Abstract:

A radiation curable coating for a floor comprising: at least one radiation curable oligomer, at least one photoinitiator and at least one reactive diluent monomer, said radiation curable oligomer being selected from the group consisting of Urethane (meth)acrylates, epoxy (meth)acrylates, polyester (meth)acrylates, acrylic (meth)acrylates, and hydrocarbon (meth)acrylates is described and claimed. The composition is capable of undergoing photopolymerization when coated on a floor and when irradiated by a light emitting diode (LED) light, having a wavelength from about 100 nm to about 900 nm, to provide a cured coating on the floor, with the cured coating having an external surface, and the cured coating having a Percent Reacted Acrylate Unsaturation (% RAU) at the external surface of about 60% or greater. Also described and claimed are the process to coat a floor with the LED curable coating for floor and a coated floor where the coating has been cured by application of LED light.
