Abstract: A process for producing a three-dimensional pressure-sensitive adhesive product (HKP) from radiation-induced reactive prepolymer composition (SRP), comprising the process steps: a. providing a negative mold (NF) for the pressure-sensitive adhesive product (HKP), b. filling the negative mold (NF) provided with the radiation-induced reactive prepolymer mass (SRP), c. radiation-induced chemical conversion of the prepolymer mass (SRP) to the pressure-sensitive adhesive product (HKP), and d. removal of the pressure-sensitive adhesive product (HKP) from the negative mold (NF). In order to overcome the disadvantages of conventional technology, the negative mold (NF) is produced by a thermoforming process using a positive mold (PF), a casting process for the radiation-induced reactive prepolymer mass (SRP) is used to fill the negative mold (NF) provided, and cooling (K) takes place during the radiation-induced chemical conversion of the prepolymer mass (SRP) to the pressure-sensitive adhesive product (HKP).

Abstract: A method for manufacturing a pressure-sensitive self-adhering adhesive is based on an alkoxylated silane-containing polymer, to which is added at least one tackifying resin compatible with the alkoxylated, silane-containing polymer, and at least one catalyst (K). To overcome various disadvantages of the prior art, such as a too-slow or excessively violent reaction of the alkoxyl groups, and the need for an additional supplying of water, the alkoxylated silane-containing polymer is crosslinked using a catalyst (K) that comprises a Lewis acid-base adduct, wherein the Lewis acid (LS) is a reaction-inhibited cation at least in the temperature range below 60° C., and the Lewis base (LB) is an anion of a very strong acid. In a preferred embodiment the Lewis acid (LS) is an organyl-group-containing (AG) halogen-onium cation, and the Lewis base (LB) is the anion of a superacid.
