A water-resistant porcelain enamel coating and method of making the same is provided. The porcelain enamel coating is prepared using a ground glass, preferably a borosilicate glass frit, and mill additions of silica or silicon carbide and a zirconia compound. The mixture is applied to a metal substrate and fired, resulting in a water-resistant coating that resists cracking and crazing. The coating is particularly useful in water heaters.
Revêtement d'émail de porcelaine résistant à l'eau et son procédé de fabrication. On prépare ce revêtement au moyen de verre concassé, de préférence, une fritte de verre de borosilicate, et d'apports broyés de silice ou de carbure de silicium et d'un composé de zircone. On applique ce mélange à un substrat métallique et on le cuit, ce qui permet d'obtenir un revêtement résistant à l'eau empêchant les craquelures et les fissures. Ce revêtement est particulièrement utile dans des chauffe-eau.
