The present disclosure relates to a pressure sensitive adhesive assembly comprising at least a first pressure sensitive adhesive layer comprising a hollow non-porous particulate filler material, wherein the surface of the hollow non-porous particulate filler material is provided with a hydrophobic surface modification. The present disclosure also relates to a method of manufacturing such a pressure sensitive adhesive assembly.

Pressure sensitive adhesive assembly comprising filler material

The present disclosure is directed to a multilayer pressure sensitive adhesive (PSA) assembly, comprising at least one pressure sensitive adhesive layer and a polymeric foam layer, wherein the pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition comprising a reaction product of a polymerizable material comprising: a) 2-propylheptyl acrylate as a first monomer; and optionally b) a second monomer having an ethylenically unsaturated group. The present disclosure is also directed to a method of manufacturing such a multilayer PSA assembly.

Multilayer pressure-sensitive adhesive assembly

The present disclosure relates to a multilayer pressure sensitive adhesive assembly comprising at least a first pressure sensitive adhesive layer superimposed to a second polymer layer, wherein a curable liquid precursor of the first pressure sensitive adhesive polymer layer comprises a low Tg (meth)acrylate copolymer and a high Tg (meth)acrylate copolymer having a weight average molecular weight (Mw) of above 20,000 Daltons. The present disclosure also relates to a method of manufacturing such a pressure sensitive adhesive assembly and uses thereof.
