  • Publication number: 20180148371
    Abstract: An architectural transparency includes a substrate, a first dielectric layer formed over at least a portion of the substrate, a subcritical metallic layer formed over at least a portion of the first dielectric layer, a primer layer formed over the subcritical metallic layer and, a second dielectric layer formed over at least a portion of the primer layer. The primer layer contains an oxygen-capturing material that can be sacrificed during a deposition process or heating process to prevent degradation of the subcritical metallic layer.

  • Patent number: 9758426
    Abstract: The present invention relates to reflective articles, such as solar mirrors, that include a sacrificial cathodic layer. The reflective article, more particularly includes a substrate, such as glass, having a multi-layered coating thereon that includes a lead-free sacrificial cathodic layer. The sacrificial cathodic layer includes at least one transition metal, such as a particulate transition metal, which can be in the form of flakes (e.g., zinc flakes). The sacrificial cathodic layer can include an inorganic matrix formed from one or more organo-titanates. Alternatively, the sacrificial cathodic layer can include an organic polymer matrix (e.g., a crosslinked organic polymer matrix formed from an organic polymer and an aminoplast crosslinking agent). The reflective article also includes an outer organic polymer coating, that can be electrodeposited over the sacrificial cathodic layer.

  • Publication number: 20170075045
    Abstract: A solar reflective mirror includes a parting film between solar reflecting sublayers to improve optics and stability of the solar mirror. The coating stack of the solar reflector mirror is encapsulated to increase the useable life of the solar mirror, and to eliminate the need for a permanent protection overcoat. Omission of the PPO film which is electrically non-conductive makes the coating stack electrically conductive eliminating the need for a two layer encapsulant when the encapsulant is e-coated. Another feature of the invention is applying the base coat of the encapsulant over the marginal edges of the PPO film leaving a center section without coverage and adding the top coating of the encapsulant over the base coat and the uncoated area.
