Abstract
The polyureas resulting from curing polyfunctional isocyanates having at least three isocyanate groups with a N,N'-dialkylmethylenedianiline are broadly useful as coatings on the surface of objects made of metal, wood, glass, or plastic. The diamine N,N'-di(2-butyl)4,4'-methylenedianiline is a particularly useful diamine. Biurets are an especially desirable class of polyisocyanates for the polyureas of this invention, particularly those arising from polymethylene diisocyanates and aromatic diisocyanates.
