Timescales and properties of PSA (pressure sensitive adhesives).

The adhesive performances of a PSA are usually defined by three properties: tack, shear resistance, and peel strength. All these properties can qualitatively be correlated to the linear viscoelastic spectrum of PSA. In many cases, selected frequency intervals can be isolated within the linear viscoelastic spectrum, representing 'windows' associated to the in-service performances of the adhesive Indeed, the 'fine tuning' of linear viscoelastic properties was considered by PSA manufacturers of being a tool to tailor the individual products in order to meet the user's requirements in different applications, a case that in not reflected in our work.
