摘要:
The invention relates to a polyacrylate which as a result of a polymerization process has a broad, bimodal molecular weight distribution. These acrylate pressure-sensitive adhesives are preferably processed from the melt. The low molecular weight fraction lowers the flow viscosity, while the high molecular weight fraction results in the achievement of a high shear strength, following appropriate crosslinking, for the acrylate pressure-sensitive adhesive.

摘要:
A heat-activatedly bondable, substantially two-dimensional (“2D”) diecutting element having a carrier, a first adhesive coating and a second adhesive coating is presented, its carrier taking the form of a carrier film having a first side and a second side, its first adhesive coating being disposed on the first side of the carrier film and comprising at least one heat-activable adhesive, and its second adhesive coating being disposed on the second side of the carrier film and comprising at least one heat-activable adhesive. The carrier film here has, over its two-dimensional extent, a multiplicity of openings which extend continuously through the carrier film from the first side of the carrier film through to the second side of the carrier film.
摘要:
The invention relates to a method for producing stampings from thermally activatable adhesive films, said method being characterised in that a) a thermally activatable adhesive material is first applied to a first carrier material, and b) the thermally activatable layer of adhesive material is laminated onto a temporary carrier material (“release liner”) under the action of heat, during a subsequent step. The release liner comprises at least one surface based on polyolefins, said surface being non-tacky at room temperature and activatable under the action of heat in such a way that it has adhesive properties. The method is also characterised in that c) the thermally activatable layer of adhesive material on the release liner is subjected to a stamping process.

The invention relates to an adhesive film comprising at least one carrier film and at least one layer of an adhesive material. The invention is characterised in that the carrier film has a tensile strength of at least 50 MPa, measured according to ASTM D882, a haze value of no more than 3%, measured according to ASTM D1003, and a transmission of at least 80%, measured according to ASTM D1003, in light with a wavelength of 550 nm; and in that the adhesive film has a transmission of at least 70%, measured according to ASTM D1003. The invention also relates to the use of a corresponding single-sided or double-sided adhesive film, as an anti-splinter cover for glass windows, especially for electronic consumer items.
