A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

A web of labels includes a face stock and a release liner. A top side adhesive layer extends on a top surface of the face stock and a top side release liner extends over the top side adhesive layer. The top side release liner includes at least one aperture exposing a corresponding portion of the top side adhesive layer. The face stock has a second adhesive layer on a bottom surface of the face stock. The release liner has a second release layer on a top surface thereof to protect the second adhesive layer, and a third release layer on a bottom surface of the release liner. The face stock is separated into a succession of labels carried on the release liner such that each label includes a portion of the top side release liner having at least one aperture.

A system includes a vacuum chuck; and a tape. The tape includes a flexible polymer substrate; and an adhesive die catching film disposed on the flexible polymer substrate facing a front surface of the flexible polymer substrate. The tape is held on the vacuum chuck by suction applied to a rear surface of the flexible polymer substrate.

An adhesive sheet including a first release film, a second release film disposed on the first release film, and an adhesive layer disposed between the first release film and the second release film, the adhesive layer including an upper surface facing the second release film, a lower surface facing the first release film, and a side surface extending from an edge of the lower surface to an edge of the upper surface. The side surface of the adhesive layer may be inclined with respect to a direction perpendicular to the upper surface and the lower surface.

Floor coverings having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component having adjoined first and second portions, and a plurality of fibers. The secondary backing material has an attached portion and a first exposable portion, with the attached portion adhered to the first portion of the primary backing component by contact with the adhesive layer. The second portion of the primary backing component is unattached to the first exposable portion of the secondary backing material, and the first exposable portion defines a portion of the first end edge of the floor covering. The second portion of the primary backing component is selectively moveable relative to the first portion to a position in which at least a portion of the second portion of the primary backing component does not overlie the first exposable portion of the secondary backing material.

Provided is a repair sheet for a mosquito window screen, including: a grid sheet (100); an adhesive layer (120) provided on the grid sheet (100); and a release liner (140) provided on the adhesive layer (120), wherein through-holes (110) are formed through the grid sheet (100) and the adhesive layer (120), wherein the release liner (140) is provided over the adhesive layer (120) and serves for a user to cut the repair sheet in a desired size and shape.

A dual lap high strength adhesive for sheet membrane application, having reflectivity granular particle layer to fully bond to concrete/shotcrete, and a method of making, and using same. More particularly, the invention encompasses a below grade, blind side, waterproofing sheet membrane with an inventive high strength adhesive, and having at least one layer of reflectivity granular particle layer that are partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is below 55 percent reflectivity on a standard reflectivity scale. The innovative reflectivity granular particle layer system that is securely bonded to concrete or shotcrete can be used along a wall, a floor, a ceiling, or along any structure which requires water or moisture proofing. The inventive high strength adhesive is along at least one edge of the sheet membrane, and could also be used to embed the reflectivity granular particle.

An adhesive-backed film with an adhesive layer having thermoplastic or thermoset filaments partially projecting therefrom, to promote fluid egress and repositionability.

Provided is a pressure-sensitive adhesive sheet capable of allowing a small electronic part (e.g., a chip having a size of 50 μm/□ or less) to be temporarily fixed in a satisfactory manner and satisfactorily peeled. The pressure-sensitive adhesive sheet of the present invention includes a gas-generating layer configured to generate a gas by being irradiated with laser light, wherein a modulus of elasticity Er(gas) [unit: MPa] of the gas-generating layer measured by a nanoindentation method and a thickness h(gas) [unit: μm] thereof satisfy the following expression (1):

Log(Er(gas)×10.sup.6)≥8.01×h(gas).sup.−0.116  (1).

In one embodiment, the pressure-sensitive adhesive sheet has a transmittance of from 0% to 35% for light having a wavelength of 360 nm. In one embodiment, the pressure-sensitive adhesive sheet has a transmittance of from 10% to 100% for light having a wavelength of 380 nm.

The invention relates to a film comprising an optionally multilayer carrier layer; wherein one surface side of the carrier layer has been modified over part of its area either by surface activation or by printing with a print medium, such that the surface side has modified regions and unmodified regions; wherein the modified regions and the unmodified regions are coated over part or all of the area by a release material; and wherein the strength of adhesion of the release material to the carrier layer in the modified regions is different compared to the adhesion of the release material to the carrier layer in the unmodified regions.
