  • Polyaspartimides
    Publication number: 20060106194
    Abstract: The present invention relates to novel polyaspartimides, their method of production and the use of these polyaspartimides as reactive components for polyisocyanates in two-component polyurethane coating compositions. The polyaspartimides are prepared by reacting a polyether amine with a maleimide.

  • Aspartic ester functional compounds
    Publication number: 20060011295
    Abstract: A functional aspartate prepared by A) reacting an aziridine with a Michael-acceptor molecule to form an aziridinyl aspartate, and B) reacting the aziridinyl aspartate with an active hydrogen containing compound to form the functional aspartate. The functional aspartate can be used in adhesive, sealant or coating compositions that also include an isocyanate functional material. The composition can be used in a method of bonding a first substrate to a second substrate that includes applying a coating of the above-identified adhesive composition to at least one surface of the first substrate or the second substrate, and contacting a surface of the first substrate with a surface of the second substrate, where at least on of the contacting surfaces has the coating applied thereto. The composition can also be used to coat substrates.

  • PROCESS FOR PREPARING ASPARTATES
    Publication number: 20050159560
    Abstract: The present invention relates to novel aspartates, their method of production and the use of these aspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers. The aspartates are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a maleimide.

  • Silane modified two-component polyurethane coating
    Publication number: 20050137322
    Abstract: A two-component coating composition that includes (a) a first component including a compound that contains trialkoxysilyl and isocyanate functional groups; and (b) a second component that includes a polyol and a catalyst. The two component coating composition can be used in a method of coating a substrate that includes applying the coating composition to at least a portion of a surface of the substrate, thus providing a substrate coated with the above-described two-component coating composition.
