Abstract: The invention describes a double-sided, carrierless self-adhesive tape which can be used in particular for achieving very durable adhesive bonding of a variety of articles. This double-sided, carrierless self-adhesive tape is composed of a homogeneously crosslinked pressure-sensitive acrylate hotmelt composition of single-layer construction, which may have been lined with release materials such as siliconized release papers or release films. The double-sided, carrierless pressure-sensitive adhesive tape is characterized in that it is composed of a photoinitiator-free, thermally homogeneously crosslinked acrylate hotmelt which is crosslinked predominantly by way of urethane units. It is notable in particular for the fact that it is homogeneously chemically crosslinked through the layer and, in contrast to acrylate layers crosslinked by radiation (UV/EBC), does not exhibit any profile of crosslinking through the layer. It can be used in particular as an adhesive transfer tape for the permanent attachment of articles to a variety of substrates.

Abstract translation: 本发明描述了一种双面无载体自粘胶带，其特别可用于实现各种制品的非常耐用的粘合剂粘合。 这种双面无载体自粘胶带由单层结构的均匀交联的压敏丙烯酸酯热熔组合物组成，其可以衬有剥离材料如硅化剥离纸或脱模膜。 双面无载体压敏粘合带的特征在于其由不含光引发剂的热均匀交联的丙烯酸酯热熔体组成，主要通过氨基甲酸酯单元交联。 特别值得注意的是，它通过该层均匀化学交联，与通过辐射（UV / EBC）交联的丙烯酸酯层相反，通过该层不显示任何交联轮廓。 它可以特别用作粘合剂转移带，用于将制品永久地附着到各种基材上。
