    Abstract: A system for forming an elastomeric composition for application to a substrate includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes a polymeric polyisocyanate and optionally an isocyanate-terminated prepolymer. The isocyanate-reactive component is reactive with the isocyanate component and includes a polyol component and a polyetheramine. The polyol component is a mixture of (a) a hydrophobic polyol; (b) a polyether polyol different than the hydrophobic polyol and having a weight average molecular weight greater than 500 g/mol; and (c) a polyaminopolyol. The elastomeric composition is formed as the reaction product of the isocyanate component and the isocyanate-reactive component and may be applied as an elastomeric coating layer on a substrate such as a steel pipe. The steel pipe having the applied elastomeric coating layer satisfies the standard for use in the water supply industry as set forth in AWWA C222.

  • Patent number: 10428171
    Abstract: The present invention relates to a one-component processing method and system for preparing polyurea materials. This method and system involves a polymerization process using cyclic oligomeric polyurea precursors. These cyclic oligomeric precursors have dynamic urea bonds such as hindered urea bonds (HUBs). These cyclic oligomeric precursors exhibit dynamic properties to reversibly dissociate in situ yielding isocyanate and amine components which polymerize to yield the polyureas, such as linear, branched or cross-linked polyureas. This method and system has advantages over conventional methods that utilize two-component systems. Such two-component systems require the segregation of the isocyanate and amine components to prevent premature or too rapid polymerization. The resulting polyureas are useful for a variety of applications including coatings.

  • Patent number: 8349987
    Abstract: The disclosure relates to biocompatible components useful for forming compositions for use as medical/surgical synthetic adhesives and sealants. Biocompatible components of the present disclosure may include a polymeric polyol core, which may be treated with a nitroaryl compound to form a nitro ester. The resulting nitro ester groups may be reduced to form amino groups which, in turn, may be treated to form isocyanate groups. The resulting isocyanate may then be reacted with a second component to form adhesive and/or sealant compositions.

  • Patent number: 8318889
    Abstract: An organic polyurethane shape memory material includes a C10 chain or C18 chain and consists of hard segment and soft segment. The material is produced by reacting the single-chain type dendrimer with diethylenetriamine to produce dendrimer. Then dendrimer reacts with N-(3-aminopropyl)diethanolamine to produce dendritic diols. Next, polymer HO(C6H10O2)xC2H4OC2H4(C6H10O2)yOH, where x+y=25˜26, reacts with methylenedi-p-phenyl diisocyanate, and at least one type of dendritic diols is added to produce the organic polyurethane shape memory material.
