Abstract
A low odor, fast curing composition coating composition with improved safety and mechanical properties, which cures readily under ambient conditions comprises a) a reactive polymer, oligomer or prepolymer having pendant acrylate or methacrylate groups, b) low odor acrylate or methacrylate monomers, c) an acrylate or methacrylate crosslinker, d) an isocyanate crosslinker, e) a thermal or photo active initiator, and optionally a reactive diluent and/or bead polymer. The composition is cured through multiple pathways, e.g., peroxide initiated radical curing and urethane step chain polymerization. Flooring and other construction materials coated with the composition are also provided.
