1. A method of making an article, the method comprising:
- providing a first low-iron glass substrate, the first substrate having a thickness of about 0.5-3 mm;
disposing a reflective coating on a major surface of the first substrate;
disposing a UV radiation curable laminating adhesive over the reflective coating, wherein the laminating adhesive comprises from about 80 to 99.5% total oligomer, from about 1 to 5% adhesion promoter, and from about 0.1 to 1% photoinitiator;
providing a second glass substrate substantially parallel to the first substrate, the second substrate being oriented over the UV radiation curable laminating adhesive;
irradiating the substrates such that UV radiation causes the adhesive to become a solid polymer interlayer to laminate together the first substrate with the reflective coating disposed thereon and the second substrate to form a reflective article, wherein the laminating adhesive is cured using said UV radiation at a wavelength of from about 340 to 430 nm,wherein the reflective article has a reflectivity of at least 90 percent.

Abstract
Certain example embodiments relate to techniques for creating flat laminated mirrors, e.g., for use in concentrating solar power (CSP) applications. In certain example embodiments, the first substrate is a low iron glass substrate. A reflective coating is provided between the first and second substrates. The first and second substrates are laminated together via a radiation curable laminating adhesive with the reflective coating between the substrates. In certain example embodiments the radiation curable laminating adhesive is cured via UV radiation in order to form a laminated reflective article.
