Ferro Glass Systems has introduced black enamel 14303 for laminated glass windshields. This bismuth-containing black enamel is fired in standard sag-bend furnaces on the inside exposed surface (commonly called Surface 4). The enamel stops UV light penetration to protect the adhesive that bonds the glass to the car. Enamel 14303 has good gloss with high opacity and maximum blackness. It is distinguished by its wide firing range providing a broader processing window to accommodate the temperature gradient that can occur across the large glass pieces during firing. Ferro believes that this product's exceptional chemical durability makes it the only windshield enamel in the European market that passes the 72-hour Toyota test (H2SO4 exposure)
Ferro’s global R&D group continues to work on lower-cost and low-bismuth/bismuth-free glass enamels. Ferro Glass Systems plans to make more product launch announcements during 2011.
