Technical Dictionary of Industrial Enamel in Five Languages

Brief Technical Dictionary

It consists of the property of enamel to form a permanent chemical-physical bond at the point of interface between the vitreous material and the metal surface.
Property of electrostatic powder to adhere to the metal surface. The higher the adhesion, the more material attaches electrostatically to the metal.
Resistance of porcelain enamel to the action of weak acids. It is a fundamental requirement for enamelling on many types of enamel surfaces that are meant to be in contact with acid substances.
Enamel powder with oil additives that confer the enamel the property of adhering on the metal surface by electrostatic effects. Despite it requires particular technologies, the electrostatic application offers many advantages, in particular it doesn’t need a drying step.
Short for “Easy to clean”. It’s a fundamental characteristic of some enamelled surfaces such as ovens, hobs, pottery etc.
Vitreous component of porcelain enamel, obtained by fusion and rapid cooling (thermal shock). It can be in the form of flakes or granules according to the production method. The name “frit” comes from the frying sound it makes during thermal shock.
Treatment for the removal of impurities from the metal surface, such as rust, mill scale or other inorganic contaminants. The cleaning is obtained by the use of acids, detergents and heat and it is a fundamental preliminary procedure to enamelling.
Metal oxide power used for enamel colouring. The wide range of pigments at our disposal makes it possible for enamel to rely on a large colour palette.
An inorganic glass-based coating used to protect the metal or to improve its aesthetics, which is smelted at 480-900°C to form a permanent chemical-physical bond on the metal surface.
Ready to Use. A type of porcelain enamel that is ready for application and lacks only the water to be added by the customer before use.
Screen printing is a technique used to produce writings, images and logos etc. It consists of moving a blade across a silk screen to fill the open mesh apertures where the screening pastes wet the surface, while the parts that are not to be inked are blocked by an impermeable stencil. The screening pastes are specific products to get writings and logos on glass or on enamelled metal.
