Aziridine Crosslinkers

SpecialChem / Oct 6, 2010

Increasing pressure sensitive adhesives strength calls for crosslinking, but often at the cost of adverse side effects like discolouring. Now, an unusual crosslinker type promises to avoid those side effects. Today's pressure sensitive adhesives are so strong, they make predecessor products look inadequate. From shear holding capabilities originally designed for modest loads at room temperature, high performance pressure sensitive tapes can now support loads at elevated temperatures for a week1. This improved performance is generally delivered by crosslinking the pressure sensitive adhesive (PSA), although careful formulation is needed to retain high levels of tack and adhesion. However, that strength comes at a price.
