Abstract: The method of the present invention is directed to masking or protecting a substrate utilizing a protection sheet (10) having a contact surface containing a plurality of protrusions (14) spaced apart by a plurality valleys (12), and an opposing back surface containing a plurality of hollow portions corresponding to the protrusions (14). The valleys (12) of the contact surface of the protection sheet (10) are coated with a pressure sensitive adhesive (16), while the protrusions (14) provide spacing which prevents premature sticking of the protection sheet (10) onto the substrate. The invention is particularly suited for use in automotive repair applications.

Abstract: A method of protecting a substrate using a protection sheet is disclosed. The protection sheet comprises a multilayer structure having a support layer and a thermoplastic backing layer, wherein the support layer contains a plurality of raised portions and a plurality of anchor portions bonded to a surface of the backing layer. The raised portions of the protection sheet are capable of releasably engaging with a mechanical mating member. In an embodiment, the backing layer of the protection sheet is surface treated to increase wetting tension to facilitate the adherence of paint particles to the surface of the protection sheet. The protection sheet may be used to protect horizontal substrates, vertical substrates, and objects, such as the walls of a paint booth, a work surface and a vehicle.

Abstract: A flexible window is formed by a multi-layer sheet having a transparent flexible base layer and one or more transparent flexible protective layers, wherein the protective layers have a greater abrasion resistance than the base layer. The base layer and the protective layers are formed of substantially plasticizer-free polymeric materials.

Abstract: A simultaneously biaxially oriented polypropylene film is formed from a propylene containing polymer resin. The film has a machine direction and a transverse direction. The oriented film has a tensile strength in the machine direction of at least 190 N/mm2, and a normalized haze value of less than or equal to 8%/mm.
