Abstract: An apparatus can comprise a body and a first portion. The first portion can be coupled to the body and moveable therewith. The first portion can comprise a rigidifying material and a layer. The rigidifying material can be positioned in a chamber defined by an envelope formed of a gas-impermeable material. A pressure within the chamber can be variable between at least a lower pressure state and a higher pressure state. In the higher pressure state the material is relatively flexible, and in the lower pressure state the material can be relatively less flexible than in the higher pressure state. The layer can be manipulatable by the rigidifying material. More particularly, the layer can have a first state when the pressure within the chamber is in the higher pressure state. In the first state, the layer can be formable by the target surface to take on a desired shape that can be substantially a match of the target surface. The layer can have a second state when the pressure within the chamber is in the lower pressure state. In the second state, the layer can maintain the desired shape and can be substantially less formable than in the first state.

Abstract: An abrasive article is provided which comprises a plurality of layers in the following order: a backing; an abrasive layer; a primer layer comprising clay particles, wherein the clay particles are agglomerated and form a layer; and a supersize coat comprising a metal salt of a long-chain fatty acid. The addition of the aforementioned primer layer can significantly reduce loading of swarf and improve both the cut and expected lifetime of the abrasive article.

Abstract: A flexible abrasive article is provided with a first, non-tacky base layer having opposed first and second major surfaces. An ink layer is disposed on the first major surface of the first base layer, while a second, thermoplastic base layer is disposed on the ink layer whereby the ink layer is located between the first and second base layers. Disposed on the second base layer is an abrasive layer such that the second base layer is located between the abrasive layer and the ink layer. Compared with conventional printed flexible adhesive articles, the provided articles improved robustness while avoiding manufacturing difficulties related to flexographic printing onto abrasive coated articles.

Abstract: The disclosure is directed to methods, systems, and apparatus for obtaining flame-perforated films which reduce or eliminate skewing of perforations in such films caused by thermal creep, whereby the film has perforations arranged to provide controlled tear characteristics, especially in both the lengthwise or machine direction (MD), and the crosswise or transverse direction (TD).

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: 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.

Abstract: Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a coating pattern characterized by a plurality of discrete islands. The coating pattern has features in which all three components are generally in registration with each other, while providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.

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.
