Kaneka’s MS Polymer has proven its quality and versatile application area over more than 20years in the adhesive & sealant market. However, to use it as the backbone polymer in PSA formulations, its moisture-curing step requires specific adaptations compared to a ‘normal’ PSA coating process (solvent, hotmelt or UV curable). But using them as an additive is pretty straightforward and easy in traditional PSA formulations (cf. acrylics, rubber,..). Thanks to the wide range of MS Polymer™ types going from low to relatively highmolecular weight, various levels of functionality and branching one can move properties in different directions depending on the selected type (or combinations).
Studies have been done on various acrylic PSA adhesives modified with different MS Polymer grades in different concentrations to quantify the performance shift and highlight the possibilities of MS PolymerTM.
