Abstract
The present invention relates to a unique radiation curable coating formulation used in the manufacture of window films. The coating composition is a mixture of radiation polymerizable monomers. The mixture includes a triacrylate or a tetraacrylate and acrylic acid. The thickness of the coating after polymerization ranges between about 1 and 2.5 microns. The coating can be applied to metal substrates and is used to achieve a superior abrasion resistant coating having optimum infrared absorption, while using high infrared absorption components in the coating mixture. Typically, the coating is applied to metal, for example, to aluminum substrates used in the fabrication of insulating window film or window structures. A process for applying the coating to such substrates is also disclosed.
