Abstract
Abstract UV curable coating compositions are provided based on the use of photoinitiator with the hydrolysis product of silylacrylate and aqueous colloidal silica. The UV curable silicone coating compositions also can contain polyfunctional acrylate. The UV curable hardcoat composition can be applied onto various substrates, for example, a polycarbonate substrate, and thereafter cured under UV radiation to produce adherent and abrasion resistant coated articles.
