A method of producing a double-sided pressure-sensitive adhesive sheet includes a step of applying a water-dispersed pressure-sensitive adhesive composition onto a release liner to form a coating film, a step of drying the coating film by heating to form a pressure-sensitive adhesive layer, a step of bonding a first surface of a substrate film to an exposed surface of the pressure-sensitive adhesive layer, a step of applying a water-dispersed pressure-sensitive adhesive composition onto a second surface of the substrate film to form a coating film, and a step of drying the coating film by heating to form a pressure-sensitive adhesive layer. A double-sided pressure-sensitive adhesive sheet includes the substrate film with a thickness of 12 μm or less, the first pressure-sensitive adhesive layer on the first surface formed from the water-dispersed pressure-sensitive adhesive composition, the second pressure-sensitive adhesive layer on the second surface formed from the water-dispersed pressure-sensitive adhesive composition, and the release liner in releasable contact with an adhesive surface of the pressure-sensitive adhesive layer.

The curing agent B includes 70 to 90 parts of a linear bifunctional secondary amine curing agent, 10 to 30 parts of a high-melting-point latent curing agent and 1 to 5 parts of an anti-settling agent. A two-stage curing of epoxy bonding oil includes a first-stage curing at room temperature whereby the cured product is in a thermoplastic state and a second-stage curing at 100° C. to 180° C. whereby the cured product is in a thermosetting state. It solves the contradiction between sticking wheels and bonding performance of the bonding layer in field of road and bridge pavement, exploring a new direction for the waterproof bonding layer materials in road and bridge pavement such as steel bridge deck pavement, concrete bridge deck pavement and tunnel pavement.

An adhesive material which comprises an epoxy component including a first flame retardant and a curing component which includes an adhesion promoter and a second flame retardant The epoxy component and curing component are present in a ratio of about 1:1 and the adhesive is formed when the epoxy component is combined with the curing component.

Provided is a PSA sheet having a PSA layer. The PSA layer has a multilayer structure comprising a layer A forming one face of the PSA layer and a layer B placed on the backside of the layer A. The layer B is a photo-crosslinkable PSA layer comprising a photo-crosslinkable polymer.

A multi-layer composition to be located onto a substrate. The composition comprises a bi-layer construction, including a first layer and a second layer, the first layer having a high elastic modulus and tensile strength in comparison to the second layer. The second layer includes a blowing agent such that, when cured, the first layer is spaced away from the substrate. The compositions of the first layer and second layer are similar, thus enabling the reconstitution of scrap into usable material for forming another multi-layer reinforcement.

The present disclosure is generally directed to a method of curing an ionic liquid epoxy mixture using an electromagnetic signal. First, an ionic liquid epoxy resin comprising ionic liquid epoxide monomers and, optionally, diluent epoxy resins and powdered fillers, is combined with a curing agent to form an ionic liquid epoxy mixture. The mixture is then applied as a coating onto a surface of a material. The coating is placed in contact with a second surface of the same material or a surface of another material. An electromagnetic signal, which in some instances is a microwave signal, is applied to the coating. Following application of the signal, the ionic liquid epoxide monomers polymerize and the mixture cures, adhering the surfaces together. Alternately, the epoxy mixture is applied to a surface and cured with microwaves to form a protective coating as in cladding or paint.
