To provide transparent plastic coatings with a combination of abrasion resistance and fbrmability, a composition comprises an aqueous-organic solvent mixture containing hydrolysis products and partial condensates of an epoxy functional silane and/or a diol functional organopolysiloxane mixed with a multifunctional crosslinker selected from multifunctional carboxylic acids, anhydrides or silylated anhydrides, wherein the molar ratio of the epoxy functional silane and/or the diol functional organopolysiloxane to the multifunctional crosslinker is from about 10:1 to 1:10, and water in an amount sufficient to hydroyze the components.
L'invention concerne des compositions de revêtement, des articles, et des procédés de revêtement d'articles. Les compositions de revêtement et les procédés de l'invention permettent d'obtenir des revêtements pouvant être mis en forme et résistant à l'abrasion lorsqu'ils sont durcis sur un substrat. Lesdits articles peuvent être formés après application et durcissement des compositions de revêtement sur un substrat.
