Enamel paint is paint that air-dries to a hard, usually glossy, finish, used for coating surfaces that are outdoors or otherwise subject to hard wear or variations in temperature; it should not be confused with decorated objects in "painted enamel", where vitreous enamel is applied with brushes and fired in a kiln. The name is something of a ...
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin vitreus, meaning "glassy".
Being a fired ceramic, porcelain enamel is also highly heat-resistant; this allows it to be used in high-temperature applications where an organic anti-corrosion coating or galvanization may be impractical or even dangerous (see Metal fume fever). [3] Porcelain enamel also sees less frequent employment of some of its other properties; examples ...
The masses consist of automotive paint which has hardened sufficiently to be cut and polished. [3] [2] It was formed from the buildup of layers of enamel paint slag on tracks and skids on which cars were painted with acrylic lacquer, which have been baked numerous times. [4] In recent times [when?] the material has been upcycled into jewelry ...
The process usually includes the fusing of coloured powder glass onto a substrate (metal, glass or ceramics) through intense heat (usually between 750 and 850 degrees Celsius or 1382 and 1562 degrees Fahrenheit). The powder melts and cures to a smooth, durable, glassy coating on metal, glass or ceramics. [5] [6]
The coating chemistry is waterborne enamel based on epoxy, an aminoalcohol adduct, and blocked isocyanate, which all crosslink on baking to form an epoxy-urethane resin system. [1] E-coat resin technology, combined with the excellent coverage provided by electrodeposition, provides one of the more effective coatings for protecting steel from ...
Vitreous enamel, a smooth, durable coating for metal, made of melted and fused glass powder; Enamelled glass, glass which has been decorated with vitreous enamel; Overglaze enamelling, painting on top of glaze in pottery
The surface finish is usually satin, but it can be turned glossy by coating in a clear high-gloss enamel. [8] On a microscopic scale dendrites form on the surface finish, which trap light and increase absorptivity. Because of this property the coating is used in aerospace, microscopy and other optical applications to minimise light reflection. [8]
