A wafer laminate has an adhesive layer (2) sandwiched between a support (1) and a wafer (3), with a circuit-forming surface of the wafer facing the adhesive layer. The adhesive layer (2) includes a light-shielding resin layer (2a), an epoxy-containing siloxane skeleton resin layer (2b), and a non-silicone thermoplastic resin layer (2c).

A building panel having a substrate and a layer arrangement, arranged on one side of the substrate. The layer arrangement having a surface layer and where the surface layer includes carpet fibres. At least the substrate at least partly includes a mechanical locking device for connecting at least two building panels. Where the substrate and the layer arrangement each includes a polymer of the same type of polymer.

A method to produce a panel. The method includes providing a core having a first surface, providing a surface layer including a substantially uncured amino resin, applying an hydrolysable adhesive on the first surface of the core and/or on a surface of the surface layer adapted to face the core, arranging the surface layer on the first surface of the core, pressing the surface layer to the core to form a panel by applying heat and pressure in a press, thereby adhering the surface layer to the core by the hydrolysable adhesive and curing the amino resin of the surface layer. Also such a panel.

Disclosed is a method of making a conductive material or active material that includes graphene or other 2-D materials. The method includes obtaining a layered stack. The layered stack including one or more conductive materials or 2-D materials separated by a metal layer, and one or more substrate materials. The stack can be subjected to a metal removal process to obtain two conductive or active materials. A first conductive or active material can include a first substrate layer attached to the first active layer. The second conductive or active material can include a second substrate layer attached to the second active layer. The first and second active layers can be conductive graphene layers.

In one aspect of the present subject matter, a method of forming a linear panel includes drawing a multi-layer panel material assembly having differing inner and outer material layers along a processing path. The method also includes heating the panel material assembly. In addition, the method includes forming the heated panel material assembly into a desired shape as the assembly is drawn along the processing path. Additionally, in another aspect of the present subject matter, a linear panel includes a body formed from a multi-layer panel material assembly having differing inner and outer material layers.

A manufacturing procedure for ceiling trims for vehicles, the structure of which comprises at least one first coating sheet and at least one second coating sheet that extend along one of the sides of the first sheet, joined via a layer of heat-stable polyurethane adhesive, comprising a step of applying a gas-phase catalyst on such sheets through a thermoforming mould that starts before the mould is completely closed and ends before the mould is completely opened. As a result of said application of a gas-phase catalyst we prevent the use of demoulding agents to facilitate extraction of the ceiling trim formed inside the mould.

The present invention relates to a thermally activatable adhesive composition for use in a method for producing a stack of metal sheets from glued together sheet metal components, the use of the adhesive composition in a method for producing a stack of metal sheets from glued together sheet metal components, the method for producing a stack of metal sheets from glued together sheet metal components, a sheet metal component coated with the adhesive composition, and a stator or rotor core containing one or more of such sheet metal components.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, a method of forming an insulation product may include forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper. The method may also include immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.

A method, apparatus, and system for reticulating an adhesive on a workpiece. The workpiece may be perforated with a plurality of passages that extend through a first side to a second side. To reticulate an adhesive on the first side of a workpiece, a flow of heated fluid is provided through a nozzle. The nozzle provides the fluid at a first pressure to a first group of the perforations. Once the temperature at the first side of the workpiece reaches a specified range, the fluid pressure may be increased or otherwise set in order to clear the perforations by forcing the adhesive out of or away from each of the perforations. Temperature of the adhesive, pressure within the nozzle, and/or light passage through the perforations may be monitored for logical control or quality assurance.
