Abstract: An autohesive polymer material that includes: at least one polymer having at least two terminal silyl groups of the Formula (1) given by: Si(R1)a(R2)b  (1). Each of the radicals R1 comprises an alkyl, alkenyl or aryl group or a hydrogen atom. Each of the radicals R2 comprises a group that can be eliminated with water, b is 1, 2 or 3, and a is 3−b. The polymer material further includes at least one condensation catalyst. Further, the polymer material is chemically precrosslinked and further crosslinkable with moisture. In addition, the polymer material is configured for use as a layer body that can be applied to a substrate. The polymer material of this kind can also be used for producing permanent bonds.

Abstract: Method for uniform coating of a composition onto a carrier material in web form, through the use of a coating apparatus comprising at least one element A, that forms with a further element B a nip ahead of which the composition is held up, and that moves relative to the element B in such a way that a rotating body of composition is developed and the composition is conveyed into the nip; comprising introduction of the composition into the intake region of the nip, the application of the composition to a carrier material in web form in the nip or after the composition has travelled through the nip, and which limits the longitudinal extent E of the nip intake region fully fillable by the body of composition.

Abstract: A plate cylinder for multiple mounting of flexographic printing plates is provided. The plate cylinder has an outer circumferential surface and a longitudinal axis. It comprises an adhesion layer attached to the plate cylinder, the adhesion layer comprising a carrier sheet with a mounting surface side facing the plate cylinder and an adhesion surface side facing radially outwards in relation to the longitudinal axis; and a plurality of adhesion elements. Each of these adhesion elements includes an elongated body extending radially outwards in relation to the longitudinal axis and an end face for attaching the printing plate by an adhesive bond, wherein the end faces of the adhesion elements form the adhesion surface side.

Abstract: Crosslinker-accelerator system for the thermal crosslinking of polyacrylates with functional groups suitable for entering into linking reactions with cyclic ethers, more particularly epoxide groups or oxetane groups, comprising at least one substance containing epoxide or oxetane groups (crosslinker) and at least one substance with an accelerating action for the linking reaction at a temperature below the melting temperature of the polyacrylate (accelerator).
