Abstract
Abstract A free-radical polish composition is described. The composition can be applied and cured as an ultra thin film on finished surfaces to provide enhanced chemical and mar resistance. The composition comprises an aqueous emulsion including an olefin-functional polymer having low glass transition temperature or an olefin-functional prepolymer, and a silicone or silicone copolymer preferably with photoinitiators for UV and EB cure. The polish/emulsion can be applied, for example, to wet the surface of nitrocellulose lacquer wood finishes. The polish wet surface is first wiped to remove excess polish and thereafter exposed to UV radiation to provide a thin, polymerized permanent protective film on the polished surface.
