Abstract:
A process for chemically grafting a coating onto a substrate comprising the steps of:a. providing a composition comprising a waterborne urethane acrylate at 20-30 parts per weight; an acryl-alkyd hybrid emulsion at 4-5 parts per weight; a polyether at 5-7 parts per weight; a defoamer at 0.1-0.2 parts per weight; a flattening agent at 1.5-3.0 parts per weight; a polyethylene glycol (400) diacrylate at 0.12-0.20 parts per weight; a de-ionized water at 4-50 parts per weight; ferrous ammonium sulfate (0.1% in de-ionized water) at 0.10-0.15 parts per weight; and a 2-hydroxy-2-methyl-1-phenyl-propane-1-one at 1.2-1.8 parts per weight; b. coating the substrate with the composition; and c. curing the composition coated on the substrate.
