Abstract:
1. A method for providing a coated vehicle transparency, comprising the steps of: a) providing a vehicle transparency having a glass substrate with a peripheral area; and b) applying a coating composition to at least a portion of the peripheral area of the transparency to reduce noise permeating into a vehicle, wherein the coating composition comprises an aqueous dispersion of polymeric microparticles prepared from components comprising: (i) a functional material selected from (a) a nitrile functional material, (b) an amide functional material, and (c) a carbamate functional material; (ii) a polyoxyalkylene acrylate; and (iii) a filler material; and further comprising at least partially drying the coating composition to provide a coating upon the transparency for inhibiting sound transmission therethrough.
