Abstract
The present invention provides a porcelain enamel coating composition for use in forming a coating composition upon a metal substrate having an infrared reflectivity of at least 50% at 2.5 .mu.-microns measured with a Perkin Elmer Lambda 19 UV/VIS/NIR spectrometer with a labsphere RSA-PE 19 reflectance spectroscopy accessory. The coating composition comprises a glass component and a separate and distinct addition of cerium oxide. Preferably, the coating composition comprises from about 0.20% to about 3.0% by weight of the cerium oxide.
