Abstract
A sealing and coating compound hardening in the presence of moisture and comprising a mixture of A. an addition product formed between an excess of a di- or poly-isocyanate having aliphatic or cycloaliphatic isocyanate groups and a polyester polyol or a linear or branched polyalkylene oxide having terminal hydroxy groups, and B. a di- or poly-functional enamine which is prepared by reacting an aliphatic aldehyde or cyclic ketone and a polyaminoamide which is the condensation product formed between an excess of a secondary diamine and at least one acid selected from the group consisting of di- and poly-carboxylic acids having 6 to 72 carbon atoms.
