UV Curable Hard Coats Mediated With Thiols

Qiang Hu

Abstract: UV curable hard coating systems for plastics face progressive expectations such as higher scratch resistance, more toughness, better exposure sensitivity and lower curing dose. Novel formulations for plastic substrates of PC, PC/ABS, PET and PMMA will be reported towards the purpose of addressing the challenges aforementioned mainly through thiol-ene click chemistry concept, without suffering the disadvantages of strong odor and short shelf life that are not unusual for thiol-ene based products.
