Provided is a sealant sheet that is handled as a laminate with a release liner and can be cured by photoirradiation through the release liner. The release-linered sealant sheet has a photo-curable sealant: sheet, and a release liner placed on at least one face of the sealant sheet. The release liner has a light transmittance of 20% or higher in the wavelength range from 350 nm to 450 non.

Provided is a sealing method that uses a photo-curable sealant sheet. The sealing method provided comprises, in the following order, a step of obtaining a photo-curable sealant sheet, a step of subj ecting the sealant sheet to photoirradiation, and a step of applying the sealant sheet to a target object.

Provided is a sealant sheet that shows reduced elongation during application to a target object. A laminate comprising a sealant sheet is provided. The laminate has a support layer satisfying the formula (1): E′×t≥1×10.sup.4 (N/m). In the formula (1), E′ is the support layer's modulus (MPa) and t is the support layer's thickness (μm).

Embodiments provide methods of assembling apparel products. The methods include applying a composition to a portion of a major component of the apparel product or a portion of a minor component of the apparel product. The methods include coupling the portion of the minor component with the portion of the major component via the composition. 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 an adhesive. The methods include converting the composition to the adhesive. The adhesive including a material having a disulfide bond.

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.

An electrically conductive material includes an anionic polymer having a polymer backbone that is bonded to a plurality of terminal catechol moieties and a plurality of terminal sulfonate moieties. It also includes a cationic polymer including poly(3,4-ethylenedioxythiophene).

A production method of a laminate including a substrate and a light-transmitting support plate that are laminated each other via an adhesive layer and a release layer that is altered through absorption of light, the method including a release layer forming step of coating a reactive polysilsesquioxane on a surface of the support plate, the surface being opposed to the substrate, and heating the reactive polysilsesquioxane to perform polymerization, thereby forming the release layer.

The present invention provides an adhesive film hardly suffering from fisheyes and deposition of dirt and dusts thereonto and having excellent mechanical strength and heat resistance as well as good adhesion properties, which can be suitably used as various surface protective films, etc. The present invention relates to an adhesive film comprising a polyester film and an adhesive layer formed on at least one surface of the polyester film, in which the adhesive layer comprises a resin having a glass transition point of not higher than 0° C., and an antistatic agent, and a thickness of the adhesive layer is not more than 10 μm.

The invention relates to a composition comprising a sulfone-group containing resin obtainable by reaction of a polyamine containing at least one sulfone-group with a polyepoxide and optionally a hardener, as well as adhesives and coating compositions comprising said compositions having gas-barrier properties, methods for bonding substrates using said adhesives and the thus obtained articles as well as the use of the compositions described herein as adhesive or coatings having gas-barrier properties.
