Abstract
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.
Claims22
1-15. (canceled)
A multilayer PSA assembly comprising:
- i. a propylheptyl acrylate adhesive copolymer layer comprising:
- a) from 50 to 99.5 weight percent of 2-propylheptyl acrylate as a first monomer;
- b) from 1.0 to 50 weight percent of a second non-polar monomer;
- c) from 0.1 to 15 weight percent of a third polar acrylate monomer;
- and
- d) an optional tackifying resin,
- wherein the weight percentages are based on the total weight of the copolymer;
- and
- ii. a second acrylate pressure sensitive adhesive foam layer.
