Abstract:
The present invention provides a resin porous membrane with an adhesive layer that exhibits excellent bonding precision and can be bonded to an adherend while maintaining the gas permeability of the porous membrane even when the porous membrane is small, and a method for producing the resin porous membrane with the adhesive layer. The present invention also provides the filter member including the resin porous membrane with the adhesive layer.
Abstract:
Linerless labels are presented. A label includes a specific pattern or set of patterns of adhesive applied to one side of the label. The adhesive pattern(s) reduces contact between a cutter blade of a printer and the adhesive on the one side of the label. Moreover, the adhesive patterns reduce buildup of adhesive on the cutter blade and reduce buildup at specific locations on the cutter blade. That is, the adhesive patterns more evenly distribute adhesive buildup across the cutter blade. Consequently, the cutter blade can be used for a longer period of time before the cutter blade needs to be cleaned of the adhesive.
Abstract:
A multilayer protective tape for rotor blades of wind energy turbines said tape having a protective top layer comprising a polymer film and an adhesive bottom layer, wherein the top layer has a continuous surface (S) that is outwardly curved or outwardly trapezoidal surface such that the tape has a cross-sectional profile having an inner section between two lateral sections and wherein the inner section has a thickness (Ti) made up by the thickness of the top layer and adhesive bottom layer that is greater than the thickness of at least one of the lateral sections (T1,T2) made up by the thickness of the top layer and adhesive bottom layer and wherein the thickness (T1 or T2) of at least one lateral section is at most 600 μm and the thickness of the inner section (Ti) is at least 330 μm. Also provided are processes for making profiled tapes and methods for applying the tapes to rotor blades and blades containing protective tapes.
Abstract:
A fortified flashing laminate includes an uncured thermosetting polymeric layer having a top surface and a bottom surface. A first layer of vulcanized adhesive tape covers at least a portion of the bottom surface of the polymeric layer, and a second layer of vulcanized adhesive tape covers a portion of the first layer of vulcanized adhesive tape to form a fortified area. The size and positioning of the second layer of vulcanized adhesive tape may be selected to fortify known vulnerable areas of flashing laminates.

Abstract:
A method for producing a patterned pressure-sensitive adhesive body includes a pattern forming step of cutting a pressure-sensitive adhesive layer in a pressure-sensitive adhesive film including a first release film and the pressure-sensitive adhesive layer laminated on one surface of the first release film so as to form a first slit in a pattern shape and an outer frame forming step of cutting the first release film and the pressure-sensitive adhesive layer so as to form a second slit in an outer frame shape surrounding the pattern shape. The second slit has a discontinuous portion in a cutting direction.
Abstract:
The invention relates to a process for producing nanostructured and/or microstructured surfaces in an adhesive layer, more particularly in a self-adhesive layer, in which an adhesive polymer mixture, more particularly a self-adhesive polymer mixture, is guided into a nip formed by a relief roll, whose surface has been provided with a relief which represents the negative of the surface structure to be produced on the adhesive layer, and by a nip roll, and where the relief roll and the nip roll rotate in opposite directions, wrapped partly around the relief roll is a web-form carrier material which is guided through the nip and whose speed corresponds more particularly to the peripheral speed of the relief roll, the adhesive polymer mixture, more particularly the self-adhesive polymer mixture, is pressed through the nip, so that the near-roll surface of the polymer mixture is shaped in accordance with the relief, lies in layer form on the carrier material after passage through the nip, and is guided away with the carrier material.
Abstract:
Provided are a pressure-sensitive adhesive having excellent durability and reliability under high-temperature or high-humidity conditions, adhesion strength, workability, re-movability, and the ability to inhibit light leakage; a method for preparing the pressure-sensitive adhesive; a polarizer including the pressure-sensitive adhesive; and a liquid crystal display incorporating the polarizer.
Abstract:
The present invention relates to an adhesive gap sealing tape for sealing the air gaps between the edges of adjacent panels or structural elements against which they abut, the tape comprising a backing having an adhesive layer on one surface and an elongate strip of foam material extending lengthwise along the adhesive layer. In one embodiment, the elongate strip of foam material extending lengthwise along the adhesive layer is provided along a central portion of said adhesive layer. In this arrangement, the portions of backing which extend widthwise beyond the edges of the elongate strip of foam material are foldable to provide foldable flaps which are adapted to overlap and adhere to the respective sides of a panel or structural element so that the foam strip is securable against the edge of said panel or structural element and is sealed on all its sides.
Abstract:
The instant disclosure relates to a screen protective film structure for disposing on an outer surface of an electronic device. The electronic device has a display portion and a frame portion. The screen protective film structure has a light-permitting film and an adhesive portion. The light-permitting film is disposed on one side of the display portion. A central space is formed between the light-permitting film and the display portion. The adhesive portion is connected to the light-permitting film and having a plurality of adhesive protrusions. The adhesive protrusions are abutted to the frame portion, and a gap is formed between the adhesive protrusions. The gap is in communication with the central space and the ambient. Thus, trapped air between the screen protective film structure and the electronic device can be relieved.
