Bird deterrent glass coatings

摘要

This invention pertains to UV-absorbing coatings that may optionally be covered with an anti-reflective layer and that are applied to exterior-facing surfaces such as a window or other glass surface that are transparent or translucent. Such coatings are visible to various species of birds, but are generally transparent to humans. The UV absorbing coatings have a silane- or silane-derived chromophore or a combination of a silane- or siloxane-based material and a chromophore, which chromophores absorb UV light at about 300 to about 400 nm. More particularly, the silane- or siloxane-based chromophore is 2-hydroxy-4-(3-triethoxysilylpropoxy)diphenylketone or a derivative thereof.

主权项

1. A method of preventing birds from colliding with a substrate, comprising:
applying a coating to at least a portion of a transparent substrate, wherein the coating comprises at least one of:
(a) a silane- or siloxane-based chromophore capable of forming stable bonds with a substrate, absorbing light at about 300 nm to about 400 nm and remaining transparent to humans, wherein the silane- or siloxane-based chromophore is chosen from hydroxyl diphenylketone or a derivative thereof; and(b) a composition comprising a silane and/or a siloxane and a chromophore, wherein the silane and/or siloxane is capable of forming stable bonds with a substrate, and the chromophore is capable of absorbing light at about 300 nm to about 400 nm, and applying an anti-reflective layer on an exterior facing surface of the coating, wherein the coating having a chromophore is perceived as opaque by a bird but is perceived as transparent to humans.
