Peel-away tape includes a double-sided adhesive tape with a perforated design and a peel-away backing that includes liftable tabs to assist in the removal thereof. In an exemplary embodiment, the tape and peel-away backing is perforated on equidistant intervals. A small tab located at the center of each perforation extends over the perforation line which, when separated, extends outward where it can be grasped.

A sticking component that includes: a sheet-shaped adhesive component having first and second sticking surfaces with adhesiveness opposed to each other, the first sticking surface constructed to be removably adhered to a bottom surface of a stick-on biometric device; a first release component removably adhered to the first sticking surface of the sticking component; and a second release component removably adhered to the second sticking surface of the sticking component, wherein at least one of the first release component or the second release component has an outline that is visible, and that, when the sticking component is to be adhered to the stick-on biometric device, at least partially overlaps an outline of the bottom surface of the stick-on biometric device in a plan view of the sticking component.

Described herein are methods of forming uncured sealant assemblies and also methods of forming seals between various parts using such assemblies. In some examples, an uncured sealant assembly comprises two protective layers and an uncured sealant layer, disposed in between. The uncured sealant assembly is stored and provided at a cure-inhibiting temperature, selected to minimize the curing rate of the uncured sealant layer. The size and the shape of the uncured sealant layer are specifically selected to ensure the complete coverage of the faying surfaces, filling of all gaps and voids between the faying surfaces, and controlling the shape and size of uncured sealant squeeze out between the faying surfaces. In some examples, the size and shape of the uncured sealant layer maybe be specifically selected to have no uncured sealant squeeze out between parts.

A threadlike adhesive sticking apparatus of the present invention is a threadlike adhesive sticking apparatus configured to press a threadlike adhesive wound in a roll shape together with a release liner against an object while feeding out the threadlike adhesive, and includes a pressing unit configured to press the threadlike adhesive debonded from the release liner against the object. A compression elastic modulus of the release liner is 1.5 MPa or less.

The present invention provides an optically clear adhesive sheet having excellent environment resistance using a heat-curable polyurethane composition that has excellent flexibility and is capable of giving a thick film. The optically clear adhesive sheet of the present invention is formed of: a cured product of a heat-curable polyurethane composition, the heat-curable polyurethane composition containing a polyol component, a polyisocyanate component, and a tackifier, the polyol component having an olefin skeleton, the polyisocyanate component being a modified polyisocyanate that is obtained by reacting an acyclic aliphatic and/or alicyclic polyisocyanate containing an isocyanate group with an ether compound containing an ethylene oxide unit.

The present invention relates to a multi-region foldable adhesive film and a fabrication method therefor, and particularly, to a multi-region foldable adhesive film having improved folding characteristics by making an adhesive layer included in the foldable adhesive film have different physical properties, and a fabrication method therefor.

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.

The disclosure provides a micro-groove drag reduction flexible film and a preparation method thereof. The micro-groove film has a triangular groove structure on the upper surface along the direction of an air flow, and an adhesive layer on the lower surface for quick adhesion to an aircraft surface. After the surface of the aircraft is covered with a micro-groove film, it could limit the spanwise movement of the bottom air at the boundary layer of the aircraft surface, improve the flow field characteristics of the aircraft near the wall, and effectively reduce the frictional resistance of the wall. The micro-groove flexible film is prepared by a roller hot pressing method. The triangular groove structure is processed on the surface of the mold roller of the double roller hot press. After pretreatment of the thermoplastic polyurethane (TPU) polymer film, a micro-groove structure is hot-pressed on the surface of the TPU film.
