ABSTRACT:
The polyurethanes resulting from curing isocyanate-terminated urethane prepolymers with a N,N'-dialkylmethylenedianiline are broadly useful as coatings on the surface of objects made of metal, wood, glass, or plastic. Such coatings may be made based on either a 1-pack systemor 2-pack system. The diamine N,N'-di(2-butyl)4,4'-methylenedianiline is a particularly useful diamine.
