Recent Progress in UV/EB Curable Pressure Sensitive Adhesives

Abstract:Energy Curable Pressure Sensitive Adhesives (PSA) eliminates the need for drying, solvent extraction or pre-heating steps (compared to traditional water/solvent-borne or hotmelts methods). This can be particularly suitable for temperature sensitive substrates or when the PSA has to be applied in-line. Here, we demonstrate structure-property relationships between formulation and PSA properties such as tack, peel, shear and temperature performance. Highlights include screening the viscosity-elastic properties through rheology and routes to high performance/ high shear adhesion failure temperatures (SAFT) PSAs.
