Abstract: The invention relates to a perforated adhesive film (16) that will be used to glue a wall on one face of a cellular structure (10) to form a sandwich panel. The adhesive film (16) comprises at least one hole and not more than three holes (18) facing each of the cells (12) of the cellular structure (10). Preferably, the holes (18) are formed by punching an unperforated adhesive film. The holes (18) enable the formation of regular glue dabs on the ends of the partitions (14) separating cells (12) in the cellular structure (10), when the adhesive film (16) is heated before the wall is glued.

Abstract: A vapor permeable, water impermeable film is coating partially with an adhesive surface coating. The partial adhesive coating is deposited on both surfaces of the film and coated areas on one surface of the film are at least partially in line with the coated areas of the second surface.

Abstract: The present invention relates to an acrylic pressure-sensitive adhesive composition containing an acrylic polymer and a tackifier obtained by acid modification of a tackifier resin inherently free of an acid component; a pressure-sensitive adhesive tape including a substrate made of a film comprising an olefin polymer or a thermoplastic resin containing a carbonyl oxygen atom in the molecular skeleton, and the acrylic pressure-sensitive adhesive composition on at least one surface of the substrate, and the like. The invention provides an acrylic pressure-sensitive adhesive composition having high adhesive strength (particularly initial adhesive strength) to an adherend having lower polarity, such as an olefin polymer heretofore been considered poorly adhesive, wherein degradation of the adhesive strength after heating and preservation has been suppressed, as well as a pressure-sensitive adhesive tape comprising the composition.
Abstract: A wall patch includes a body with a lower surface and an upper surface. An adhesive is located on the lower surface to secure the wall patch to a wall surface. The upper surface is ready-to-paint and can also be pre-textured, if desired. A center reinforcement can be a rigid plastic or metal wall patch, or a flexible plastic or fibered paper wall patch, without a textured upper surface. A method for repairing a hole in a wall includes placing a wall patch over the hole and directly painting the upper surface of the wall patch. The method can further include placing a center reinforcement over the hole before applying the wall patch.
Abstract: An adhesive for an at least one-layer pressure sensitive adhesive sheet strip which is residuelessly and nondestructively redetachable by extensive stretching substantially in the bond plane, said adhesive being composed of at least one block copolymer having one or two end blocks composed of vinylaromatics, and a block composed of a conjugated diene, wherein the fraction of 1,2-linked diene is selectively hydrogenated.
Abstract: This invention relates to labels. In one embodiment, the labels comprise (A) a polymer film comprising a styrenic polymer, said film having an upper surface and a lower surface, and an MVTR of from about 15 to about 150 g/m2/day, and (B) a water-based adhesive in contact with the lower surface of the film. These labels can be bonded to substrates of glass, plastic or metal using the water based adhesive.

Abstract: A wall patch includes a substantially planar body, an adhesive located on a first surface of the body, a ready-to-paint second surface of the body, and an aperture in the body. The aperture is preferably sized to minimize a wall hole, such as is commonly made for installation of an electrical outlet or other household wall element. A method for repairing a wall hole includes identifying a wall hole to be repaired by covering less than a total hole area defined by the wall hole, said wall hole having a wall element mounted therein; applying over the wall hole a wall patch having a substantially planar body, an adhesive located on a lower surface of the body, a ready-to-paint upper surface of the body, and an aperture in the body having an aperture area less than the wall hole area; wherein the aperture of the wall patch partially covers the wall hole without obstructing access to the wall element; and painting directly over the wall patch.
Abstract: An adhesive and a pressure-sensitive transfer adhesive tape formed by coating the adhesive on a base material are provided. The adhesive has a color when applied to a substrate and, after application can be decolored. The adhesive comprises a colored material colored by reacting a leuco dye with a developer, a material (decoloring material) having a decoloring effect by acting on the colored material, and microcapsules including a material allowing both of the colored and decoloring materials to react by acting on at least one of them.
Abstract: The present invention provides a functional film for transfer in order to furnish a surface of an article, even an article poor in flexibility, such as a board material, with a functional layer having a uniform thickness and a higher function, e.g. a transparent conductive layer having a lower electric resistance; an article furnished with the functional layer; and a method for producing the article furnished with the functional layer. A functional film for transfer comprising at least a functional layer 4 on a support 1, said functional layer 4 being releasable from the support 1, wherein the functional layer 4 is a compressed layer of functional fine particles, and further, on the functional layer 4 an adhesive layer 5 comprising at least an acrylic type monomer (M) and a silicone type resin (S) is provided.
Abstract: The film splicer includes a base body on which two films to be spliced are aligned such that splicing ends thereof make contact with each other, an adhesive tape applied to the splicing ends of the films to join them, and a splicer arm that is folded against the base body to bore sprocket holes by punching members and to cut the adhesive tape by cutting members to a length corresponding to the length in the width direction of the films, wherein the cutting members comprise punches that are capable of punching out both the adhesive tape and excessive edge areas in the width direction of the films and that are formed with tapered portions having an angle relative to a cutting direction that extends in the longer direction of the films, the tapered portions being formed at both end areas in the cutting direction, whereby edge areas in the width direction of the films spliced together are free of steps.
Abstract: A protective tape used for optical member comprising a plastic film base, a pressure-sensitive adhesive layer formed on one side of the plastic film base and a treated layer formed on an opposite side of the plastic film base, wherein the treated layer has a structure in which a copolymer (A) including (a) an alkyl (meth)acrylate having an alkyl group with carbon numbers of 8 to 20; (b) (meth)acrylonitrile; and (c) a monomer having functional groups copolymerizable with the component (a) and the component (b), as copolymerization components, is cross-linked by a cross-linking agent.
