    摘要: The present application provides a two-component adhesive composition. Specifically, the two-component adhesive composition comprises 1.5-18 parts by weight of an epoxy resin, an effective amount of a peroxide oxidant, an effective amount of a reducing agent, 22-37 parts by weight of methyl methacrylate, 4-15 parts by weight of tetrahydrofurfuryl acrylate and/or propoxylated tetrahydrofurfuryl acrylate, and 8-19 parts by weight of a free radical reactive acrylate oligomer, wherein the two-component adhesive composition comprises a part A and a part B, the part A comprises the peroxide oxidant, the part B comprises the reducing agent, and the epoxy resin, methyl methacrylate, tetrahydrofurfuryl acrylate and/or propoxylated tetrahydrofurfuryl acrylate and the free radical reactive acrylate oligomer exist in one or two of the part A and the part B. The two-component adhesive composition has good bonding performance to polybutylene terephthalate composite materials and metal materials (especially aluminum materials).

    摘要: The invention relates to on-demand debondable pressure sensitive adhesive and laminating adhesive compositions and uses thereof. The debondable pressure sensitive adhesives and laminating adhesives are applied onto a substrate to form a bond, and upon exposure to electron beam or UV light energy source, the adhesive can dissociate from the substrate. The debondable pressure sensitive adhesives and laminating adhesives are particularly suitable for recycling in a circular economy.
