Disclosed is a protective film, which includes: a protective film sheet; a protective layer; and a release layer, a lead tab is connected to an end part of the release layer, and a positioning mechanism is arranged on the protective layer to align the protective film sheet with a screen of an electronic device.

Embodiments provide methods of disassembling an apparel product. The methods include exposing an adhesive of the apparel product to electromagnetic energy. The adhesive is disposed at least partially between a major component and a minor component of the apparel product. The adhesive includes a polymer having a cyclodextrin moiety bonded to an azobenzene moiety. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.

Embodiments provide methods of disassembling apparel products. The methods include exposing an adhesive of the apparel product to a composition. The adhesive is disposed at least partially disposed between a major component and a minor component of the apparel product. The adhesive includes a material having an imine bond or an iminium bond. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component via the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.

The present invention is directed to a curable and one component (1K) debondable adhesive composition comprising: a) epoxy resin; b) a curing agent for said epoxy resin; c) an electrolyte; and, d) an electrically non-conductive filler; wherein said composition comprises at least one of: e) a combination of a solubilizer and a toughener; and, f) electrically conductive particles.

One aspect of the present invention provides a composite sheet which comprises a nitride sintered body having a porous structure and a semi-cured product of a thermosetting resin composition impregnated into the nitride sintered body, the line roughness Rz specified by JIS B 0601:2013 of at least one main surface being 10 μm or less.

The invention provides an adhesive composition containing an adhesive component (S) and a release component (H) formed of a polyorganosiloxane having a complex viscosity of 3,400 (Pa.Math.S) or higher.

A method for recycling of packaging material is disclosed. The packaging material comprises a multilayer material (10) comprising a metal layer (30) and at least one polymer layer (20, 40). The method comprises placing the packaging material in a vat (310) comprising a separation fluid (330) to produce a mixture of metal shreds from the metal layer (30), plastic shreds from the polymer layer (20, 40) and residual components. The separation fluid comprises a mixture comprising a mixture of water, a short-chained carboxylic acid, phosphoric acid and an alkali metal hydroxide solution.

A method for separating a temporarily bonded substrate stack by bombardment of a joining layer of the substrate stack by means of laser beams emitted by a laser, characterised in that laser beams of the laser reflected and/or transmitted at the temporarily bonded substrate stack are detected during the bombardment of the joining layer with the laser beams. The invention also relates to a corresponding device.

A suction holder for sucking and holding a holding target member includes a sucker, a tube bellows connected to a lower end of the sucker, and a tube arranged inside the tube bellows and having an upper end positioned lower than an upper end of the sucker. A lower opening of the tube is communicated with a suction source and the holding target member is contacted with the upper end of the sucker to form a closed room, and the inside of the closed room is placed into a negative pressure state to hold the holding target member.
