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:
A process increases adhesion between a layer of pressure-sensitive adhesive and a substrate, wherein the layer of pressure-sensitive adhesive has a first surface facing away from the substrate and a second surface facing toward the substrate and a third surface of the substrate. The process treats (i) the second surface of the layer of pressure-sensitive adhesive that faces toward the substrate and (ii) the third surface of the substrate with atmospheric-pressure plasma, and adhesive bonds the layer of pressure-sensitive adhesive to the third surface of the substrate.
Abstract:
An adhesive tape for jacketing an elongated item, more particularly cable sets, comprises a tapelike carrier which is characterized in that the tapelike carrier is provided on at least one side with a binder which is thermally softenable at a temperature of 50° C. to 100° C. and comprises a polycaprolactone.
Abstract:
The invention relates to a pressure-sensitive adhesive strip containing at least one layer SK1 of a self-adhesive composition based on vinylaromatic block copolymer and containing tackifying resin, wherein the vinylaromatic block copolymer contains at least one polymer block A formed predominantly by polymerization of vinylaromatics, and simultaneously contains at least one polymer block B formed predominantly by polymerization of conjugated dienes, where the proportion of 1,2-bonded conjugated diene in the B block is less than 30% by weight, preferably less than 20% by weight. The invention also relates to a pressure-sensitive adhesive strip of this kind, in which at least layer SK1 has been subjected to irradiation with electrons.

Abstract:
The invention relates to an adhesive strip which can be detached substantially on the adhesion plane in a residue-free and nondestructive manner by stretching, said strip consisting of one or more adhesive material layers and optionally one or more intermediate carrier layers, at least one of the adhesive materials layers containing at least one filler, the primary particles of which can be individually separated, wherein the primary particles (i) are substantially spherical and (ii) have an average diameter d(0.5) of less than 10 μm, and the ratio of the average diameter d(0.5) of the primary particles to the thickness of the adhesive material layer in which the primary particles are contained is less than 1:2. The invention also relates to the production and use of said adhesive strip.
