Abstract:
The invention relates to a double-sided adhesive tape having a first outer impact-adhesive side and a second outer side that can be heat activated, comprising an at least two-layer product structure comprising the layers A and B. Layer A is an impact-adhesive layer chemically cross-linked by means of thermal initiation or an impact-adhesive carrier layer chemically cross-linked by means of thermal initiation. Layer B is a layer on the basis of a thermoplastic plastic. Layer A and layer B are in direct contact with each other, and the surface of layer B that is in direct contact with layer A has been corona- or plasma-pretreated. The double-sided adhesive tape is characterized in that the corona or plasma pretreatment is performed in an atmosphere comprising nitrogen, carbon dioxide, or a noble gas or a mixture of at least two of said gases.
Abstract:
Adhesive tape having at least two layers A and B laminated directly on one another, with at least one or both layers A or B being an adhesive, and the interfaces of the layers A and B laminated on one another being subjected to a physical method, the physical method being selected from the group consisting of corona discharge, dielectric barrier discharge, flame pretreatment and plasma treatment, before the layers are laminated to one another, with the two methods differing from one another.
Abstract:
The present invention relates to a pressure-sensitive adhesive tape comprising or consisting of a moisture-curing composition comprising or consisting of: A 5 to 60 parts by weight of at least one film-former component; B 40 to 95 parts by weight of at least one epoxide component; C 10 to 500 parts by weight of at least one moisture-activatable curing agent; D optionally 0.1 to 15 parts by weight of at least one stabilizer, and E optionally 0.1 to 200 parts by weight of at least one additive, based in each case on the moisture-curing composition, with the parts by weight of components A and B adding up to 100 and with the moisture-curing composition being characterized in that the moisture-activatable hardener C comprises or consists of at least one blocked amine. The invention further relates to a method for assembling two components using such adhesive tape.

Abstract:
The present invention relates to a flexible, pressure-sensitively adhesive sheetlike structure for improved structural bonding, more particularly for clearance compensation, of diverse materials, such as metal, wood, glass and/or plastic, for example.
