Hard, scratch-resistant, acrylate-based components are used in coatings for plastic substrates in a broad range of applications, from electronics, communications, semiconductor and data storage to optics, automotive, aerospace and medical devices. Just as the applications are wide and diverse, the variety of plastics that may be used has increased over time, and now includes materials such as polyethylene teraphthalate (PET), poly(methyl methacrylate) (PMMA) and polycarbonate (PC).
