Publication number: 20090095400Abstract: 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: ApplicationFiled: October 10, 2008Publication date: April 16, 2009Inventors: John D.

Patent number: 7186458Abstract: An adhesive tape comprising a backing and a layer of adhesive on the backing. The backing comprises a biaxially oriented substrate which comprises an isotactic polypropylene composition. The tapes and backings of this invention can be severed readily using commercial tape dispensers having metal or plastic cutting teeth to produce cleanly serrated cut edges on the tape. The biaxially oriented substrate is preferably made from a resin comprising an isotactic polypropylene homopolymer having a melt flow rate greater than 8 grams/10 minutes, more preferably greater than 12 grams/10 minutes, and still more preferably greater than about 20 grams/10 minutes. One preferred way to obtain such a resin is to blend: A) at least one isotactic polypropylene homopolymer “A” having a weight average molecular weight of at least 350,000 grams/mole and melt a flow rate of about 0.5–8 grams/10 minutes, more preferably about 0.Type: GrantFiled: January 21, 2004Date of Patent: March 6, 2007Assignee: 3m Innovative Properties CompanyInventors: Scott D.

Patent number: 6638637Abstract: A multi-layered biaxially oriented film comprising at least one primary layer and at least one secondary layer, wherein the primary layer comprises a propylene copolymer having a first melting point and the secondary layer comprises a polypropylene homopolymer or copolymer having a second melting point, such that the second melting point is greater than the first melting point and the multi-layered construction is biaxially stretched. The multi-layered film further includes a surface finishing layer, to provide a writable multi-layered film. This stretched film exhibits a refractive index in the machine direction (MD) that is greater than the refractive index measured in the transverse direction (TD).Type: GrantFiled: January 22, 2001Date of Patent: October 28, 2003Assignee: 3M Innovative Properties CompanyInventors: Patrick J.

Publication number: 20030134112Abstract: A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e., less than about 35°, to the surface of the substrate.Type: ApplicationFiled: January 21, 2003Publication date: July 17, 2003Applicant: 3M Innovative Properties CompanyInventors: Karl W.
