  • Patent number: 8362124
    Abstract: The present invention relates to coating and printing ink compositions containing silylated polyether compounds comprising a hydrolysis-resistant bis-silyl hydrocarbylene group. More particularly, the silylated polyether compound comprising a bis-silyl hydrocarbylene group provides to the coating and ink compositions formulation flexibility over the entire pH range, leveling-and-flow and surface wetting, and are non-reactive with the other components of the coating and ink compositions, thereby providing long-term shelf-stability of formulated coatings and inks. These coating and ink compositions containing silylated polyether compounds do not release silicone materials and thereby provide articles treated with these coatings and ink compositions with uniform appearance and gloss.
