  • Translucent coating compositions providing improved UV degradation resistance
    Publication number: 20070155886
    Abstract: The present invention relates to substrates and coating compositions disposed thereon containing improved ultraviolet degradation resistance. Specifically, these coating compositions can contain multiple UV protectants and can advantageously be used in transparent, semi-transparent, and/or translucent coatings on substrates, particularly opaque or semi-opaque substrates such as wood, e.g., in order to inhibit, to reduce, and/or to minimize UV degradation of said substrates.
