic polymer component. The article further includes a second layer opposite the first layer, which at least partially defines a second major surface of the article. The first layer is disposed over a range of about 5% surface area of the second layer to about 99% surface area of the second layer. The first layer and the second layer are in direct contact.

Abstract: A sheet of coarse sandpaper includes a backing layer having opposed first and second major surfaces, an adhesive make coat on the second major surface, coarse abrasive particles at least partially embedded in the make coat, thereby defining a coarse abrasive surface, and an exposed non-slip coating layer on the first major surface. Methods of making and using such coarse sandpaper are also provided.

Abstract: A flexible abrasive article includes a unitary backing having first and second opposed major surfaces and comprising a polyurethane. In some embodiments, the backing has an average thickness of from 4 to 6 mils (102 to 152 microns), a tensile strength of 500 to 3200 psi (3.45 to 22.1 MPa), and an ultimate elongation of 230 to 530 percent. In some embodiments, the flexible abrasive article has a tensile strength of 400 to 2400 psi (2.8 to 16.5 MPa), and a ultimate elongation of 180 to 380 percent. An abrasive layer is disposed on and secured to the unitary backing.

Abstract: The present invention provides an abrasive article, e.g. a sheet of sandpaper, comprising a backing layer having opposed first and second major surfaces, an adhesive make coat on the second major surface, abrasive particles at least partially embedded in the make coat, thereby defining an abrasive surface, and an exposed non-slip coating layer on the first major surface, the non-slip coating layer comprising at least a base resin and a tackifying resin.
