An abrasive article comprising an attachment layer and an abrasive layer. The attachment layer comprises a porous backing having a first major surface, an opposed second major surface, and a first plurality of voids extending from the first major surface to the second major surface. The abrasive layer has a third major surface and an opposed fourth major surface and comprises a cured composition, abrasive particles at least partially embedded in the cured composition, and a second plurality of voids extending from the third major surface to the fourth major surface. The first major surface of the attachment layer is adjacent the third major surface of the abrasive layer, and the pattern of the second plurality of voids is independent of the pattern of the first plurality of voids.

Porous abrasive article

The disclosure relates to an abrasive article comprising: a fabric substrate comprising strands forming first void spaces between the strands; a laminate joined to the fabric substrate; a cured resin composition joined to the laminate opposite the fabric substrate; abrasive particles joined to the cured resin composition; and a plurality of second void spaces extending through the laminate coinciding with first void spaces in the fabric substrate. The disclosure also relates to methods of making such abrasive articles.

Abrasive article

The disclosure relates to layers comprising a body having a thickness, T, comprising a curable composition comprising a polymerizable epoxy-acrylate resin composition and abrasive particles at least partially embedded in the polymerizable epoxy-acrylate resin composition, wherein the body includes a plurality of void spaces free of the curable composition extending into the body from the first major surface and the depth of the plurality of void spaces is at least 10 percent of thickness T. The disclosure also relates to cured compositions formed from such curable compositions and, in turn, abrasive articles made from such cured compositions as well as methods for making abrasive articles.

Described herein is an improved abrasive material () in which the cutting performance is orientation-independent. The abrasive material () comprises an abrasive structure () including a plurality of elongate abrasive elements () aligned to be define a first open square. A plurality of pyramidal abrasive elements () arranged in a second open square are located within the first open square defined by the elongate elements ().

Abrasive material with different sets of plurality of abrasive elements

An apparatus for remotely performing an operation on a roof including a frame assembly configured to be positioned on the roof, a pivot assembly configured to couple to an external anchor point such that the frame assembly is positioned between the pivot assembly and an operating position, and a flexible control line including a first segment having a first end coupled to the frame assembly and extending in substantially a first direction to a second end disposed at the operating position, and a second segment having a first end coupled to the frame assembly and extending in a second direction substantially opposite the first direction through the pivot assembly, which redirects the second segment to the first direction, to a second end at the operating position, wherein pulling the second ends of the first and second segments controls movement of the frame assembly on the roof.

Apparatus for remote operation on a rooftop

Provided are abrasive articles having a plurality of elongated channels extending across its working surface and intersecting with each other. These channels provide hinge points that enhance flexibility of the article along two or more directions. Optionally, the abrasive article includes a flexible attachment layer, along with apertures that penetrate through the attachment layer located at the intersection points of the channels. The enhanced flexibility allows the abrasive article to easily access recessed areas of the workpiece and facilitates applying even pressure across convex and concave surfaces. The channels assist in segregating dust particles from the abrading operation, and the optional apertures can be advantageously connected to a vacuum source for evacuation of the dust particles from the channels.

Flexible abrasive article and methods of making

Methods of abrading surfaces by rotationally reciprocating abrasive surfaces in contact with the surfaces, abrasive articles for use in rotationally reciprocating tools, and methods of removing defects in a surface, where the methods include sanding using a rotationally reciprocating abrasive surface followed by one or more polishing operations are disclosed.

A system is provided wherein a plug flow reactor is used to make combinatorial libraries of materials. Examples of plug flow reactors include stirred tube reactors, extruders, and static mixers.

Continuous process for the production of combinatorial libraries of materials

The invention is a display article having a flexible substrate which includes a writing surface capable of being used as a dry erase surface. A peripheral edge extends around the writing surface. A flexible framing strip is affixed to the writing surface at a position proximate to the peripheral edge. One embodiment of the display article can be made by forming a substrate having a writing surface. The substrate defines a periphery edge, a back surface, and a plurality of mushroom shaped hooks extending from the back surface substantially over the entire back surface. The writing surface is capable of being used as a dry erase surface. At least a portion of the periphery of the writing substrate is folded over to form a framing strip having a plurality of exposed mushroom shaped hooks. The framing strip is secured to the writing surface.

Dry erase article

The invention provides a method of making an embossed abrasive article comprising providing a sheet-like foam backing having a first surface and an opposite second surface; providing an abrasive coating comprising abrasive particles and binder over said first surface to provide an abrasive article; and applying under pressure a patterned embossing tool having an embossing surface including at least a pattern of raised areas to the abrasive coating of the abrasive article to provide an embossed pattern at least including depressed areas corresponding to the raised areas of the embossing surface in said abrasive coating and said foam backing to provide an embossed abrasive article.

Method of making an abrasive product

The present invention provides a flexible abrasive product comprised of an open cell foam backing, a foraminous barrier coating and a shaped foraminous abrasive coating. The flexible abrasive article of the invention is made by applying a curable barrier coating over an open cell foam backing, curing the curable barrier coating to provide a foraminous barrier coating having openings therethrough corresponding to openings in the open cell foam, applying a coating composition comprising a curable binder and abrasive particles over the foraminous barrier coating, imparting a textured surface to the coating composition with a production tool which has a textured surface which is the inverse of the textured surface of the abrasive coating and to which production tool textured surface any coating composition coated over an opening of the first major surface may adhere, at least partially curing the binder, and separating the production tool from the textured surface to provide the shaped foraminous abrasive coating.
