Evaluation of Adhesive Strength on Photo-thermal Dual Cured Polymers for Screen Printing

Abstract

Photo-thermal dual curing system was devised and applied to screen printing technology. New formulation of acrylic anchor resins contains a base polymer, which consists of hydrophilic units and solvent-absorbing units. As crosslinkers, multifunctional acrylates and polyurethane acrylates were employed. Adhesive strength of PET/anchor resin/PET and PET/anchor resin/Cu was evaluated. Adhesive strength was effectively enhanced by photo-thermal dual curing of the base polymer containing crosslinker.
