Hydroxy functional alkyl polyurea crosslinkers

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.

Compositions comprising hydroxy functional alkyl polyureas are disclosed.

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.

Reflective article having a sacrificial cathodic layer

An electrically conductive protective coating or film is provided over the surface of a reflective coating of a solar mirror by flowing or directing a cation containing liquid and an anion containing liquid onto the conductive surface. The cation and the anion containing liquids are spaced from, and preferably out of contact with one another on the surface of the reflective coating as an electric current is moved through the anion containing liquid, the conductive surface between the liquids and the cation containing liquid to coat the conductive surface with the electrically conductive coating.

Electrocurtain coating process for coating solar mirrors

A protective coating is applied to the electrically conductive surface of a reflective coating of a solar mirror by biasing a conductive member having a layer of a malleable electrically conductive material, e.g. a paste, against a portion of the conductive surface while moving an electrodepositable coating composition over the conductive surface. The moving of the electrodepositable coating composition over the conductive surface includes moving the solar mirror through a flow curtain of the electrodepositable coating composition and submerging the solar mirror in a pool of the electrodepositable coating composition. The use of the layer of a malleable electrically conductive material between the conductive member and the conductive surface compensates for irregularities in the conductive surface being contacted during the coating process thereby reducing the current density at the electrical contact area.
