  • Patent number: 8143345
    Abstract: Fluorinated polyurethanes and methods of making the same are provided. The fluorinated polyurethanes are useful for making polyurethane coating compositions for use in aerospace and other applications. The method includes a “split process” by which a hydroxypolyalkylenoxy derivative of a perfluoropolyoxyalkane is separately reacted with isocyanate to produce an isocyanate-terminated compound. The isocyanate-terminated compound is then reacted with an emulsifier to produce an acid- and hydroxyl-functional compound. The acid- and hydroxyl-functional compound is then reacted with isocyanate to form an acid-functional, isocyanate-terminated compound. The acid-functional, isocyanate-terminated compound is then reacted with at least one polyol to produce a higher molecular weight, acid- and hydroxyl-functional compound. Finally, the acid functional groups of the high molecular weight, acid- and hydroxyl-functional compound are neutralized to form a fluoro-urethane salt which is dispersed in water.

  • Patent number: 8143370
    Abstract: One-part moisture curable sealant compositions and methods of making the same are provided. The composition includes a silane-terminated polythioether component and a catalyst. The silane-terminated polythioether component and catalyst are isolated from moisture to prevent curing. The composition is stable against curing at ambient temperature and under conditions substantially free of moisture. When the composition is applied to a substrate and exposed to moisture, the composition cures to form a sealant. A method of making a sealant composition includes reacting a mercapto-terminated polythioether with a compound having a silane group to form a silane-terminated polythioether. The silane-terminated polythioether is then combined with a catalyst and isolated from moisture to prevent curing. Lastly, the composition is applied to a substrate and exposed to moisture which allows the composition to cure to form a sealant.
