U.S. 8,158,191 B2
SDC Coatings, Inc. has been awarded a patent for a process for tinting a transparent, tintable, abrasion-resistant coating that is coated on at least one surface of a substrate, comprised of applying a polyurethane dispersion-based primer to at least one surface of a polycarbonate or polyamide substrate; contacting the primer applied to the substrate with a coating composition that forms a transparent, tintable, abrasion-resistant coating upon curing, the coating composition is comprised of an aqueous-organic solvent mixture having hydrolysis products and partial condensates of at least one of an epoxy functional silane and a diol functional organopolysiloxane, and at least one multifunctional crosslinker, wherein the multifunctional crosslinker is comprised of a silylated multifunctional anhydride, and wherein the at least one of the epoxy functional silane and the diol functional organopolysiloxane is present in a molar ratio to the multifunctional crosslinker from approximately 10:1-1:10; an amount of water sufficient to hydrolyze the at least one of the epoxy functional silane and the diol functional organopolysiloxane and the multifunctional crosslinker; and a blocked isocyanate; curing the coating composition to form a transparent, tintable, abrasion-resistant cured coating; and tinting the cured coating by immersing the coated surface of the substrate in a dye bath for the cured coating to absorb or transmit an amount of dye sufficient to allow up to 50% light transmittance through the coated substrate.
