Abstract
Coating compositions comprising a polyurea formed from a reaction mixture comprising isocyanate and a (meth)acrylated amine are disclosed. The (meth)acrylated amine is the reaction product of a polyamine and a mono(meth)acrylate; the ratio of equivalents of isocyanate groups to equivalents of amine groups is greater than 1 and the isocyanate and the (meth)acrylated amine reaction product can be applied to a substrate at a volume mixing ratio of 1:1. Methods for using the coatings, and substrates coated therewith are also disclosed.
