    摘要: A reactive pressure-sensitive adhesive element that includes: i) a carrier layer; ii) a first adhesive layer arranged on a first surface of the carrier layer that comprises a first UV-curable pressure-sensitive adhesive; and iii) a second adhesive layer arranged on a second surface of the carrier layer facing away from the first surface, wherein the second adhesive layer comprises a second UV-curable pressure-sensitive adhesive. Each of the first and second UV-curable pressure-sensitive adhesives, based on a mass of the respective pressure-sensitive adhesive, comprises: x) one or more poly (meth) acrylate compounds in a combined mass fraction from 35% to 85%; y) one or more polymerizable epoxy compounds in a combined mass fraction from 10% to 50%; and z) one or more photoinitiators in a combined mass fraction from 0.1% to 5%. Further, the carrier layer comprises a foam carrier, the foam carrier comprising one or more polyolefins.

    摘要: An inductive gluing sheet is utilized in an induction-assisted adhesive activation method in which the inductive gluing sheet includes a heat-activated adhesive substrate and a conductive substrate embedded therein. When a magnetic field is applied to the conductive substrate through a first surface or a second surface covering the inductive gluing sheet, an electric current is induced in the conductive substrate. The heat created by the electric current transfers to the heat-activated adhesive substrate via conduction and activates the heat-activated adhesive substrate. This allows for direct heating of an adhesive layer through one or more objects and even allows for reversibility of the adhesion setting process.

    摘要: An epoxy-based glue includes an epoxy material, and a solids component including diamond powder and silicon-carbide particles. The adhesive material may be used to form reaction-bonded silicon-carbide bonding reaction-bonded silicon-carbide parts together. The present disclosure also relates to a method of assembling a product from preforms, including locating an adhesive layer, containing diamond powder, between opposed preform surfaces, carbonizing the layer, and infiltrating molten silicon into the preforms and the carbonized layer to convert the preforms into corresponding reaction-bonded silicon-carbide parts, and to convert the carbonized layer into a reaction-bonded silicon-carbide bonding region with a reduced amount of residual silicon. An assembled product, including at least two reaction-bonded silicon-carbide parts bonded together by processing a diamond-containing adhesive, is also disclosed.
