Abstract
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.
Claims18
A UV-absorbing coating capable of deterring birds from collision with a substrate having the coating thereon comprising,
- at least one of:
- (a) a silane- or siloxane-based chromophore capable of forming stable bonds with a substrate, and absorbing light at about 300 nm to about 400 nm;
- 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,
- wherein the UV absorbing coating is visible to birds appears generally transparent to humans.
A method of preventing birds from colliding with a substrate, comprising:
- applying to at least a portion of a substrate a UV-absorbing coating, the UV-absorbing coating comprising at least one of:
- (a) a silane- or siloxane-based chromophore capable of forming stable bonds with a substrate, and absorbing light at about 300 nm to about 400 nm;
- 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 wherein the substrate having the coating applied thereon is visible to birds, but generally transparent to humans.
A coated substrate capable of deterring birds from collision with a substrate having the coating thereon comprising at least one of:
- (a) a silane- or siloxane-based chromophore capable of forming stable bonds with a substrate, and absorbing light at about 300 nm to about 400 nm;
- 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, wherein the coated substrate is visible to birds, but generally transparent to humans.
