Abstract
Coating compositions comprising a polyurea formed from a reaction mixture comprising isocyanate and an acrylated amine are disclosed. The (meth)acrylated amine is the reaction product of a polyamine and a (meth)acrylate; when the (meth)acrylate comprises a poly(meth)acrylate, the reaction product further comprises a mono(meth)acrylate and/or a monoamine. Methods for using the coatings, and substrates coated therewith, are also disclosed.
