Abstract: The invention provides a backing for an abrasive article comprising a sheet-like polymeric substrate having a first major surface including a pattern of non-abrasive raised areas and depressed areas and an opposite second major surface including a plurality of shaped engaging elements that are one part of a two-part mechanical engagement system. An abrasive product is provided by coating at least the raised areas of the backing with an abrasive coating.

Abstract: Coated abrasive articles comprise a backing and an abrasive layer, wherein at the abrasive layer comprises a reaction product of components comprising polyfunctional acrylate, alicyclic polyepoxide, and aromatic polyepoxide having an average epoxy functionality of at least 2.5.

Abstract: The invention provides a substantially flat coated abrasive article having a fabric-reinforced backing which may include engaging elements such as hooks for releasable attachment to the surface of an abrading apparatus and a method of making the article. The invention also provides an abrading apparatus which includes a back-up pad having releasably attached thereto the abrasive article. The article comprises a substantially flat sheet-like substrate comprised of thermoplastic material and a porous fibrous reinforcing element contained within the substrate and an abrasive layer disposed on a surface of the substrate. The opposite surface of the substrate may include the engaging elements. The article is made by deploying the fabric on a surface, depositing molten thermoplastic polymer over the fabric, removing the substrate from the surface and applying the abrasive layer to one surface of the substrate.

Abstract: A granular material which includes an inorganic substrate has a ceramic coating which substantially reduces dust generation during processing of the granular material. The ceramic coating comprises the reaction product of an alkali metal silicate and an aluminosilicate, the ceramic coating further including a magnesium complex and an alkali metal chloride. The magnesium complex and alkali metal chloride are dispersed within the coating. It has been found that the use of magnesium chloride alone eliminates the use of oil in preventing dusting of the resultant granule material. Methods of producing such ceramic-coated granular materials are also disclosed, as well as methods of reducing dust generation using magnesium chloride.
