Abstract

Provided herein are graft coating formulations for windows that can help reduce or prevent bird strikes via a combination of UV reflectivity and fluorescence. These graft coating formulations may include an acrylic monomer, a diacrylic monomer, a graft initiator, and a catalyst, and when applied to a glass or plastic substrate, may reflect more than about 70% incident light having a wavelength of less than 400 nm, and also may fluoresce when exposed to light having a wavelength of less than about 400 nm. This combination of reflectivity and fluorescence may render the window visible to birds, while still appearing transparent to humans.
