<p>A method for providing a coated transparency, includes the steps of: (a) providing a transparency having a vision area and a non-vision area; and (b) applying a sound dampening coating composition to at least a portion of the non-vision area of the transparency. Where the coating composition is a polyurea coating composition, the coating composition can be formed from a reaction mixture including an isocyanate-functional component and an amine-functional component, wherein the ratio of equivalents of isocyanate groups to equivalents of amine groups is greater than 1, while the volume mixing ratio of the isocyanate-functional component to the amine-functional component is capable of being applied to a substrate at 1:1.</p> |
