Abstract:
A multi-layer screen protector for digital display screens, such as LCD's, cell phones, tablets, laptops, and pad computer devices, that may be readily applied without the need for special tools and in dusty environments, the screen protector being designed and die-cut to match the shape of the digital display screen, including cut-outs for cameras, microphones and device buttons, where the top surface is a layer of polycaprolactone aliphatic urethane that is connected to a bottom layer made from plastic such as polystyrene, acrylic and/or polyethylene terephthalate, and a self-wetting adhesive layer provided on the bottom surface of the bottom polystyrene, acrylic and/or polyethylene terephthalate layer. The screen protector provides an optically clear view of the device and is constructed with the abrasion resistant layer being provided and supported on a plastic layer and may be removed and reinstalled.
Abstract:
Disclosed is a pressure-sensitive adhesive sheet that has a transparent film substrate and, on at least one side thereof, an acrylic pressure-sensitive adhesive layer. The transparent film substrate has a top coat layer having a specific configuration with an average thickness and a thickness variation being controlled. The acrylic pressure-sensitive adhesive layer is formed from a water-dispersible acrylic pressure-sensitive adhesive composition. The composition includes, as components, an acrylic emulsion polymer derived from constitutive monomers in a specific formulation; a polyether compound having a specific structure; and a specific acetylenic diol. The pressure-sensitive adhesive sheet is found to be highly resistant to scratches and static electrification, to have superior visual quality and satisfactory resistance to adhesive strength increase, and to less cause stains.
Abstract:
A system for protecting a surface of a substrate includes a protective film, which is configured to be applied and secured to the surface, as well as a backing on an adherent surface of the protective film and an application tape over an exterior surface of the protective film. Protruding features, such as tabs, adjacent to different peripheral edges of the protective film may enable removal of the backing and the application tape from the protective film, and may include features that indicate the order in which each protruding feature is to be grasped to peel its corresponding element away from the protective film.
Abstract:
A pressure-sensitive adhesive sheet includes a base material and a pressure-sensitive adhesive layer and is formed therein with a plurality of through-holes passing through from one surface to the other surface. The base material includes a first layer positioned on a side of the pressure-sensitive adhesive layer and a second layer positioned on an opposite side of the pressure-sensitive adhesive layer. The first layer includes a resin composition containing 50 to 88 wt % of a polyolefin-based resin (A); 10 to 48 wt % of a styrene-based resin and/or an acrylic-based resin (B) excluding the polyolefin-based resin (A); and 2.0 to 30 wt % of a pigment (C), and the second layer contains a polyolefin-based ionomer resin (D) as a main constituent, and the ratio of thickness between the first layer and the second layer is 80:20 to 97:3.0.
Abstract:
A roof/wall structure includes a substantially rigid substrate and a waterproof membrane adhesively joined to an outer surface of the substrate. The membrane includes a layer of thermoplastic or elastomeric waterproof material, a layer of cushion material bound to an inner surface of the layer of waterproof material, and a pressure sensitive adhesive bound to a side of the layer of cushion material remote from the layer of waterproof material and bound to the substrate.
Abstract:
When a film that is fixed to a surface of an adherend by means such as adhesion and rolled into a cylinder by heating is grasped by a grasping tool or adhered to a holder in order to remove the film from the surface of the adherend, the grasping tool or holder applies a force to the rolled film to urge the film toward the surface of the adherend. If the rolled film is pressed flat by the force, the area of contact between the film and the adherend increases and so does the strength of adhesion between them. Consequently, the film needs to be re-grasped or reattached to the holder or a larger force is required in order to peel the rolled film off the adherend. To solve the problem, there is provided a film that includes a thermally shrinkable base material, an adhesive resin layer and a non-thermally shrinkable base material stacked in sequence and has the property of rolling up into a cylindrical roll by heating and not automatically returning to the original shape after the change into the cylindrical roll.
Abstract:
The present invention pertains to bonding an edge banding to the edge of wood or wood composite furniture by using a co-extruded dual compound polypropylene edge band that contains a main body of polypropylene and an EVA backing layer. The edge of the wood or wood composite material is bonded to a polypropylene edge band by an EVA backer layer that includes EVA-based glue. Bonding between the edge band and composite wood material is achieved without the use of a primer.
Abstract:
The invention relates to a peelable adhesive strip which is coated with a pressure-sensitive adhesive at least one side. Said adhesive strip is constituted of the following layers: a core layer having an elongation at tear of at least 300%, an external carrier layer having an elongation at tear of not more than 120% and at least some sections of which are connected to the core layer in such a manner that it becomes detached from the core layer when the same is stretched, a first adhesive layer at least some sections of which are applied to the side of the external carrier layer and which is opposite the side connected to the core layer.
Abstract:
A multi-layer surface covering includes at least a first and a second layer made of a polyvinyl chloride material, each of the two layers having a different density. One of the two layers includes a pigment such that the layer resembles teak. A surface of the colored layer is at least partly abraded to resemble a wood grain. The surface covering may additionally include grooves cut into the surface to resemble individual wood planks. The grooves additionally provide traction and drainage of liquid from the surface to an edge of the covering.
Abstract:
To provide a pressure-sensitive adhesive sheet used during processing articles such as semiconductor wafers and laminate sheet used for such a pressure-sensitive adhesive sheet, which does not contaminate or break the semiconductor wafers during the processing and can minimize the curl of the articles due to residual stress of the pressure-sensitive adhesive sheet, a multi-layer sheet includes a composite film containing a urethane polymer and a vinyl-based polymer as effective components and a first film made of a material different from that of the composite film, wherein the urethane polymer is formed from a polyolefin diol and a polyisocyanate. A pressure-sensitive adhesive sheet is obtained by providing a pressure-sensitive adhesive layer on at least one side of the multi-layer sheet.
