Abstract:
The present invention relates to primer for promoting adhesion of an electroconductive metal oxide coating over a plastic substrate, to a method of making such a primer, and to a method of adhering an electroconductive metal oxide coating to a plastic substrate. The primer is a carbonate diol-based crosslinked polyurethane, and is more particularly the reaction product of a carbonate diol, a low molecular weight polyol and methylene diisocyanate.
Abstract:
An electrochromic window includes a first transparent, e.g., plastic, substrate having a first primer over at least a portion thereof and a first electrically conductive coating over at least a portion of the first primer. A second transparent plastic substrate has a second primer over at least a portion thereof and a second electrically conductive coating over at least a portion of the second primer. The first primer has a coefficient of expansion less than the coefficient of expansion of the first plastic substrate, and the second primer has a coefficient of expansion less than the coefficient of expansion of the second plastic substrate. An electrochromic medium is located between the first and second electrically conductive coatings. At least one of the first and second electrically conductive coatings has a metal layer located between first and second metal oxide layers.
Abstract:
Siloxane organic hybrid polymers and a method of making them by condensation polymerization reaction of organoalkoxysilane in the presence of organic film-forming polymers are disclosed. Alkali metal carboxylic acid catalyst is also disclosed, as well as the incorporation of cerium oxide for attenuation of ultraviolet radiation.
Abstract:
Describes a process for improving the adhesion of polymeric coatings to organic polymeric substrates and photochromic polymeric substrates. The process comprises irradiating the surface of a polymeric substrate prepared from or coated with a monomer composition having acrylic functionality in an oxygen containing environment with ultraviolet light; etching the treated surface; and applying to the etched surface a polymer-forming coating composition. Further described are articles and photochromic articles comprising in combination a polymeric substrate having on at least one surface thereof an adherent coating or photochromic coating prepared by the aforedescribed process.
Abstract:
The present invention relates to an aircraft transparency including an electroconductive metal oxide coating over a rigid plastic substrate, and a polyurethane protective liner over the metal oxide coating, and more specifically to the use of a primer for adhering the metal oxide coating to the substrate and/or a primer for adhering the polyurethane protective liner to the metal oxide coating. The metal oxide primer includes a carbonate diol-based crosslinked polyurethane. The polyurethane primer is selected from the group consisting of a crosslinked copolymer of acrylic acid and substituted acrylates such as 2-ethylhexylacrylate; a crosslinked copolymer of cyanoethylacrylate and acrylic acid; and a crosslinked terpolymer of 2-ethylhexylacrylate, cyanoethylacrylate and acrylic acid.
