A release liner having filaments contacted to a major side thereof, then pressed thereinto. The filaments may be a thermoplastic or thermoset type material.

The invention provides a composite capable of achieving both excellent followability to an adherend and excellent adhesion. The composite has a support and a plurality of structures fixed to at least one surface of the support, and the structure has a shaft member consisting of a flexible material extending from a proximal end fixed to the support, and an adhesive part arranged at a distal end of the shaft member.

Core-sheath filaments comprising a non-tacky sheath, the non-tacky sheath exhibiting a melt flow index of less than 15 grams per 10 minutes and an adhesive core, the adhesive core comprising 10 wt.% to 99 wt.% of a polymer and a phenolic resin, where the polymer comprises an isoprene moiety, the phenolic resin comprises an alkyl-substituted phenol, and the phenolic resin is substantially free of halogens. Cured adhesive composition comprising the disclosed core-sheath filaments and methods of making such core-sheath filaments.

Methods for producing an adhesive filament from a pressure-sensitive adhesive, devices for carrying out the methods, adhesive filaments, adhesive rollers, and printed elements are provided. The methods comprise providing the pressure-sensitive adhesive; forming the pressure-sensitive adhesive to a material strand and treating at least a partial region of the surface of the material strand with a plasma stream.

A variety of adhesive laminates are described, many of which perform functions such as liquid indication, outgassing, liquid retention, electrical conducting, and sound channeling. Also described are adhesive regions on face materials in which the regions exhibit particular dimensional proportions. Methods involving direct and transfer coating of adhesives are also described. In a particular version, a method of roll to roll transfer coating of sprayed pressure sensitive adhesives is described. Also described are various adhesive films and laminates many of which can be produced using the methods.

The present disclosure provides a core-sheath filament. The core-sheath filament includes an adhesive core and a non-tacky sheath, wherein the sheath exhibits a melt flow index of less than 15 grams per 10 minutes. The present disclosure also provides a method of printing an adhesive. The method includes a) melting a core-sheath filament in a nozzle to form a molten composition, and b) dispensing the molten composition through the nozzle onto a substrate. Steps a) and b) are carried out one or more times to form a printed adhesive. The core-sheath filament includes an adhesive core and a non-tacky sheath. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process using a core-sheath filament, the article including a printed adhesive based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article including a printed adhesive, using a core-sheath filament.

The present invention relates to an adhesive article including a linear adhesive body and a non-adhesive layer covering a longitudinal direction surface of the adhesive body, wherein the adhesive article expresses adhesiveness when the non-adhesive layer is broken by stretching the adhesive article.

A composite hot-melt adhesive mesh film and preparation process thereof, in particular, a composite hot-melt adhesive mesh film and preparation process thereof for bonding metal and non-polar material are disclosed. The mesh film is compounded of a polar polyamide hot-melt adhesive and a non-polar polyolefin hot-melt adhesive mesh film containing a compatibilizer. The mesh film has a high adhesive strength and a durable and stable adhesion, and is especially suitable for bonding stainless steel, aluminum, copper or other metal materials and polyethylene, polypropylene or other non-polar polymers. Additionally, the preparation process is completed in one set of production process from raw material pretreatment to the final preparation of the hot melt adhesive mesh film product, thereby greatly reducing production failures, and providing high production efficiency and low costs.

An embodiment of the present invention relates to a bonded object or a method for manufacturing a bonded object, the bonded object having bases bonded therein while placing an adhesive layer in between, the adhesive layer being obtained from a fluororubber composition that contains at least one fluororubber selected from fluoroelastomer (FKM) and perfluoroelastomer (FFKM), and has a Mooney viscosity (ML 1+10) at 121? C., measured in accordance with ASTM D1646, of 80 to 115.

Disclosed herein are systems, devices, and method for forming self-adhesive single or multilayer fibrous media.
