Effect of drying conditions on adhesion strength of a pressure-sensitive adhesive

Regular surface roughness could be created on the of a pressure-sensitive adhesive (PSA) film through Marangoni flow during drying process. Therefore, tailoring both and bulk characteristics PSA consequently its adhesion strength expected by controlling conditions. Herein, properties water-based dried at various temperatures humidities were scrutinized. Increase in temperature improved to poly(ethylene terephthalate) due enhanced nanoroughness film. At constant humidity, higher Péclet number, number rougher surface. Drying humidity rise, however, more uniform distribution copolymers constituting PSA, better interdiffusion chains interface polymer particles prolonged process, increased free energy The similar here-defined viscoelastic dissipation ability, demonstrated power dependence nanoroughness. This newly-defined parameter considers taking advantage real regarding potentiality thorough wetting substrate with PSA.
