The field of electron beam and ultraviolet light curable coatings was launched when polymer chemists established that reactive monomers could be rapidly polymerized by substituting radiation techniques for conventional polyerization initiators. In the case of electron beam (EB) curable coatings, it was demonstrated that acrylate based formulations polymerize by exposure to accelerated electrons in the 150,000 to 500,000 electron volt (ev) range. These highly reactive electrons are capable of initiating polymerization by directly fragmenting molecules contained within the irradiated medium. Experimentation with other forms of energy paved the way to the development of (uv) curable coatings. In uv curable compositions, a uv light (photon) absorbing species is incorporated into the formulation which, upon absorption of a particular wavelength of light, photochemically produces a reactive species capable of initiating polymerization.
