Problems solved by technology
Additionally, the partial solutions described generally do not provide an industrially viable solution for producing pressure sensitive adhesives with acceptable properties, particularly for specialized applications such as on-vehicle tape sealing and weather stripping applications. Thus, successful tape bonding is required on challenging topologies such as spot welds

Abstract
The present disclosure relates to a pressure sensitive adhesive assembly suitable for bonding to a substrate provided with an uneven surface, wherein the pressure sensitive adhesive (PSA) assembly comprises a polymeric foam layer comprising a polymeric base material, and having a complex viscosity comprised between 2,000 Pa.s to 80,000 Pa.s, when measured at 120C according to the test method described in the experimental section. The present disclosure is also directed to a method of applying the pressure sensitive adhesive assembly to the substrate provided with the uneven surface, and uses thereof.
Description
technical field [0001] This disclosure relates generally to the field of adhesives, and more particularly to the field of pressure sensitive adhesives (PSAs). The present disclosure also relates to methods of applying such pressure sensitive adhesives and uses thereof. Background technique [0002] Adhesives have been used for a variety of marking, securing, protecting, sealing and masking purposes. Adhesive tapes generally include a backing or substrate and an adhesive. One type of adhesive that is particularly preferred for many applications is represented by pressure sensitive adhesives. [0003] In fact, pressure sensitive tape is ubiquitous in homes and workplaces. In the simplest construction of a pressure sensitive tape, it includes an adhesive and a backing, and the overall construction is tacky at use temperatures and adheres to a variety of substrates using only moderate pressure to form a bond. In this way, the pressure sensitive tape constitutes a complete, s...
