Herein are disclosed a pressure-sensitive adhesive layer on a substrate, the adhesive layer containing stripes of first and second pressure-sensitive adhesives. The surface of the adhesive layer that faces the substrate is surface-enriched with the first pressure-sensitive adhesive. Methods of making are disclosed.

Pressure-sensitive adhesive layers with surface-enriched stripes and methods of making

An article including a release liner with an adhesive layer disposed thereon, the adhesive layer including a plurality of stripes of a first pressure-sensitive adhesive and of a second pressure-sensitive adhesive, arranged in a generally alternating pattern. The first pressure-sensitive adhesive is a silicone-based pressure-sensitive adhesive that includes a silicone block copolymer elastomer comprising hard segments that each comprise at least one polar moiety, and the second pressure-sensitive adhesive is an organic polymeric pressure-sensitive adhesive.

Article comprising pressure-sensitive adhesive stripes

A duct for distributing one or more telecommunication lines comprises an elongated body having a length and a conduit portion with a lengthwise bore formed therein. The conduit portion contains one or more telecommunication lines. The duct also includes a flange extending lengthwise adjacent the main body to mount the duct to a mounting surface, such as a wall. The duct also includes an adhesive layer disposed on a surface of the flange, the adhesive layer comprising a removable adhesive to permit removal of the duct from the mounting surface after mounting.

Removable adhesive backed ducts for cabling and a removal method

A multi-layer assembly that includes a release liner, a first layer disposed on the release liner, the first layer including a pressure-sensitive adhesive composition that includes a silicone polymer that includes silicone polyurea block copolymers, polydiorganosiloxane polymers, or combinations thereof, a second layer disposed on the first layer, the second layer including a composition that includes an elastomer, the composition of the second layer being different from the pressure-sensitive adhesive composition of the first layer, the first layer of the multi-layer assembly exhibiting a release force to the release liner of no greater than 100 gram per 0.5 inch width after the multi-layer assembly has been stored for 46 days at 120&#xb0; F.

Multi-layer assembly, multi-layer stretch releasing pressure-sensitive adhesive assembly, and methods of making and using the same

An adhesive tape that is stretch releasable, articles that contain the adhesive tape, and uses of the adhesive tape are disclosed. The adhesive tapes include a backing layer that is adjacent to at least one pressure-sensitive adhesive layer. The backing layer typically is optically clear and includes a poly(alkylene) copolymer. The pressure-sensitive adhesive layer is a silicone-based adhesive composition. In many embodiments, the adhesive tape is optically clear.

Stretch releasable adhesive tape

An adhesive tape that is stretch releasable, articles that contain the adhesive tape, and uses of the adhesive tape are disclosed. The adhesive tapes include a backing layer that is adjacent to at least one pressure-sensitive adhesive layer. The backing layer typically is optically clear and includes a poly(alkylene)copolymer. The pressure-sensitive adhesive layer is a silicone-based adhesive composition. In many embodiments, the adhesive tape is optically clear.

A horizontally mounted shelf assembly includes an elongated support rail, at least one accessory slidaby connected with the support rail, and at least one stretch releasing adhesive strip arranged between the support rail and a wall for securing the shelf assembly to the wall. Each accessory may also be separately mounted on the wall using stretch releasing adhesive strips.

Horizontally mounted shelf assembly and accessories therefor

A wall mountable shelf assembly includes an elongated support rail, at least one accessory slidably connected with the support rail, and at least one stretch releasing adhesive strip arranged between the support rail and the wall for securing the shelf assembly to the wall.

Vertically mounted shelf assembly and accessories therefor

A method of making a pressure-sensitive adhesive assembly, the method including coating a pressure-sensitive adhesive composition that includes a silicone polymer on a first major surface of a first release liner to form a first layer, coating a composition on the first layer to form a second layer, the composition of the second layer including an elastomer, at least one of the pressure-sensitive adhesive composition of the first layer and the composition of the second layer being in an uncured state during the coating of the second layer, and curing at least one of the first layer and the second layer, the first pressure-sensitive adhesive composition of the multi-layer assembly exhibiting a release force to the release liner of no greater than 100 gram per 0.5 inch width after the multi-layer assembly has been stored for 46 days at 120&#xb0; F.

Methods of making a pressure-sensitive adhesive assembly

Conformable pressure-sensitive adhesive tapes which comprise a layer of polymeric foam in the backing and may be adhered firmly to a substrate and thereafter removed therefrom after only being stretched at an angle no greater than about 35&#xb0; from the surface of the substrate. Articles for mounting an object such as a picture to a surface such as a wall comprising a pressure-sensitive adhesive tape of the invention are also described.

Removable foam adhesive tape

A stretch releasing adhesive article for mounting on a wall surface includes an elongated stretch releasing adhesive strip having a first major surface with a non-adhesive contact surface adjacent the first end, and a backplate having a first major surface including a protrusion arranged in overlapping relation with the adhesive strip non-adhesive contact surface that serves to concentrate a force applied by a user in the region of the first end of the backplate in the region of the non-adhesive contact surface of the adhesive strip. A method of adhesively mounting an item to, and removing an item from, a wall surface that is susceptible to damage without damaging the surface is also disclosed.

Stretch releasing adhesive article for fragile surfaces

A pressure indicating structure comprising (1) a translucent or transparent sheet including reflective structure defining at least a portion of a second surface of that sheet for reflecting back through a first opposite surface of the sheet light entering the sheet through its first surface, that reflective structure comprising a multiplicity of peak portions and recessed portions having recessed surface portions of the second surface that define recesses from the peak portions; and (2) a deformable layer comprising pressure sensitive adhesive having a major surface along the second surface of the sheet over the peak portions of the reflective structure. A predetermined pressure between the first surface of the sheet and the surface of the deformable material opposite the reflective structure can deform the pressure sensitive adhesive into the recesses to wet part or all of the recessed surface portions of the reflective structure thereby causing light to pass through the second surface along the wetted recessed surface portions instead of being reflected, which is visually observable to indicate that the predetermined pressure has been applied.

Pressure indicating structure

A stretch releasing pressure sensitive adhesive tape includes a silicone pressure sensitive adhesive composition that exhibits a 180&#xb0; peel strength on a glass substrate at 98% relative humidity of at least about 5.47 N/dm and a non-tacky tab. A stretch releasing pressure sensitive adhesive tape includes a pressure sensitive adhesive composition having a modulus at 1 radian/second and &#x2212;17&#xb0; C. of no greater than about 1&#xd7;10Pa and a non-tacky tab.
