  • Aspartic ester functional compounds
    Patent number: 7759452
    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.

  • Polyaspartimides
    Patent number: 7307140
    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.
