Abstract: Disclosed herein are stable organosiloxane coating compositions comprising a blocked isocyanate silane and at least one polyol that provide abrasion resistant coatings for transparent polymer substrates. The cured coatings also have excellent adhesion to the polymer substrates. In accordance with certain embodiments, the disclosed coating compositions, which when cured on the substrate, provide formable, weatherable, anti-fog, or combinations of formable, weatherable, or anti-fog organosiloxane coatings. Also disclosed herein are articles comprising coatings cured from such coating compositions, and processes for making the coating compositions.

Abstract: Disclosed herein are ultraviolet (UV) curable coating compositions that provide transparent, flexible, and abrasion-resistant coatings when cured on a substrate. The coating compositions comprise an adduct of a multifunctional acrylate monomer component and an amino-organofunctional silane; an organic solvent component; an acid; a colloidal silica component; and a multifunctional urethane acrylate oligomer component. The amino-organofunctional silane is represented by the formula XaSi[Q1(NHQ2)bNZH]4-a, where X is an alkoxy group having from 1 to 6 carbon atoms; Q1 and Q2 are the same or different divalent hydrocarbon groups; Z is a hydrogen or a monovalent hydrocarbon group; a is an integer from 1 to 3; and b is an integer from 0 to 6. Also disclosed herein are processes for preparing such coating compositions and articles comprising coatings cured from such coating compositions.
