Rubans adhésifsIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Pressure-sensitive adhesives (PSAs) have been an integral part of many industries that require the bonding of two or more materials. PSAs are commercially available in many forms: hot/warm melts, solvent borne, water based and syrups. They are used for applications as simple as paper labels to high-performance tapes used to bond two pieces of an automobile. Regardless of the application, PSAs have a set of viscoelastic properties that exhibit permanent adhesion characteristics once applied to a substrate. These adhesion characteristics are constant outside the typical responses from degradation from external environmental conditions, such as temperature and chemical exposure.
With advancements in technology over the past decade, applications now exist that require PSAs to show different adhesion performances at different stages of the application process. An example would be a PSA that exhibits properties like a removable label at application, but transposes to a high-strength PSA similar to an HVAC tape in a second stage, when activated by an external stimuli. This concept extends beyond just transposition from one PSA state to another; it can also include transpositions from a PSA state to a structural bond. Additional uses include the need for transposition from high adhesion to low adhesion (debond on demand) that has been heavily researched and well documented.2-6
PSAs can transpose from low adhesion properties to high adhesion properties via precise thermal- or UV-activated chemistries. For structural adhesive tape applications, improved tape stability enables the adhesive to be supplied in tape form for easy and efficient application through controlled bond lines, which is an advantage over the less-favorable approach of using applicator guns.Note de contenu : - Table 1.
