Abstract: A composition includes specific amounts of a copolycarbonate and a roughening agent. The copolycarbonate contains first carbonate units derived from a first bisphenol monomer such that a homopolycarbonate of the first bisphenol monomer has a glass transition temperature less than 155° C., and second carbonate units derived from a second bisphenol monomer such that a homopolycarbonate of the second bisphenol monomer has a glass transition temperature of 155° C. or higher. The roughening agent includes a particulate crosslinked polymethylsilsesquioxane having a median equivalent spherical diameter greater than 5 micrometers and less than or equal to 10 micrometers.

Abstract: Methods may seal or seal a continuous clearance in a substrate and comprise a) producing or providing a bonding element comprising: i) an adhesive layer comprising an adhesive, ii) a carrier layer disposed on the adhesive layer and comprising a first carrier ply, and b) adhering the bonding element by means of the adhesive layer to the substrate, so that the bonding element completely covers the continuous clearance and the continuous clearance is fluid-tightly sealed by the bonding element. The bonding element comprises a pressure opening region which is surrounded at least sectionally by a weakening region formed in the carrier layer, the mean thickness of the carrier layer in the weakening region being lower than the mean thickness of the carrier layer in the pressure opening region.

Abstract: A blank and/or diecut permanently closes of holes in metal sheets and/or in plastic parts. The blank and/or diecut comprises at least one carrier having a laminate of at least two polymeric films, wherein the lower film has a basis weight of at least 1.5 kg/m2 and the side of the lower film opposite the upper film has an applied adhesive thereon.

Abstract: Method for bonding a sheetlike cover material to a shaped article, using an adhesive film comprising at least one layer of a heat-activatedly bondable adhesive, where the adhesive film is disposed, over the full area or a partial area, between the cover material and the shaped article, the heat-activatedly bondable adhesive as yet not adhering to the shaped article, wherein the cover material is pulled onto the shaped article under tension, so that the layer of the heat-activatedly bondable adhesive contacts the shaped article, and the activation of the heat-activatedly bondable adhesive is brought about by means of the pressure resulting exclusively from the tension, and optionally of heat introduced by means of external energy supply, whereby the heat-activatedly bondable adhesive adheres to the shaped article and a durable connection of the cover material to the shaped article is produced.
