Smart UV/EB Curable Pressure Sensitive Adhesives

Harmonie Milet-Billis, Sartomer Americas

Abstract:Energy Curable Pressure Sensitive Adhesives (PSA) offer advantages such as high through-put, low VOCs and no pre-heating or drying requirements. Here-in, we present novel “Smart” UV/ EB curable PSAs that can further bond or de-bond upon an external stimulus. The unique chemistry and formulating approach allows for control over parameters such as tack, peel strength and shear. Specifically, a molecular engineering approach will be emphasized: tailor-made backbone (molecular structure) and functionality of oligomers to control rheological and PSA properties.
