  • Patent number: 7125601
    Abstract: An integrated granule product that includes a film having a plurality of ceramic coated granules bonded to the film by a cured adhesive. The integrated granule product is generally considered an intermediate product because it is suitable for application onto various substrates for end use applications such as roofing products and flooring products.

  • Patent number: 5575873
    Abstract: Endless coated abrasive articles having a splice. In general, the coated abrasive articles comprise a backing having abrasive grains bonded thereto by one or more layers of binder. This invention also provides a method of making the splice by using radiation curable adhesives, e.g., acrylated urethanes, and radiation energy to cure the adhesives. The radiation curable splice adhesive essentially solvent-free. Consequently, the time required for the solvent to flash off is eliminated and solvent removal is no longer an environmental concern. By utilizing a source of radiation energy, the splice adhesive can be solidified in less than one minute. Because the splice adhesive is fully solidified, coated abrasive belts can be packaged immediately after the splice is formed.

  • Patent number: 5460802
    Abstract: The present invention is generally related to an oral disinfectant for companion animals. A preferred disinfectant is a concentrated composition containing a fatty acid monoester, one or more fatty acids, an acid or chelating agent, a polyalcohol, a surfactant and water. When used the concentrate is diluted with water and then applied to the teeth and oral cavity tissues of the animal.

  • Patent number: 5316849
    Abstract: A reclosable mechanical fastener comprising a fastening component having a surface structure by which two such fastening components can become releasably attached. The novel fastening component is a composite of a tough substrate and a fastening layer that forms said surface structure, which fastening layer is formed from a cured oligomeric resin composition having one or more like or different hard segments, one or more like or different soft segments, and one or more like or different monovalent moieties containing a radiation-sensitive, addition-polymerizable, function group. The novel fastener forms stronger linkages than were possible with similar fasteners of the prior art.

  • Patent number: 4927431
    Abstract: An abrasive product comprising abrasive grains bonded to at least one major surface of a backing sheet by a binder formed from a blend comprising radiation curable monomer and a thermally curable resinous material. The radiation curable monomer can be selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group, isocyanate derivatives having at least one terminal or pendant acrylate group, and multifunctional acrylate monomers. The thermally curable resinous material is preferably a member selected from the group consisting of phenolic resins, urea-formaldehyde resins, melamine-formaldehyde resins, and epoxy resins. The binder can be used to form the make coat, size coat, both make and size coats, or as a backing treatment for a coated abrasive product. The binder can also be used in fibrous nonwoven abrasive products. The binder can also be used in embodiments where only a single-coat binder is employed.

  • Patent number: 4652274
    Abstract: A coated abrasive product comprising abrasive granules adherently bonded to at least one major surface of a backing sheet by a radiation curable resinous binder material. The binder material can be used to form the make coat, size coat, or both coats. Alternatively, the binder material can be used in embodiments where only a single binder coat is employed. The radiation curable resinous binder material comprises a copolymer formed from a mixture comprising (1) at least one monomer selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group and isocyanate derivatives having at least one terminal or pendant acrylate group, and (2) at least one aliphatic or cycloaliphatic monomer having at least one terminal or pendant acrylate group.
