Abstract:
Dual-sided adhesive articles include a first crosslinked pressure sensitive adhesive layer with a first major surface and a second major surface, a second siloxane-based pressure sensitive adhesive layer with a first major surface and a second major surface, such that the first major surface of the second siloxane-based pressure sensitive adhesive layer is in contact with the second major surface of the first crosslinked pressure sensitive adhesive layer. The articles also include a release liner having a microstructured surface with an array of microstructures, where the microstructured surface is in contact with the second major surface of the second siloxane-based pressure sensitive adhesive layer. The microstructures of the microstructured surface of the second siloxane-based pressure sensitive adhesive layer are unstable when not in contact with the microstructured release liner, and disappear over time when in contact with a substrate.
Abstract:
An adhesive tape comprising a core layer comprising a foam and having a first surface and a second surface opposite the first surface. The adhesive tape also comprises a first adhesive layer disposed about the first surface. And, the adhesive tape also comprises a second adhesive layer disposed about the second surface. At least one of the first and second adhesive layers comprises a radiation curable rubber based adhesive. The tapes are suitable for bonding an article to a target substrate having a low surface energy and for bonding under a variety of atmospheric conditions including at elevated temperatures.

Abstract:
Disclosed is a hot melt adhesive package (10) consisting of a cover layer (1) that is used as a first functional layer, e.g. as packaging, and a fusible filling that is used as a second functional layer. Said hot melt adhesive package (10) comprises two double-ply layers (3A, 3B), each of which consists of a cover ply (1A; 1B) and a filler ply (2A; 2B), the filler plies (2A; 2B) of the two double-ply layers (3A; 3B) lying on top of each other.
Abstract:
The present invention relates to a multilayer pressure sensitive adhesive (PSA) film having adhesive properties at its first and second main surface, wherein the film comprises at least two superimposed layers of a polymeric pressure sensitive adhesive foam material and optionally one or more intermediate layers of a polymeric foam material, wherein the PSA film is obtainable by a continuous self-metered process comprising the steps of (a) providing a substrate, (b) providing two or more coating knives which are offset, independently from each other, from said substrate to form a gap normal to the surface of the substrate, (c) moving the substrate relative to the coating knives in a downstream direction, (d) providing curable liquid precursors of the polymeric pressure sensitive adhesive foam materials and optionally of the polymeric foam material to the upstream side of the coating knives thereby coating the two or more precursors through the respective gaps as superimposed layers onto the substrate, (e) optionally providing one or more protective liners and applying these along the upstream side of the coating knives, and (f) curing the precursor of the multilayer film thus obtained, wherein a lower layer of the curable liquid precursor is covered by an adjacent upper layer of the curable liquid precursor, essentially without exposing said lower layer of a curable liquid precursor.
