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.

Flexible abrasive article with image layer

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.

Abrasive sheet including a plurality of protrusions

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.

Abrasive articles, assemblies, and methods with gripping material

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.

Printed abrasive article

Provided herein are abrasive compositions that use surfactants containing block copolymers of both propylene oxide and ethylene oxide moieties. Abrasive compositions derived from these copolymers were capable of providing both superior levels of cut rate while preserving a high quality surface finish on gelcoat surfaces comparable to those achieved using conventional rubbing compounds.

Abrasive composition

This limb bundler and trash bag holder comprises a foldable frame 10 having two pairs of sub-frame members 12 and 14, preferably identical, each such member having a lower leg portion 20, 20a, 30 or 30a, and an upper leg portion 22, 22a, 32 or 32a, and intermediate portions 24, 24a, 34 or 34a. Each of the sub-frame members 12 and 14 is pivotally hinged to the other for joint movement and pivotal foldability. Swiveling wheels 36-39 are affixed at the bottom of each leg portion 20, 20a, 30 and 30a and cap-like end protectors 40-43 are provided upon the extremities of the respective legs. A pair of foldable brace members 48 and 48a are attached to the sub-frame members 12 and 14 for restraint against excessive frame member distortion and to accommodate folding. A secondary brace and trash bag support 56 is connected between the first-mentioned brace members 48 and 48a. A twine holder and dispenser 64 is mounted to the brace 56 and a twine cutter 98 is attached to one of the frame members. A trash bag holder 100 and a glove holder 104 are also sometimes provided for purposes of convenience.
