    Abstract: The present invention relates to an adhesive tape and to a method for jacketing an elongated item, more particularly cable sets. The adhesive tape must cure within the operational dictates for further processing, e.g. within 6 min, and after curing must exhibit the required dimensional stability properties. However, the adhesive compositions must not cure during storage itself, since otherwise they can no longer be used. Nor may the curing temperatures be too high, since otherwise the lead insulation, which is often made of PVC, may suffer damage. The invention proposes a method for jacketing an elongated item such as more particularly leads or cable sets, where a tape which comprises a moisture-curing binder on a carrier is first impregnated with water and immediately thereafter is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the adhesive tape, the elongated item together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition, while the curable adhesive cures. Alternatively proposed is a method for jacketing an elongated item such as more particularly leads or cable sets, where a tape which comprises a moisture-curing binder on a carrier is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the adhesive tape, the elongated item together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition, and the curable adhesive is brought to cure by the supply of moisture.

    Abstract: The present invention relates to an adhesive tape and to a method for jacketing an elongated item, more particularly cable sets. The adhesive tape must cure within the operational dictates for further processing, e.g. within 6 min, and after curing must exhibit the required dimensional stability properties. However, the adhesive compositions must not cure during storage itself, since otherwise they can no longer be used. Nor may the curing temperatures be too high, since otherwise the lead insulation, which is often made of PVC, may suffer damage. The invention provides a method for jacketing an elongated item such as more particularly leads or cable sets, where a stretched shrink-wrap film is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the stretched shrink-wrap film, the elongated item together with the shrink-wrap film wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition and the shrink-wrap film is brought to shrink by the supply of thermal energy at a temperature of up to 130° C.

    Abstract: The aim is to provide an efficient method for producing a multi-layer adhesive tape having a heat-sealing layer and a pressure sensitive adhesive that results in effective composite adhesion of the individual layers to one another. This is accomplished with a method for producing an adhesive sealing tape covered with a release liner, said method comprising a) heating a pressure-sensitive adhesive in such a way that the pressure-sensitive adhesive is present as a melt; and b) producing a composite in a roll nip in such a way that a hotmelt adhesive layer is lying on one roll, a release liner is lying on the other roll, the release liner having an outer release layer, and this outer release layer pointing away from the roll surface, the pressure-sensitive adhesive melt is introduced into the roll nip and by rotation of the rolls, contacting of the layers and cooling, a composite is obtained with the sequence of hotmelt adhesive layer—pressure-sensitive adhesive—release liner, the release liner remaining on the pressure-sensitive adhesive until the adhesive tape is applied.

    Abstract: The invention relates to an extensively biologically degradable adhesive tape, which in particular has a good and quickly established anchoring between the adhesive and the carrier. The invention relates to an adhesive tape for protecting surfaces, comprising an adhesive H, containing at least 60 wt %, at least one polyurethane P, obtainable from chemical cross-linking of a polyurethane pre-polymer, obtainable from the chemical reaction of d) one or a plurality of aliphatic polyester polyols A having a hydroxy functionality of 1.8 through 2 and a number-averaged molecular weight of equal to/greater than 1,000 g/mole; e) one or a plurality of compounds B having a hydroxy functionality of 1.8 through 2 and a number-averaged molecular weight of less than 1,000 g/mol; f) one or a plurality of aliphatic diisocyanates C; wherein the ratio of the total number of isocyanate groups to the total number of hydroxy groups of the substances involved in the chemical reaction for building the prepolymer is greater than/equal to 0.4 and less than 1; and a biodegradable carrier.

    Abstract: The invention relates to a method for jacketing elongate articles, such as lines or cable harnesses in particular, by means of an adhesive tape comprising a tape-shaped substrate, which substrate has, on at least one side, a thermally curable, meltable, preferably pressure-sensitive adhesive layer, the adhesive layer comprising an epoxide-functionalized acrylonitrile-butadiene copolymer which has on average more than 1.5 epoxide groups per molecule and comprising the reaction product of phthalic anhydride and diethylene-triamine, the adhesive tape being led in a helix around the elongate article or the elongate article being enveloped by the adhesive tape in the axial direction, the elongate article together with the enveloping adhesive tape being brought into the desired arrangement, in particular into the cable harness plan, the elongate article being held in this arrangement, and the curable adhesive mass being cured by supplying thermal energy, in particular at a temperature of up to 110° C.
