    摘要： A metallic substrate coated at least in part with a multilayer coating composite, comprising at least one of an electrocoat layer, a base coat layer, and a clearcoat layer; and a polyurea formed from a reaction mixture comprising isocyanate and a (meth)acrylated amine reaction product of a monoamine and a poly(meth)acrylate is disclosed. The ratio of equivalents of isocyanate groups to equivalents of amine groups in the polyurea is greater than 1 and the isocyanate functional component and the (meth)acrylated amine functional component can be applied to the substrate at a volume mixing ratio of 1:1. A building comprising a building component coated at least in part with such a polyurea is also disclosed, as is a substrate coated at least in part with such a polyurea, wherein the ratio of equivalents or isocyanate to equivalents of amine groups is greater than 1.3:1.
