Patent number: 6512039Abstract: What is disclosed is an adhesive composition that exhibits substantial durability in bonding peroxide cured elastomers to many substrates. The invention is directed to adhesives consisting essentially of a diluent, a maleimide compound, acid scavenger, a polymeric film former and precipitated silica, optionally a phenolic resole, polyyisocyanate, or isocyanatosilane. The present invention is further directed to a method of bonding peroxide-curable elastomers to metallic surfaces whereby the substrate ius coated with the adhesive composition, drying the adhesive composition coating, applying a peroxide-cured elastomer to the adhesive composition coating, and curing the assembly with heat and/or pressure.Type: GrantFiled: November 16, 2001Date of Patent: January 28, 2003Assignee: Lord CorporationInventor: Douglas H. Mowrey

Patent number: 6414073Abstract: A pressure-sensitive adhesive material comprises a pressure-sensitive adhesive layer comprising 100 parts by weight of natural rubber and 10 to 120 parts by weight of styrene-isoprene-styrene block copolymer (SIS) having a radiate configuration with a styrene content of 10 to 45% by weight. Preferably, the pressure-sensitive adhesive layer is free of metals or metal compounds. The pressure-sensitive adhesive layer may contain 5 to 150 parts by weight of a tackifier having an acid value of 1.5 or more. The pressure-sensitive adhesive material includes (A) a backing-less tape having a release liner having on one surface thereof the pressure-sensitive adhesive layer and (B) a double-coated tape having a backing having respective pressure-sensitive adhesive layers on surfaces thereof, at least one of which is constituted by the pressure-sensitive adhesive layer of the above-described type.Type: GrantFiled: March 27, 2000Date of Patent: July 2, 2002Assignee: Nitto Denko CorporationInventors: Koichi Nakamura, Hiroshi Yamamoto, Tatsumi Amano, Kazuhiko Shibata, Chiaki Harada

Patent number: 6228931Abstract: A low-solvent aqueous binder includes: a water-insoluble synthetic resin component A; and an emulsifier resin B in a mass ratio of A to B of from 70:30 to 30:70. The emulsifier resin B is a reaction product of a water-insoluble synthetic resin B1 that includes hydroxyl groups as functional groups, a synthetic resin B2 that includes carboxyl groups as functional groups, and a neutralizing agent for the carboxyl groups of B. The amount of the neutralizing agent is such that the neutralizing agent is able to neutralize from 5 to 200% of the carboxyl groups of B. A process for preparing a low-solvent aqueous binder includes: mixing the water-insoluble synthetic resin component B1 comprising hydroxyl functional groups and the synthetic resin B2 in bulk or dissolved in an organic solvent to form a mixture; removing the solvent by applying subatmospheric pressure and heating until the content of the mixture is at least 85% by mass; maintaining the mixture at a temperature from 90° to 150° C.Type: GrantFiled: March 9, 1999Date of Patent: May 8, 2001Assignee: Vianova Resins AGInventors: Werner Wilfinger, Ingo Kreissmann, Kurt Gossak, Johann Luttenberger
