    Abstract: A porous coated abrasive article comprises a porous backing having opposed first and second major surfaces, and a porous abrasive layer disposed on the first major surface. The porous backing comprises a porous oriented thermoplastic film. The porous backing has a land portion and openings extending between the first and second major surfaces. Each opening has a respective area at the first surface, wherein the openings have a number density of 5 to 4600 openings per square inch, and wherein the total area of the openings is from 1 to 90 area percent, based on the combined total areas of the land portion and the openings. The porous abrasive layer is disposed on the first major surface of the porous backing. The porous abrasive layer comprises abrasive particles retained in a binder and has an abrading surface opposite the porous backing, and the second major surface of the porous backing and the abrading surface are in fluid communication through at least some of the openings. A method of making the porous coated abrasive article using flame perforation is also disclosed.

    Abstract: The abrasive combinations of the present application include an abrasive article having a first abrasive surface and an opposite second surface, the second surface including a first plurality of uncapped projections; and a back-up pad comprising a first pad surface and a second pad surface, the first pad surface including a second plurality of uncapped projection, and wherein the back-up pad comprises suction apertures. In some embodiments, at least some of the first or second projections are selected from the group consisting of railings or stems. In some embodiments, the first and second uncapped projections are complementary. In some embodiments, when engaged, the first and second plurality of uncapped projections have a peel force equal to or less than 50 gf. In some embodiments, at least some of the first or second uncapped projections have a Shore A hardness of less than 90.

    Abstract: Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a pre-determined coating pattern. All three components are generally in registration with each other, thereby 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 translation: 提供了根据预定的涂层图案将制造层,磨料颗粒层和尺寸层涂覆到背衬上的研磨制品。 所有三个部件通常彼此对准,从而提供贯穿背衬的普遍的未涂覆区域。 有利地,与先前公开的磨料制品相比,这种构造提供了显示出优异的抗卷曲性的涂层磨料。 此外,该构造抵抗负载,抗剥离,具有增强的柔性,并且减少了达到与常规磨料制品相同性能水平所需的原材料的量。
