An anti-wear composite structure includes an anti-wear layer that has a wear surface opposite an adhesive receiving surface and a thermosetting resin applied to the adhesive receiving surface. The thermosetting resin includes a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion. The thermosetting resin has an onset to cure in the ambient temperature band and has a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to a substrate.

A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.

Items that adhere to the skin for medical or paramedical use and methods of making and using the same are described.

The present utility model provides an easy-to-clean protective film, which belongs to the technical field of protective films for vehicles and other vehicles, and can solve the problems that lasting scratches are easily caused to the existing vehicle coatings and surface stains are not easy to clean. The easy-to-clean protective film provided by the present utility model comprises a polyvinyl chloride (PVC) bottom film and an easy-to-clean layer consisting of silicon dioxide particles, wherein the water contact angle of the easy-to-clean layer is small and thus the adhesive force of dust and oil stains can be reduced. After the surface of the easy-to-clean layer is contaminated by dust and oil stains, the dust and oil stains can be easily cleaned with a simple cleaning. The easy-to-clean protective film provided by the present utility model is suitable for use as protective coatings of various substrates, especially for attachment to the body surfaces of vehicles such as automobiles.

An applicator is provided for applying protective films to electronic device displays. The applicator includes a base, a screen protector, and a squeegee. The base includes a pocket for receiving an electronic device. The screen protector is affixed to the base so as to overlie an electronic device. The screen protector preferably includes three layers including a protective film, cap sheet, and back liner. The squeegee is provided for removing the back liner and for simultaneously affixing the protective film to an electronic device.

A system for applying a protective layer to a substrate, such as an electronic device, includes the protective layer, a dust removal layer on a contact surface of the protective layer, and a release film, or release liner, on a dust removal surface of the dust removal layer. The system may also include an application liner on an outer surface of the protective layer, opposite from the dust removal layer. A dust removal adhesive on the dust removal surface may clean a surface of the substrate to which the protective layer is to be secured. The dust removal layer may include two or more separate or separable sections, as well as pair of adjacent tabs on opposite sides of a boundary between adjacent sections of the dust removal layer. The adjacent tabs may facilitate removal of the adjacent sections of the dust removal layer from the contact surface of the protective layer to facilitate adhesion of the protective layer to the surface of the substrate. Methods for cleaning the surface of an electronic device in connection with securing a protective layer to the surface are also disclosed.
