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: 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: Provided are abrasive articles that include a plurality of layers, in the following order: a backing; an abrasive layer; and a supersize coat. The supersize coat contains a metal salt of a long-chain fatty acid and clay particles dispersed therein. Advantageously, the clay particles enhance the optical clarity of the supersize coat, allowing printed abrasive articles to be made with thicker supersize coatings. The addition of clay was also found to improve cut performance of the abrasive article relative to articles in which the clay particles are absent.

Abstract: A method of providing an easy-clean, water-sheeting coating on a substrate includes: abrading a surface of a substrate using an abrasive article to provide an abraded surface having a surface roughness R?a#191 in a range of from 100 nm to 3500 nm, contacting a coatable composition with the abraded surface, and removing water from the coatable composition. The coatable composition comprises silica nanoparticles and has a pH of 7.5 or less. A kit including the abrasive article and the coatable composition is also disclosed.
