Embodiment 1

[0121] Abrasive slurry AS-1 was applied to a microreplicated polypropylene mold MRT-1 by knife coating at a coat weight of about 5.5 mg / cm 2 . A slurry-filled polypropylene mold was brought into contact with a commercially acceptable TEGADERM on a polyurethane elastomer film commercially available from 3M Company in St. Paul, Minnesota and UV cured using a UV processor with two "D" bulbs from Fusion Systems in Gaithersburg, Maryland Company (FusionSystems Inc., Gaithersburg, Maryland). The mold is then removed to expose the microreplicated abrasive coating onto the carrier film.

[0122] A nonwoven web having protrusions with dimensions of about 4 mm width, 3 mm length and 85 μm height, such as Figure 5 Commercially available from N.R. Spuntech Industries Ltd., Hinckley, Leics., UK (N.R. Spuntech Industries Ltd., Hinckley, Leics., UK) with product number "2EO70V40P50M10," as seen in Apparently, the adhesive layer is commercially available from 3M Company, St. Paul, MN und...

Embodiment 2

[0124] Example 2 was prepared as described in Example 1, except that the nonwoven web from Example 1 was replaced with a nonwoven material having protrusions with dimensions of about 5 mm width, 5 mm length and 50 μm height (under the product code " 2SQ70V40P50M10" commercially available from N.R. Spuntech Industries, Hinckley, Leicestershire, UK).

Embodiment 3

[0126] Example 3 was prepared as described in Example 1, except that the nonwoven web from Example 1 was replaced with a nonwoven material having protrusions with dimensions of about 3 mm width, 3 mm length and 30 μm height (designated under the product code " 13 SD50V50P40Y10" commercially available from N.R. Spuntech Industries, Hinckley, Leicestershire, UK).

Abstract

The present invention provides a multilayer abrasive article comprising an abrasive composite having shaped features, a carrier film, and a nonwoven web, wherein the nonwoven web and the carrier film have discrete three-dimensional protrusions aligned with each other The corresponding pattern of the department. A compressible foam backing extends across the major surface of the nonwoven web facing away from the carrier film. Multilayer abrasive articles including abrasive composites, a carrier film, and a nonwoven web are also provided. The nonwoven web and the carrier film have a corresponding pattern of discrete three-dimensional protrusions aligned with each other, and the formed features and three-dimensional protrusions of the nonwoven web have an average diameter:average diameter in the range of 1:50 to 1:5 diameter ratio.

Description

technical field [0001] Abrasive articles and related methods are provided herein. The provided abrasive articles are useful in surface modifying applications, such as the polishing of painted automotive exteriors. Background technique [0002] There is a wide variety of industrial applications in which abrasive articles are required to produce a desired surface finish. Specific applications include, for example, the polishing of glossy surfaces found in automotive and marine clearcoat finishes and paint finishes. Other applications include cleaning or scraping operations on surfaces of metal, wood, plastic and composites. To produce the desired surface finish, service providers often use flexible abrasive pads that can be manipulated by hand or using motorized power tools. Such abrasive pads are capable of removing small defects and removing material from the surface of a workpiece (or substrate) in a controlled manner. [0003] Certain abrasive articles, generally refer...
