摘要： A method for making agglomerate particles from a composition comprising at least a radiation curable binder and solid particulates. The method comprises the steps of forcing the composition through a perforated substrate to form agglomerate precursor particles which then separate from the perforated substrate. Then, the particles are irradiated to form soldified, handleable agglomerate particles before being collected.

摘要： The present invention involves the use of powder coating methods to form coated abrasives. In one embodiment, the powder is in the form of a multiplicity of binder precursor particles comprising a radiation curable component. In other embodiments, the powder comprises at least one metal salt of a fatty acid and optionally an organic component that may be a thermoplastic macromolecule, a radiation curable component, and/or a thermally curable macromolecule. In either embodiment, the powder exists as a solid under the desired dry coating conditions, but is easily melted at relatively low temperatures and then solidified also at reasonably low processing temperatures. The principles of the present invention can be applied to form make coats, size coats, and/or supersize coats, as desired.

摘要： A coated abrasive backing consisting of an endless, seamless, loop is provided. The backing loop includes about 40-99% by weight of an organic polymeric binder, based upon the weight of the backing; and an effective amount of a fibrous reinforcing material engulfed within the organic polymeric binder material. The endless, seamless backing loop includes a length with parallel side edges, and at least one layer of fibrous reinforcing material engulfed within the organic polymeric binder material such that there are regions of organic binder material free of fibrous reinforcing material on opposite surfaces of the layer of fibrous reinforcing material. The fibrous reinforcing material can be in the form of individual fibrous strands, a fibrous mat structure, or a combination of the these. A method for preparing the endless, seamless backing loop for a coated abrasive belt is also provided. The method includes the steps of preparing a loop of liquid binder material having fibrous reinforcing material therein around the periphery of a drum; and solidifying the binder material such that an endless, seamless, backing loop having fibrous reinforcing material engulfed within the organic polymeric binder material is formed.

摘要： A seamless, composite belt that is designed to maintain a substantially flat surface in the span between two rollers. The belts typically have one or more polymer layers, including the polishing layer, and one or more supporting woven or non-woven layers. The belts have the necessary balance between down-cupping and up-cupping forces achieved by: 1) varying the relative thickness of the different polymer and supporting layers in the belt, 2) varying the relative hardness or rigidity of the different layers in the belt, 3) varying the temperatures at which the different layers are formed, 4) varying the compositions of supporting layers, and 5) prestressing one or more of the composite layers. The belts are particularly useful in chemical mechanical polishing of semiconductor wafers.

摘要： In a chemical mechanical polishing (CMP) device, a semiconductor wafer is held by a carrier with its surface to be polished facing upward. A polishing belt is fed from one reel and taken up by the other reel by way of pulleys, running in contact with the surface of the wafer to be polished. A conditioning pad conditions the front or polishing surface of the belt facing the wafer. A nozzle feeds polishing slurry to the rear of the belt not facing the wafer. A plurality of press rollers cause the slurry to exude from the front of the belt while pressing the slurry and belt against the surface of the wafer. The belt filters out impurities introduced into the slurry.
