Evaluation of Adhesion Using Different Formulations, Substrates, and Curing Protocols
Neil Cramer, CPS
Abstract: UV curable formulations must adhere to a wide range of substrates while also achieving a wide range of different material properties. In this study we evaluate adhesion of different formulations on a range of different substrates including polymer, metal, and glass. Urethane acrylates, epoxy acrylates, polyester acrylates, and thiol-ene based formulations are evaluated while systematically varying formulation viscosity and thickness. Formulations are cured using both broadband mercury as well as LED lights.
