摘要： The present invention provides a composition for use in forming an opaque porcelain enamel coating on a metal substrate. A porcelain enamel coating formed using a composition according to the invention readily adheres to metal substrates such as, for example, steel, that are degreased-only. Furthermore, such a porcelain enamel coating displays an acid resistance of A according to ISO 2722 and good easy-to-clean properties. The composition according to the invention includes a glass component including by weight from about 45% to about 55% SiO 2 , from about 8% to about 17% B 2 O 3 , from about 1.8% to about 17.7% SrO + BaO, from about 1.9% to about 10% Li 2 O, up to about 6% ZrO 2 , from about 2% to about 11% TiO 2 , from about 1.5% to about 6% K 2 O, from about 1% to about 4% MoO 3 , from about 0.3% to about 13% Na 2 O, up to about 2% NiO, up to about 3% Al 2 O 3 , up to about 2.9% MnO, up to about 0.8% CoO, up to about 3% MgO, up to about 5% CaO, and up to about 2% Sb 2 O 3 .
