The abnormal noise preventing sheet 10 of this invention has a substrate 12 comprising a nonwoven fabric 122 and a PSA adhesive layer 14 provided on a first side 12A of the substrate. The PSA constituting the PSA layer 14 contains an acrylic polymer and a tackifier. This sheet 10 has a toluene emission level of 20 ?g or less per gram of PSA layer when the PSA layer 14 is heated at 80° C. for 30 min.Type: ApplicationFiled: June 8, 2010Publication date: March 29, 2012Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, NITTO DENKO CORPORATIONInventors: Kazuyuki Yagura, Mitsuo Matsumoto, Shuji Nakagawa

Patent number: 8143524Abstract: The invention relates to an industrial adhesive tape. The tape includes a tape-shaped textile dyed backing and an adhesive coating, in particular a pressure sensitive adhesive coating applied to at least one side of the textile dyed backing. To achieve significantly reduced inherent discoloration or decolorization and also reduced discoloration of the wrapped materials, and hence improved compatibility of the adhesive tape with the materials to be adhered together, such as cablesets, the textile backing is fabricated from spun-dyed threads or fibers.Type: GrantFiled: June 13, 2005Date of Patent: March 27, 2012Assignee: Coroplast Fritz Muller GmbH & Co. KGInventors: Gülay Wittig, Christoph Lodde

Patent number: 8105450Abstract: A protection sheet and method of protecting a substrate is disclosed. In an embodiment, the protection sheet comprises an adhesive coated nonwoven material. In an embodiment a surface of the protection sheet captures and retains paint overspray, dust, dirt and other contaminants so as to provide a cleaner paint job. In an embodiment the protection sheet may be laminated to a second nonwoven or woven material to allow clean removal after extended use. The protection sheet may be used to protect horizontal or vertical substrates, and is particularly suited to protect the surfaces of a paint booth used in automotive spray-painting operations.Type: GrantFiled: October 10, 2008Date of Patent: January 31, 2012Assignee: 3M Innovative Properties CompanyInventors: John D. Stelter, Troy K. Ista, Thomas J. Reid, Patrick J. Hager, Kevin M. Eliason

Patent number: 8071490Abstract: An acrylic pressure-sensitive adhesive composition according to the present invention comprises: acrylic copolymer (A) formed by copolymerizing i) alkyl(meth)acrylic acid ester monomer wherein the carbon atom of alkyl group is 2 to 14, ii) monomer having a functional group capable of crosslinking, iii) methyl(meth)acrylate monomer, iv) vinyl acetate monomer, v) glycidyl(meth)acrylate, and vi) crosslinking agent having 5 to 15 of alkyleneoxide groups and at least two acrylate group or vinyl group; and flame retardant (B). The acrylic pressure-sensitive adhesive composition improves the adhesive property and the dispersion of the flame retardant by controlling the crosslinking structure of the acrylic copolymer, such that a surface finishing material comprising the same can have the excellent adhesion and fireproof.Type: GrantFiled: August 20, 2009Date of Patent: December 6, 2011Assignee: LG Chem, Ltd.Inventors: Chang-bum Ko, Young-min Kim, Kong-ju Song, Kum-hyoung Lee
