Patent number: 8734205Abstract: A macro-porous abrasive article includes a spun lace substrate having a macro-porous structure and a coating. The coating is made of a resin binder and abrasive aggregates. The abrasive aggregates are formed from a composition of abrasive grit particles and a nanoparticle binder. The coating is at least partially embedded in the substrate. A method for making the macro-porous abrasive article includes combining abrasive aggregates of abrasive grit particles and a nanoparticle binder with a resin binder to form a slurry. The slurry is applied to a macro-porous support structure so that the slurry at least partially penetrates the substrate. The resin is then cured to bond the aggregate grains to the substrate.Type: GrantFiled: December 14, 2009Date of Patent: May 27, 2014Assignees: Saint-Gobain Abrasives, Inc., Saint-Gobain AbrasifsInventors: Paul S. Goldsmith, Anthony C. Gaeta, James J. Manning, Kamran Khatami

Patent number: 6355344Abstract: Flexible, conformable, pressure sensitive adhesive film material has a plastic film and a compatible pressure sensitive adhesive layer on at least a first surface of the plastic film. The plastic film is formulated of plastic film polymers and optional additives. The plastic film polymers include, at least, thermoplastic ethylene/styrene interpolymer in major part, and a temperature modifier polymer, which increases the thermal resistance of the plastic film. The pressure sensitive adhesive layer is compatible with the plastic film, such as acrylic-based adhesive and shear-coated rubber-based adhesive. The PSA film material can be harness tape for use in wire harness constructions and can provide advantageously low fogging and good recyclability, along with performance characteristics suitable to stringent harness tape and other end-use applications. In certain embodiments, a plastic barrier layer is coextruded with the plastic film, and a surface of the plastic film opposite the adhesive layer.Type: GrantFiled: May 21, 1999Date of Patent: March 12, 2002Assignee: Tyco Adhesives LPInventors: Abboud L. Mamish, Paul S. Goldsmith, Serra M. Jerry
