A coated abrasive article comprises a backing, a first binder on the backing, and a plurality of abrasive particles in the first binder. The first binder is a hot melt pressure sensitive adhesive that is energy cured to provide a crosslinked coating. The invention also relates to a method of producing such articles.

Abrasive articles and a method of making the abrasive articles are provided wherein the method laminates a make coat precursor to atypical backing materials that include materials generally deemed inappropriate by those skilled in the art such as open-weave cloth, knitted fabrics, porous cloth, loop materials, untreated paper, unsealed fabrics, opened or closed cell foams, nonwovens, spun-fibers and the like.

A process and apparatus for the plasma deposition of a carbon-rich coating onto a substrate is provided. This method includes the steps of: providing a substrate in a vacuum chamber; and generating a carbon-rich plasma in the vacuum chamber by injecting a plasma gas into a hollow cathode slot system containing a cathode made of two electrode plates arranged parallel to each other, providing a sufficient voltage to create and maintain a carbon-rich plasma in the hollow cathode slot system, and maintaining a vacuum in the vacuum chamber sufficient for maintaining the plasma. The plasma is deposited on the substrate to form a carbon-rich coating.

An apparatus for conducting surface characterizations of sample materials comprises an enclosure defining first and second substantially isolated operating chambers or regions. The operating regions are separated by narrow channels, and are preferably differentially pumped. An elongate substrate extends between the first and second regions. During operation, a sample surface to be studied is prepared on the substrate in the first region, is transported into the second region, and is analyzed thereat. In a preferred embodiment a continuous loop and pulley arrangement is provided, for the substrate. Also, for a preferred embodiment the first region is divided into first and second isolated chambers, through which the substrate is extended. A method is provided, whereby a surface can be prepared and analyzed. According to the method, the sample is applied to a substrate in a first region, and the substrate is transported into a second isolated region, through an elongate narrow channel. Differential pumping facilitates isolation of environments in the various regions.
