Aspartates containing ketimine-groups and their use in coating compositions
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 aspartaes are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a ketone.
